Developing cost-effective and rational hole transporting materials is critical for fabricating high-performance perovskite solar cells (PSCs) and to promote their com. endeavor. We have designed and developed pyridine (core) bridging diphenylamine-substituted carbazole (arm) small mols., named as 2,6PyDANCBZ and 3,5PyDANCBZ. The linking topol. of core and arm on their photophys., thermal, semiconducting, and photovoltaic properties were probed systematically. We found that the 2,6PyDANCBZ shows higher mobility and conductivity along with uniform film-forming ability as compared to 3,5PyDANCBZ. The PSCs fabricated with 2,6PyDANCBZ supersede the performance delivered by Spiro-OMeTAD and importantly also gave improved long-term stability. Our findings put forward small mols. based on core-arm linking topol. for cost-effective hole selective layers designing.

An extensive kinetic study of selected key reactions of (oxidative) gold catalysis concentrates on the decrease of the catalytic activity due to inhibition of the gold(I) catalyst caused by pyridine derivatives that were obtained as byproducts if N-oxides are applied as oxygen donors. The choice of the examined pyridine derivatives and their corresponding N-oxides has been made regardless of their com. availability; particular attention has been paid to the practical benefit which up to now has been neglected in most of the reaction screenings. The test reactions were monitored by GC and 1H NMR spectroscopy. The received reaction constants provide information concerning a correlation between the electronic structure of the heterocycle and the catalytic activity. Based on the collected kinetic data, it was possible to develop a basic set of three N-oxides which have to be taken into account in further oxidative gold(I)-catalyzed reactions.

The author of the article were Xu, Xiaowen; Van Guyse, Joachim F. R.; Jerca, Valentin Victor; Hoogenboom, Richard. The article conveys some information:

The design and synthesis of polymer-based metallomacrocycles relying on metal-ligand interactions remain a challenge in the polymer field. Instead of utilizing chem. reactions to synthesize macrocycles, a general approach is proposed to construct metallomacrocyclic structures through supramol. self-assembly of a specific macroligand with suitable transition metal ions. Therefore, a new ditopic macroligand (L) consisting of PEG end-capped with 2,6-bis(1,2,3-triazol-4-yl)pyridine derivatives is prepared via CuAAC “”click”” reaction. Four types of metal (Fe2+, Zn2+, Ni2+, and Cu2+) complexes are obtained by simply mixing a solution of metal ions and L in appropriate concentrations The investigation of the coordination chem. suggests that coordination of L with Cu2+ results in the formation of a [1+1] metallomacrocycle, while the other metal complexes exclusively lead to the formation of linear metallopolymers and/or larger aggregates. This work provides new insights into designing metallomacrocycles and may have potential application in the synthesis of catenanes and other cyclic or cycle-based topol. architectures.

New palladium complexes were efficiently synthesized from the reaction of benzimidazolium salts 2a-e, potassium carbonate (K2CO3) and palladium chloride (PdCl2) in pyridine (for 3a-e). The catalytic activity of these complexes in a catalytic system including palladium complexes and K2CO3 in DMF-H2O was evaluated in Suzuki-Miyaura cross-coupling reactions of aryl bromides and chlorides with phenylboronic acid. The authors’ novel complexes show excellent catalytic activities with high turnover numbers (TON) and high turnover frequencies (TOF) (e.g. for the Suzuki-Miyaura reaction: TON up to 370 and TOF up to 123.3 h-1). Both benzimidazolium salts 2a-e and complexes 3 were characterized using spectroscopic data and elemental anal. The antimicrobial activity of the N-heterocyclic carbene palladium complexes 3a-e varies with the nature of the ligands. Also, the IC50 values of both, complexes (3a-e) and benzimidazoles 2a-e, were determined The new palladium complexes were screened for their antitumor activity.

Computed Properties of C5H3Br2N The article mentions the following:

A series of charge-neutral bis-tridentate Ir(III) complexes (1, 3, and 4) were prepared via employing three distinctive tridentate prochelates, i.e., (pzptBphFO)H2, [(phpyim)H2·(PF6)], and [(pimb)H3·(PF6)2], which possess one dianionic pzptBphFO, together with a second monoanionic tridentate chelate, namely, (pzptBphFO)H, phpyim, and pimb, resp. Moreover, a homoleptic, charge-neutral complex 2 was obtained by methylation of chelating (pzptBphFO)H of 1 in basic media, while closely related cationic complexes 5-7 were obtained by further methylation of the remaining pyrazolate unit of previously mentioned neutral complexes 2-4, followed by anion metatheses. All of these Ir(III) metal complexes showed a broadened emission profile with an onset at ∼450 nm, a result of an enlarged ligand-centered ππ* transition gap, but with distinct efficiencies ranging from 0.8% to nearly unity. Comprehensive spectroscopic and computational approaches were executed, providing a correlation for the emission efficiencies vs. energy gaps and between the metal-to-ligand charge transfer/ππ* emitting excited state and upper-lying metal-centered dd quenching state. Furthermore, Ir(III) complexes 3 and 4 were selected as dopant emitters in the fabrication of sky-blue phosphorescent organic light-emitting diodes, affording maximum external quantum efficiencies of 16.7 and 14.6% with CIEx,y coordinates of (0.214, 0.454) and (0.191, 0.404) at a c.d. of 102 cd/m2, resp. Hence, this research highlights an inherent character of bis-tridentate Ir(III) complexes in achieving high phosphorescence quantum yield at the mol. level.

The article was titled 《Multidentate, V-Shaped Pyridine Building Blocks as Tectons for Crystal Engineering》.Name: 2,6-Dibromopyridine The article contains the following contents:

The formation of supramol. structural units through self-assembly is a powerful method to design new architectures and materials endowed with specific properties. With the aim of adding a group of versatile tectons to the toolkit of crystal engineers, 4 new V-shaped building blocks characterized by an aryl acetylene scaffold comprising 3 substituted pyridine rings connected by 2 triple bonds were have devised and synthesized. The judicious choice of different substituents on the pyridine rings provides these tectons with distinctive steric, electrostatic and self-assembly properties, which influence their crystal structures and their ability to form co-crystals. Co-crystals of the tectons with tetrafluorodiiodobenzene were obtained both via traditional and mechanochem. crystallization strategies, proving their potential use in crystal engineering. The energetic contributions of the supramol. interactions at play in the crystal lattice also were evaluated to better understand their nature and strength and to rationalize their role in designing mol. crystals.
