ABSTRACT
Zinc complexes composed of bidentate 1,2-bis(2-methyl-5-(4-pyridyl)-3-thienyl)perfluorocyclopentene ( 1a ) or monodentate 1-(2-methyl-5-phenyl-3-thienyl)-2-(2-methyl-5-(4-pyridyl)-3-thienyl) perfluorocyclopentene ( 2a ) photochromic ligands and Zn(hfac)2 or ZnCl2 were prepared and their photochromic properties were studied.
