Computational analyses of toxicological processes enables high-throughput screening of chemical substances and prediction of their endpoints in biological systems. In particular, quantitative structure-activity relationship (QSAR) models have been increasingly applied to assess the environmental effects of a plethora of toxic materials. In recent years, some more highlighted types of toxicants are endocrine disruptors (EDs, which are chemicals that can interfere with any hormone-related metabolism). Because EDs may significantly affect animal development and reproduction, rapidly predicting the adverse effects of EDs using in silico techniques is required. This study presents an in silico method to generate prediction data on the effects of representative EDs in aquatic vertebrates, particularly fish species. The protocol describes an example utilizing the automated workflow of the QSAR Toolbox software developed by the Organization for Economic Co-operation and Development (OECD) to enable acute ecotoxicity predictions of EDs. As a result, the following are determined: (1) calculation of the numerical correlations between the concentration for 50% of lethality (LC50) and octanol-water partition coefficient (K-ow), (2) output performances in which the LC50 values determined in experiments are compared to those generated by computations, and (3) the dependence of estrogen receptor binding affinity on the relationship between K-ow and LC50.

A mild and benign methodology to syntheses biaryls and 1,3-diynes has been demonstrated using the nickel nanoparticles supported on reduced graphene oxide (RGO-Ni) as a heterogeneous catalyst which is prepared using green reagents. A series of substituted biaryls and 1,3-diynes has been synthesised in good to excellent yields through C-C homocoupling reaction of arylboronic acids and terminal alkynes respectively using 1,4-dioxane as a benign solvent. The present ligand-free catalytic system proceeds smoothly under mild conditions, avoids noble and stoichiometric metal reagents and tolerates sensitive functional groups. Also has a wide substrate scope and feasible with other nitrogen and sulphur containing heteroaryl boronic acids. Hot filtration test unambiguously proves the true heterogeneity of the catalyst and which support for the further reusability of the catalyst for several times without any change in the activity. The easy preparation and simple magnetic separation, stability and reusability reveal that as-prepared RGO-Ni as a versatile catalyst for the synthesis of polyaromatic compounds both in academia and industries.

Developing efficient and wide spectrally acting photocatalysts for light-driven hydrogen production from water is highly desirable for solar energy conversion. Herein, diketopyrrolopyrrole (DPP) is used to combine with triphenylamine (TPA), bipyridyl (bdy), and biphenyl (bph) units for construction of conjugated microporous polymer photocatalysts. Although the synthesized two polymers, DPP-bdy-TPA and DPP-bph-TPA, have a similar framework structure, the former bearing a hydrophilic , bipyridyl unit displays much better photocatalytic performance with hydrogen production rates of 6918 and 2780 mu mol g(-1) h(-1) under a full-arc xenon lamp and visible light (>440 nm) illumination, respectively. Moreover, DPP-bdy-TPA has a wide photoaction spectrum with apparent quantum yields of 9.60% at 420 nm, 7.32% at 500 nm, and 0.31% at 600 nm, the so high values rarely achieved by present-known organic semiconductor photocatalysts. These results undoubtedly prove DPP is an excellent building block, and this work well exemplifies its utilization for construction of high-performance photocatalysts.

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 photochemical C-N coupling of aryl halides with nitroarenes is demonstrated for the first time. Catalyzed by a Ni-II complex in the absence of any external photosensitizer, readily available nitroarenes undergo coupling with a variety of aryl halides, providing a step-economic extension to the widely used Buchwald-Hartwig C-N coupling reaction. The method tolerates coupling partners with steric-congestion and functional groups sensitive to bases and nucleophiles. Mechanistic studies suggest that the reaction proceeds via the addition of an aryl radical, generated from a Ni-I/Ni-III cycle, to a nitrosoarene intermediate.

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.

A copper-catalyzed iodination of carbazoles has been developed. Barluenga’s reagent IPy2BF4 is used to generate a soft electrophilic halonium species for the iodination of the carbazoles. This report represents the first concept of copper-catalyst-promoted electrophilic halogenation of carbazoles. We demonstrated numerous applications of this methodology synthesizing diverse carbazole derivatives, i.e., both electron-rich and electron-deficient systems.

We report on the first experimental and theoretical investigations of ultrafast intramolecular energy transfer for a novel class of highly luminescent materials – nanostructured organosilicon luminophores (NOLs). For this purpose we designed, synthesized and investigated a NOL, (POPOP)Si-2(3Ph-EH)(6), consisting of six p-terphenyl (3Ph) donor and 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP) acceptor luminophores – well-known laser dyes widely used in plastic scintillators as an activator and a spectral shifter, respectively. The NOL shows excellent optical properties – molar absorption coefficient up to 2.6 x 10(5) L mol(-1) cm(-1), photoluminescence quantum yield up to 96% and pseudo Stokes shift of 100 nm. Its intramolecular energy transfer efficiency determined from steady-state optical measurements was found to be 93%, while the excitation lifetime was less than 1 ns. For deeper understanding of the processes of intramolecular energy transfer within NOLs, ultrafast spectroscopy investigations of the NOL, model donor and acceptor luminophores were performed for the first time for this class of compounds. It was found that the time constant of the energy transfer from donor to acceptor luminophores within the NOL is tau(1) = 105 fs, which is significantly faster than the vibrational relaxation within the donor (ca. 400 fs). Based on these findings, a kinetic scheme of the electronic excitation energy deactivation processes in the NOL was developed. The results obtained not only directly prove that the mechanism of energy transfer within the NOLs is based on Forster resonance energy transfer of the excitation energy from donor to acceptor luminophores, but also highlight the advantages of NOLs and NOL-based materials for future photonics applications – fast and efficient plastic scintillators, scintillating fibers and other spectral shifting optical materials.
