Abstract

The photochromism of two 2, 3-diarylbenzo [g] quinoxaline derivatives was explored. Irradiating 2, 3-diphenylbenzo [g] quinoxaline with 350 nm light led to the formation of its photodimer, which could be reverted to its monomers either thermally or photochemically. The resulting photodimer absorbs at a longer wavelength than analogous dianthracene derivatives. 2, 3-Dipyridylbenzo [g] quinoxaline was also observed to undergo ...
