摘要：

Cation complexation of a 2,2-bis((N,N-dimethylamino)phenyl)-2-phenylmethanenitrile (Malachite Green leuconitrile) derivative carrying a 15-crown-5 moiety affects its photochromic ionization remarkably. The crowned Malachite Green leuconitrile can afford photochemical cation-complexing control of its crown moiety; photoionization of the crowned Malachite Green to its triphenyl or quinoid cation suppresses cation complexation of the crown moiety mainly due to the intramolecular electrostatic repulsion. Applications of the crowned Malachite Green to ion-conducting materials indicate that the photochemical control of cation-complexing ability is reflected in the ionic-conductivity switching of composite films containing the photochromic crown compound and a sodium salt.
