Efficient photochemical switching of metal-ion complexation by Malachite Green leuconitrile derivatives carrying bis(crown ether)

A Malachite Green derivative incorporating a bis(monoazacrown ether) structure enables efficient photocontrol of metal ion complexation. Its photochromism in the presence of alkali metal ions is examined by kinetics measurements and molecular-orbital (MO) calculation.

Metal-ion complexation and photochromism of triphenylmethane dye derivatives incorporating monoaza-15-crown-5 moieties

Three types of triphenylmethane leuconitrile derivatives incorporating one, two, and three monoaza-15-crown-5 moieties have been designed to attain photocontrol of metal-ion complexation primarily by intramolecular electrostatic repulsion. Photochromism o
