A variety of N-substituted acridone derivatives were synthesized to make a comparison of their properties according to the number of acridone unit and the nature of substituent. The spectroscopic and electrochemical investigations show that the properties of N-substituted acridone derivatives are substituent-dependent. With benzene, biphenyl, fluorene and carbazole as linkers, the acridone derivatives demonstrate the properties of acridone itself due to a very weak intramolecular charge transfer (ICT) between acridone and the linker. However, significant ICT process is observed when the electron withdrawing groups are involved to form the donor-acceptor systems with acridone as the electron donating groups, which is different from the previously reported results of which acridone is usually used as an electron acceptor. Moreover, thermally activated delayed fluorescence (TADF) is observed with anthraquinone as linker. The theoretical calculations reveal that the N-substitutions have more influences on the locations and energy levels of the LUMOs than those of the HOMOs.

A series of tetracationic quadrupolar chromophores containing three-coordinate boron p-acceptors linked by different p-bridges, namely 4,4′-biphenyl, 2,7-pyrene, 2,7-fluorene, 3,6-carbazole and 5,5′-di(thien-2yl)- 3,6-diketopyrrolopyrrole, were synthesized. While their neutral precursors 1-5 displayed highly solvatochromic fluorescence, the water-soluble tetracationic target molecules 1M-5M, did not, but their emission colour could be tuned from blue to pink by changing the p-bridge. Compound 5M, containing the diketopyrrolopyrrole bridge, exhibits the most red-shifted absorption and emission maxima and the largest two-photon absorption cross-section (4560 GM at 740 nm in MeCN). Confocal laser scanning fluorescence microscopy studies in live cells confirm localization of the dye at the lysosome. Moreover, the low cytotoxicity, and high photostability of 5M combined with two-photon excited fluorescence imaging studies demonstrate its excellent potential for lysosomal imaging in live cells.

The fish bioconcentration factor (BCF) is an important aspect within bioaccumulation assessments. Several factors have been suggested to influence BCF values – including species, developmental stage, mixture exposure, and calculation method. However, their exact contribution to variance in BCF values is unknown. Within this study we assessed the relative impact of these test characteristics on BCF values and analyzed the reproducibility of aquatic exposure bioconcentration tests. Linear mixed effects analyses were performed on a newly develop database to investigate the relationship between the response variable (i.e. lipid normalized log BCF values) and several test characteristics as fixed effects. Lower BCF values were observed for substances that were simultaneously applied with high molecular weight polycyclic aromatic hydrocarbons compared to single substance exposure (with an average difference of -0.81 log BCF). Also, lower BCFs upon kinetic determination were observed compared to steady-state BCFs (log BCF -0.27), and lower BCFs for species from the Ostariophysi subcohort level (log BCF -0.17 to -0.15). In addition, data analysis showed high variation within BCF values for single substances (average SD = log BCF 0.21), which questions the robustness of the current bioaccumulation assessments. For example, the 95% confidence range of a BCF value of 2500 ranges from 953 (‘not-bioaccumulative’) to 6561 (‘very bioaccumulative’). Our results show that the use of one single BCF leads to a high uncertainty in bioaccumulation assessments. We strongly recommend that within future bioconcentration studies, the used experimental design and test conditions are described in detail and justified to support solid interpretation.

Two new M8L4 tetrafacial nanotubes (T1 and T3) of different lengths have been synthesized in water using ligands L1 and L2, respectively, with acceptor cis-[(dch)Pt(NO3)(2)] (M) using coordination-driven self-assembly [where dch is 1,2-diaminocyclohexane, L1 is 1,4-di(pyrimidin-5-yl)benzene, and L2 is 4,4′- di(pyrimidin-5-yl)-1,1′-biphenyl]. In addition to complex T1, a tetrahedral cage of composition [M-12(L1)(6)] (T2) was also formed in the self-assembly reaction of ligand L1 with cis-[(dch)Pt(NO3)(2)]. The precise composition of the products (T1 and T2) in solution was confirmed by H-1 NMR and ESI-MS. Pure tube T1 was separated out by a crystallization technique and fully characterized by 1H NMR and X-ray diffraction. Temperature- and concentration-dependent NMR studies indicated no equilibrium between T1 and T2 in the solution phase, and the proportion of T1 and T2 in the mixture depends on the temperature of the reaction. In contrast to ligand L1, the self-assembly of the longer ligand, L2, with cis-[(dch)Pt(NO3)(2)] gave only tetrafacial tube [M-8(L-2)(4)] (T3) without any tetrahedral cage.

A series of phosphonate ester supported lanthanide complexes bearing functionalities for subsequent immobilisation on semiconductor surfaces are prepared. Six phosphonate ester ligands (L1-L6) with varying aromatic residues are synthesised. Subsequent complexation with lanthanide chloride or -nitrate precursors (Ln = La, Nd, Dy, Er) affords the corresponding mono- or dimeric lanthanide model complexes [LnX(3)(L1-L3 or L5-L6)(3)](n) (X = NO3, Cl; n = 1 (Nd, Dy, Er), 2 (La, Nd)) or [LnCl(2)Br(L4-Br)(2)(L4-Cl)](n) (n = 1 (Nd, Dy, Er), 2 (La, Nd)) (1-32). All compounds are thoroughly characterised, and their luminescence properties are investigated in the visible and NIR spectral regions, where applicable.

A novel family of N-heterocyclic carbene (NHC)-incorporated Se-Fe-Cu compounds, bis-1,3-dimethylimidazol-2-ylidene (bis-Me-2-imy)-containing compound [(mu(4)-Se)Fe-3(CO)(9){Cu(Me-2-imy)}(2)] (2), bis-N-methyl- or bis-N-isopropyl-substituted benzimidazol-2-ylidene (bis-Me-2-bimy or bis-Pr-i(2)-bimy)-incorporated compounds [(mu(4)-Se)Fe-3(CO)(9){Cu(Me-2-bimy)}(2)] (3) or [(mu(4)-Se)Fe-3(CO)(9){Cu(Pr-i(2)-bimy)}(2)] (4), and a bis-1,3-dimethyl-4,5-dichloroimidazol-2-ylidene (bis-Me-2-Cl-2-imy)-containing compound [(mu(3)-Se)Fe-3(CO)(9){Cu(Me-2-Cl-2-imy)}(2)] (5), were synthesized in moderate yields in facile one-pot reactions of the ternary pre-designed compound [(mu(3)-Se)Fe-3(CO)(9){Cu(MeCN)}(2)] (1) with the corresponding imidazolium salts and (KOBu)-Bu-t in THF in an ice-water bath. Single-crystal X-ray analyses revealed that the Me-2-imy compound 2 or the Me-2-bimy compound 3 each exhibited a trigonal bipyramidal SeFe3(CO)(9)Cu geometry with an Fe2Cu plane further capped by a Cu(Me-2-imy) or Cu(Me-2-bimy) fragment, respectively, with one long Cu-Cu covalent bond. In addition, compound 4 also comprised a trigonal bipyramidal SeFe3(CO)(9)Cu core structure, but the second Cu(Pr-i(2)-bimy) group bridged the equatorial Fe-Fe edge with two unbonded Cu atoms, due to the presence of a sterically bulky Pr-i(2)-bimy fragment. On the other hand, the strong electron-withdrawing chloro-containing NHC compound 5 showed a comparatively open tetrahedral SeFe3(CO)(9) metal core, where two Fe-Fe edges each were further bridged by a Cu(Me-2-Cl-2-imy) fragment. Due to the nonclassical C-H center dot center dot center dot O(carbonyl) hydrogen bonds between the CO groups of the SeFe3(CO)(9)Cu-2 core and CH moieties of the neighboring NHC ligands, both compounds 2 and 3 comprised a one-dimensional network, while compounds 4 and 5 each were made up of a two-dimensional framework in the solid state, which efficiently enhanced the stability of these Se-Fe-Cu NHC compounds. Importantly, all of these synthesized Se-Fe-Cu NHC compounds 2-5 had pronounced catalytic activities for the homocoupling of arylboronic acids with high catalytic yields. Finally, these Se-containing Fe-Cu NHC compounds further represented excellent models for studying chalcogen effects in comparison to their Te analogs, as demonstrated by their catalytic performances and electrochemical behaviors, and by DFT calculations.

Many interesting target guest molecules have low symmetry, yet most methods for synthesising hosts result in highly symmetrical capsules. Methods of generating lower symmetry pores are thus required to maximise the binding affinity in host-guest complexes. Herein, we use mixtures of tetraaldehyde building blocks with cyclohexanediamine to access low-symmetry imine cages. Whether a low-energy cage is isolated can be correctly predicted from the thermodynamic preference observed in computational models. The stability of the observed structures depends on the geometrical match of the aldehyde building blocks. One bent aldehyde stands out as unable to assemble into high-symmetry cages-and the same aldehyde generates low-symmetry socially self-sorted cages when combined with a linear aldehyde. We exploit this finding to synthesise a family of low-symmetry cages containing heteroatoms, illustrating that pores of varying geometries and surface chemistries may be reliably accessed through computational prediction and self-sorting.

The synthesis of 7-conjugated organic materials through C-H activation and functionalization has recently received increasing attention. In this work, four pyrid-2-yl-appended para-phenylene oligomers (1-4) with two to five phenyl repeating units were synthesized via the Ru-catalyzed C-H activation of 2-phenylpyridine, followed by oxidative homocoupling or the arylation with a para-phenylene dibromide substrate. The single-crystal X-ray data and crystal packing of 1 and 3 are presented. In response to acid stimuli, the blue emissions of 1-3 are replaced by red-shifted cyan emissions, which are associated with the charge transfer transition from the phenylene backbone to the protonated pyridinium units. However, the emission of the longest congener 4 is largely quenched upon protonation. This lengthdependent emission property is rationalized by DFT and TDDFT calculations. (C) 2020 Elsevier Ltd.

This study intends to design and prepare a new magnetic copper catalyst and its activity was assessed by carbon-carbon coupling reactions. For this purpose, 1-[3-(trimethoxysilyl) propyl] urea (TMSPU), hydrazine and CuI were used sequentially to modify Fe3O4@SiO2 core-shell magnetic nanoparticles to obtain an efficient magnetic transition metal catalyst. Various analytical techniques were used to characterize the catalyst to show that the achieved structure and its properties are well-suited for coupling reactions. Finally, Mizoroki-Heck and Ullmann coupling reactions were performed using Fe3O4@SiO2@PrNCu catalyst. The new catalyst offer simple synthetic procedure, convenient use for routine casework and low price. The Fe3O4@SiO2@PrNCu catalyst was easily separated by means of a permanent and ordinary magnet and the recovered catalyst was reused in six cycles without any significant loss of activity.

The first unsubstituted olefin-linked covalent organic framework, termed COF-701, was made by linking 2,4,6-trimethyl-1,3,5-triazine (TMT) and 4,4′-biphenyldicarbaldehyde (BPDA) through Aldol condensation. Formation of the unsubstituted olefin (-CH=CH) linkage upon reticulation is confirmed by Fourier transform infrared (FT-IR) spectroscopy and solid-state C-13 cross-polarization magic angle spinning (CP-MAS) NMR spectroscopy of the framework and of its C-13-isotope-labeled analogue. COF-701 is found to be porous (1715 m(2) g(-1)) and to retain its composition and crystallinity under both strongly acidic and basic conditions. The high chemical robustness is attributed to the unsubstituted olefin linkages. Immobilization of the strong Lewis acid BF3 center dot OEt2 in the pores of the structure yields BF3 subset of COF-701. In the material, the catalytic activity of the guest is retained, as evidenced in a benchmark Diels-Alder reaction.
