Abstract

Abstract : The comparison of the photochromic behaviors of three CPs indicates that metal ions play an important role in regulating their photochromic properties. Abstract : To study the effect of metal ions on the photochromic behaviors of CPs, three new isostructural coordination polymers (CPs) based on a neutral viologen moiety, 1, 1′-bis(3-carboxylatobenzyl)-4, 4′-bipyridinium (bcbpy), have been obtained by choosing 1, 2, 4, 5-benzenetetracarboxylic acid (H4 BTEC) to coordinate with different metal ions, {[M(H2 O)6 ][M(BTEC)(H2 O)4 ]·(bcbpy)·4H2 O} n (M = Co (1 ), Ni (2 ), Zn (3 )), all of which exhibit metal-dependent photochromism and adjustable photosensitivity. Compounds 1 and 2 are only sensitive to UV light, while compound 3 is sensitive to sunlight, UV light and X-ray (Mo). The comparison of the photochromic behaviors of the three CPs indicates that the metal ions play an important role in regulating their photochromic properties.
