Photoinduced electron-transfer systems consisting of electron-donating pyrenes or anthracenes and benzimidazolines for reductive transformation of carbonyl compounds
摘要:
Photoinduced electron-transfer reactions of several ketone substrates were studied to evaluate the utilities of 1,6-bis(dimethyl-amino)pyrene (BDMAP), 1,6-dimethoxypyrene (DMP), 9,10-bis(dimethlylamino)anthracene (BDMAA), and 9,10-dimethoxyanthracene (DMA) as electron-donating sensitizers cooperating with 2-aryl-13-dimethylbenzimidazolines. BDMAP and DMP generally led higher conversion of ketones and better yield of reduction products compared to BDMAA and DMA. (c) 2006 Elsevier Ltd. All rights reserved.

Anthracene derivatives each having a structure including an anthracene skeleton, a phenanthrene skeleton selected from among various phenanthrene skeletons different in bonding site which is bonded to the 9-position of the anthracene skeleton and a group selected from among various aryl groups and so on which is bonded to the 10-position of the anthracene skeleton. Organic EL devices made by using the derivatives exhibit high light emission efficiency and a long life.
