Abstract

Five new metal complexes of 3,3-bis(phenyl)-5-hydroxy-3H-naphtho[2,1-b]pyran with the Pb2+, Zn2+, Ni2+, UO22+, and Tl2+ ions were synthesized. A comparative spectrokinetic study of photochromic transformations of these complexes and uncoordinated naphthopyran was performed. It was shown that the metal complexes exhibit photochromism properties similar to the reversible phototransformations of the precursor. The differences found in the photochromic transformations are explained by the influence of the metal atom on the conjugated bonds and steric changes in the molecule of the complexes.
