Poly(arylamine)s were synthesized by poly-condensation of 4-n-octylaniline with 4,4′-dibromobiphenyl using the Buchwald-Hartwig aryl amination. Both the NH and the Br end groups were properly modified upon addition of an end-capping reagent in an appropriate ratio. The synthesized polymers contained many impurities, such as Pd, Br, and Cl, which decrease organic light-emitting diode performance. An investigation to reduce the impurities in the polymer showed that the purification solvent plays the key role in reducing the concentration of impurities in the polymer; purification with a nonchlorinated solvent, anisole, provided a highly pure poly(arylamine) even with a simple purification procedure. Moreover, the highly purified polymer material improved carrier mobility in hole-only devices.

The Name is 4,4′-Dibromobiphenyl. Through research, I have a further understanding and discovery of 92-86-4.

Constructing effective photocatalysts with visible light response to achieve rapid dehalogenation of polyhalogenated compounds remains a challenge nowadays. Herein, Pd nanoclusters-decorated TiO2 nanosheets with surface defects (Pd/TNS) are designed for polyhalogenated biphenyls dehalogenation under visible light. Pd/TNS is able to rapidly remove bromine atoms of 4-bromobiphenyl in 30 min. Experimental results reveal that oxygen vacancies and Ti3+ are in-situ generated in TNS during Pd photodeposition, which extend the absorption band edge of Pd/TNS to visible light region. Besides, the unique two-dimensional nanosheets structure of TNS contributes to a high surface area for high dispersion of Pd nanoclusters. Importantly, the Pd nanoclusters serve to activate carbon-halogen bond in polyhalogenated biphenyls and hydrogen-oxygen in H2O. The high dehalogenation efficiency could be assigned to a strong chemical interaction and synergistic effect between the Pd nanoclusters and TiO2(B) nanosheets. Finally, a collaborative mechanism is proposed for photocatalytic dehalogenation of polyhalogenated biphenyls on Pd/TNS.

The space integration of the lithiation of aryl halides, the borylation of aryllithiums, and Suzuki-Miyaura coupling using a Pd catalyst supported by a polymer monolith flow reactor without using an intentionally added base was achieved. To scale up the process, a series connection of the monolith Pd reactor was examined. To suppress the increase in the pressure drop caused by the series connection, a monolith reactor having larger pore sizes was developed by varying the temperature of the monolith preparation. The monolithic Pd reactor having larger pore sizes enabled Suzuki-Miyaura coupling at a higher flow rate because of a lower pressure drop and, therefore, an increase in productivity. The present study indicates that series connection of the reactors with a higher flow rate serves as a good method for increasing the productivity without decreasing the yields.

In this study, the electrochromic behavior of benzonitrile compounds were investigated. For this, a series of benzonitrile compounds with different chemical structures were synthesized and their electrochemical properties were investigated by cyclic voltammetry. Electrochromic behavior of the benzonitrile derivatives were also investigated by constructing sandwich type electrochromic devices and recording the changes in the UV-vis spectra as a function of applied potential. The compounds exhibited excellent electrochromic properties such as a high optical contrast, low driving voltage, good switching stability, high coloration efficiency, and a fast response time. All five compounds had different colors (orange, yellow-green, reddish-brown, green, blue) and driving voltages that were highly dependent on their chemical structures. The results indicate that benzonitriles are good electrochromic materials and should be of interest for applications such as electrochromic smart windows, information displays, and optical storage devices.

Chemoselective C-H arylations were accomplished through micellar catalysis by a versatile single-component ruthenium catalyst. The strategy provided expedient access to C-H-arylated ferrocenes with wide functional-group tolerance and ample scope through weak chelation assistance. The sustainability of the C-H arylation was demonstrated by outstanding atom-economy and recycling studies. Detailed computational studies provided support for a facile C-H activation through thioketone assistance.

Multiple studies have explored using cage silsesquioxanes (SQs) as backbone elements in hybrid polymers motivated by their well-defined structures and physical and mechanical properties. As part of this general exploration, we report unexpected photophysical properties of copolymers derived from divinyl double decker (DD) SQs, [vinyl(Me)Si(O-0.5)(2)][PhSiO1.5](8)[(O-0.5)(2)Si(Me)vinyl] (vinylDDvinyl). These copolymers exhibit strong emission red-shifts relative to model compounds, implying unconventional conjugation, despite vinyl(Me)Si(O-)(2) siloxane bridges. In an effort to identify minimum SQ structures that do/do not offer extended conjugation, we explored Heck catalyzed co-polymerization of vinyl-ladder(LL)-vinyl compounds, vinyl(Me/Ph)Si(O-0.5)(2)[PhSiO1.5](4)(O-0.5)(2)Si(Me/Ph)vinyl, with Br-Ar-Br. Most surprising, the resulting oligomers show 30-60 nm emission red-shifts beyond those seen with vinylDDvinyl analogs despite lacking a true cage. Further evidence for unconventional conjugation includes apparent integer charge transfer (ICT) between LL-co-thiophene, bithiophene, and thienothiophene with 10 mol % F(4)TCNQ, suggesting potential as p-type doped organic/inorganic semiconductors.

Carbon-nitrogen (C-N) bond-forming cross-coupling reactions catalyzed by palladium-based catalysts, the so-called Buchwald-Hartwig aminations, have been widely employed for the synthesis of pharmaceuticals and aryl-amine-based organic materials in academic and industrial settings. However, in solution, these reactions usually require glovebox and Schlenk line techniques, which greatly reduces their practical utility. Here, we report the development of operationally simple mechanochemical C-N cross-coupling reactions in the solid-state. Intensive investigations of various ball milling parameters revealed that the air-stable ligand tri(1-adamantyl)phosphine can be used to achieve solid-state coupling reactions between aryl halides and diarylamines with high efficiency. Notably, all experimental operations of the developed protocol can be carried out in air, thus providing a more convenient, industrially attractive, and sustainable alternative to conventional solution-based palladium-catalyzed C-N coupling reactions.

Newly designed dimethylamine-substituted triphenylamine (TPA) derivatives, N,N’-(1,4-phenylene)bis(N-(4-((tert-butyldimethylsilyl)oxy)phenyl)-N ”,N ”-dimethylbenzene-1,4-diamine) (NTPPA-2Si) and N,N’4(1,1′-biphenyl)-4,4′-diyl)bis(N-(4-((tert-butyldimethylsilyl)oxy)pheny1)-N ”,N ”-dimethylbenzene-1,4-diamine) (NTPB-2Si), with silyl ether protecting groups were readily synthesized. Subsequently, novel electroactive aromatic poly(ether sulfone)s (PES), NTPPA-PES and NTPB-PES, could be obtained from silyl polycondensation. The PESs were readily soluble in commonly used laboratory organic solvents and could be solution-cast into tough and amorphous films with moderate levels of glass-transition temperature around 220 degrees C and thermal stability without significant weight loss up to 400 degrees C under nitrogen or air atmosphere. The Nernst equation method was used to explore the number of electrons transferred at each oxidation step of the targeted two monomers. Furthermore, these two anodic electrochromic PESs were introduced into electrochromic devices accompanied with cathodic heptyl viologen (HV), and the resulted devices demonstrated a high coloration contrast and excellent electrochemical stability.
