Abstract

A detailed spectroscopic study of photoinduced and thermally activated proton-transfer processes for a series of different crystals of 2-(2, 4-dinitrobenzyl) pyridine derivatives has been performed. The quantitative analysis of ground-and excited-state activation barriers and preexponential factors in deuterated and nondeuterated crystals shows clearly that the observed photochromism is linked to a proton-transfer process. Furthermore, it is clearly ...
