Abstract
The acid-gated photochromism and the photomodulation of fluorescence and proton affinity of a novel dimethylaminophenyl thiazole diarylethene in MeCN were investigated from a kinetic point of view. Photomodulation of the proton affinities has been estimated from acid titrations and numerical modelling of the acid induced T-photochromism. The basicities of the thiazole and dimethylamino protonation sites are different by only one pK unit. Upon ...
