Aryl sulfones and phosphine oxides are widely used as molecular building blocks for host materials in the emissive layers of organic light-emitting diodes. In this context, the chemical stability of such molecules in the triplet state is of paramount concern to long-term device performance. Here, we explore the triplet excited-state (T-1) chemical stabilities of aryl sulfonyl and aryl phosphoryl molecules by means of UV absorption spectroscopy and density functional theory calculations. Both the sulfur-carbon bonds of the aryl sulfonyl molecules and the phosphorus-carbon bonds of aryl phosphoryl derivatives are significantly more vulnerable to dissociation in the T-1 state when compared to the ground (S-0) state. Although the vertical S-0 -> T-1 transitions correspond to nonbonding -> pi-orbital transitions, geometry relaxations in the T-1 state lead to sigma-sigma* character over the respective sulfur-carbon or phosphorus carbon bond, a result of significant electronic state mixing, which facilitates bond dissociation. Both the activation energy for bond dissociation and the bond dissociation energy in the T-1 state are found to vary linearly with the adiabatic T-1-state energy. Specifically, as T-1 becomes more energetically stable, the activation energy becomes larger, and dissociation becomes less likely, that is, more endothermic or less exothermic. While substitutions of electron-donating or -accepting units onto the aryl sulfones and aryl phosphine oxides have only marginal influence on the dissociation reactions, extension of the pi-conjugation of the aryl groups leads to a significant reduction in the triplet energy and a considerable enhancement in the Ty-state chemical stabilities.

Polyelectrolytes play an important role in both natural biological systems and human society, and their synthesis, functional exploration, and profound application are thus essential for biomimicry and creating new materials. In this study, we developed an efficient synthetic methodology for in situ generation of azonia-containing polyelectrolytes in a one-pot manner by using readily accessible nonionic reactant in the presence of commercially available cheap ionic species. The resulting polyelectrolytes are emissive in the solid state and can readily form luminescent photopatterns with different colors. The azonia-containing polyelectrolytes possess extraordinary potency of reactive oxygen species (ROS) generation, enabling them to impressively kill methicillin-resistant Staphylococcus aureus (MRSA), a drug resistant superbug, both in vitro and in vivo.

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.

A Lewis base catalyst Trip-SMe (Trip = triptycenyl) for electrophilic aromatic halogenation using N-halosuccinimides (NXS) is introduced. In the presence of an appropriate activator (as a noncoordinating-anion source), a series of unactivated aromatic compounds were halogenated at ambient temperature using NXS. This catalytic system was applicable to transformations that are currently unachievable except for the use of Br-2 or Cl-2: e.g., multihalogenation of naphthalene, regioselective bromination of BINOL, etc. Controlled experiments revealed that the triptycenyl substituent exerts a crucial role for the catalytic activity, and kinetic experiments implied the occurrence of a sulfonium salt [Trip-S(Me)Br][SbF6] as an active species. Compared to simple dialkyl sulfides, Trip-SMe exhibited a significant charge-separated ion pair character within the halonium complex whose structural information was obtained by the single-crystal X-ray analysis. A preliminary computational study disclosed that the pi system of the triptycenyl functionality is a key motif to consolidate the enhancement of electrophilicity.

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.

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.

Porous metal-organic frameworks (MOFs) have excellent characteristics for the adsorptive removal of environmental pollutants. Herein, we introduce a new series of highly stable MOFs constructed using Fe3+ and Al3+ metal ions and bisphosphinate linkers. The isoreticular design leads to ICR-2, ICR-6, and ICR-7 MOFs with a honeycomb arrangement of linear pores, surface areas up to 1360 m(2) g(-1), and high solvothermal stabilities. In most cases, their sorption capacity is retained even after 24 h of reflux in water. The choice of the linkers allows for fine-tuning of the pore sizes and the chemical nature of the pores. This feature can be utilized for the optimization of host-guest interactions between molecules and the pore walls. Water pollution by various endocrine disrupting chemicals has been considered a global threat to public health. In this work, we prove that the chemical stability and hydrophobic nature of the synthesized series of MOFs result in the remarkable sorption properties of these materials for endocrine disruptor bisphenol A.

Facile polymerization reaction conditions were developed for synthesizing conjugated polymers via direct arylation and the Buchwald-Hartwig aryl amination reactions under aerobic conditions. Refluxing the reaction solvent and using XPhos Pd G2 as a precatalyst proved to be a tolerant polymerization protocol for direct arylation polycondensation, which eliminates the need for an inert gas atmosphere and can successfully proceed using commercially available, reagent-grade N,N-dimethylformamide (DMF) as the solvent. This strategy was also successfully applied to the Buchwald-Hartwig aryl amination polycondensation in toluene, which provided poly(triarylamine)s in air.

A deep-blue thermally activated delayed fluorescence (TADF) emitter TXADO-spiro-DMACF has been reported for nondoped organic light-emitting diodes (OLEDs) by integrating an appropriate blocking unit with the donor (D)-acceptor (A)-donor (D)-type TADF emitter via a spiro linkage. Benefiting from the characteristic perpendicular arrangement, the intermolecular interactions are expected to be weakened to some degree. As a result, TXADO-spiro-DMACF shows a very small bathochromic shift of 8 nm associated with a narrowed full width at half maximum of 54 nm on going from solution to the film. The corresponding nondoped device successfully achieves a bright deep-blue emission, revealing Commission Internationale de l’Eclairage coordinates of (0.16, 0.09) and a peak external quantum efficiency of 5.3% (5.3 cd/A, 5.9 lm/W). The results clearly indicate that spiro-blocking is a promising strategy to develop deep-blue TADF emitters capable of nondoped OLEDs.
