Excellent Reversible Photochromic Behavior of 4-Octyl-4′-(5-carboxylpentamethyleneoxy)-azobenzene in Organized Monolayer Assemblies

Zhongfan Liu, Boon Hian Loo, Ryo Baba, Akira Fujishima

Abstract

Abstract We report the first observation of a photochromic behavior of an amphiphilic azobenzene derivative in the close-packing LB films on a solid support. The excellent reversibility was achieved only after the LB films were ‘pretreated’ with UV irradiation.
