Abstract

Two new anil molecules exhibiting photochromism in the crystalline state, N -(4-hydroxy)-salicylidene-amino-4-(methylbenzoate) ( 2 ) and N -(3,5-di- tert -butylsalicylidene)-4-aminopyridine ( 3 ), are obtained. Upon irradiation in the UV, the yellow crystals change color to red, owing to enol-keto i...
