Abstract

The kinetics of thermally driven reactions in a crystalline photochromic solid, 1-methyl-2,4,4,6-tetraphenyl-1,4-dihydropyridine (DHP), has been studied. The processes have been monitored by measuring the isothermal bleaching of coloured species produced upon UV irradiation of DHP, and by measuring the heat flow in non-isothermal differential scanning calorimetry experiments. Signatures of two processes were detected; a combination of quantum-chemical calculations and spectroscopic measurements allowed us to attribute them to reactions occurring in the photochromic system.
