Molecular design approach of increasing the triplet energy of host materials using pyrrole as a core structure

We developed and synthesized 9,9′-(1-phenyl-1H-pyrrole-2,5-diyl)bis(9H-carbazole) (PPyCz2) as a hole transport type high triplet energy host material for blue phosphorescent organic light emitting diodes. We approached the molecular design by inserting a pyrrole moiety to prevent extension of conjugation of molecule and achieved a high triplet energy of 2.99 eV in the PPyCz2 host. Furthermore, the PPyCz2 host showed a high external quantum efficiency of 14.8% in blue phosphorescent organic light emitting diodes.

Organic semiconductor photocatalyst can bifunctionalize arenes and heteroarenes

Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two- or three-component system for direct twofold carbon–hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

A novel and convenient method for the preparation of 5-(diphenylmethylene)-1H-pyrrol-2(5H)-ones; synthesis and mechanistic study

An efficient, regioselective synthesis has been developed for the preparation of 5-(diphenylmethylene)-1H-pyrrol-2(5H)-ones from readily available 1H-pyrroles by sequential dibromination and selective organometallic bromine/lithium exchange followed by reaction with benzophenone. Comparison of various N-substituents was shown to demonstrate the high tolerance of the transformation to functional groups. The structures of the new products were determined by spectroscopic methods and confirmed by single-crystal X-ray diffraction measurement. In addition, theoretical study of the reaction mechanism and selective functionalization of the endocyclic double bond were also presented.

Influence of electron delocalization in heterocyclic core systems on the electrochemical communication in 2,5-Di-and 2,3,4,5-tetraferrocenyl thiophenes, furans, and pyrroles

A series of 2,5-di-and 2,3,4,5-tetraferrocenyl-substituted thiophenes, furans, and pyrroles were synthesized using the Negishi C,C cross-coupling protocol. The electronic and electrochemical properties of these compounds were investigated by cyclic voltammetry (CV), square wave voltammetry (SWV), and in situ UV-vis/NIR spectroscopy. The molecular structures of 2,5-diferrocenyl furan and 2,3,4,5-tetraferrocenyl-1-methyl-1H-pyrrole in the solid state are discussed. The ferrocenyls could sequentially be oxidized giving two or four reversible responses for the appropriate di-or tetraferrocenyl-substituted heterocyclic molecules. The observed ΔE°′ values range between 186 and 450 mV. The NIR measurements confirm electronic communication as intervalence charge transfer (IVCT) absorptions were found in the corresponding mono-and in case of the tetraferrocenyl compounds also in the dicationic species. All compounds, except tetraferrocenyl thiophene (a class I system), were classified as class II systems according to Robin and Day. They show a linear relationship between ΔE°′ and the IVCT oscillator strength f which could be shown for the first time in organometallic chemistry. This was possible because the series of molecules exhibit analogous geometries and hence, similar electrostatic properties. This correlation was confirmed by electro-and spectro-electrochemical measurements. Within these studies a new approach for the estimation of the effective electron transfer distances r ab is discussed.

Bromination and Chlorination of Pyrrole and Some Reactive 1-Substituted Pyrroles

Monobromination of pyrrole and 1-methyl-, 1-benzyl-, and 1-phenylpyrrole with 1 mol of N-bromosuccinimide in tetrahydrofuran results in the regiospecific formation of the 2-bromopyrroles.A little disubstitution is observed.Similarly, brominations with 2, 3, or 4 mol of NBS form primarily the di-, tri-, and tetrabromopyrroles, respectively.The thermodynamically more stable 3-bromopyrroles are the major monobrominated products observed when bromine is used as the brominating agent due to isomerization of the 2-bromopyrroles with hydrogen bromide.These reaction mixtures are further complicated because of disproportionation reactions.Chlorination with N-chlorosuccinimide gave results similar to those for the bromination with NBS, but the reaction is not as selective.
