A cobalt-catalyzed cyclotrimerization of bis(aryl)alkyne is used as an innovative tool to obtain hole-transport materials (HTMs). The novel HTM containing six units of oligotriarylamine (HAB1), characterized by UV-vis, cyclic voltammetry, DFT, and thermogravimetric analysis, confirms its suitability as an efficient HTM in PSCs. A PCE of 17.5% was obtained in HAB1-containing PSCs, a performance comparable to that obtained with spiro-OMeTAD and with slightly better thermal stability.

A mixture DMSO-allyl bromide has been developed as a reagent for an atom economic one-pot N-allylation and aryl bromination under basic conditions. Utilizing this reagent, N-allylation-bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction mechanism have been proposed.

Paragraph 0539-0543, (2020/04/10)
The present invention relates to a pyrene based derivative compound of an asymmetric structure and an organic electroluminescent device comprising the same. The pyrene derivative according to the present invention is characterized by being represented by chemical formula A through chemical formula B. The pyrene derivative compound according to the present invention exhibits remarkably improved blue color purity as compared to an organic electroluminescent device using an existing pyrene based aryl amine derivative compound while being able to realize full color since life characteristic and luminance characteristic are excellent, thereby being able to be used in various display devices.
