Enclathrated Solvent Effects on the Photochromic Process of N-Salicylideneaniline in the Crystal State

N-{3,5-bis(1-methyl-1-phenylethyl)salicylidene}-4-tritylaniline and its clathrate crystals with methanol and acetone were prepared. Solvent effects were observed on the solid-phase photoisomerization of the Schiff base.
