Role of the order on the kinetic behaviour of photochromic guest molecules
Abstract An investigation of ring closure reaction of two photochromic spiropyrans with different ń‐alkyl chain lengths in liquid crystal solvent and DML vesicle solution is reported. The temperature dependence of In k was determined in these media. Arrhenius plots for both compounds show a sharp se...
