The photochromic behavior of an amphiphilic salicylideneaniline derivative, N-(4-dodecoxysalicylidene)-4-carboxyaniline (DSA), incorporated in a Langmuir-Blodgett film was studied.DSA formed a stable and condensed monolayer at an air-water interface, and the monolayer was transferred on quartz substrates.The built-up multilayer was found to possess a highly ordered and densely packed structure.Reversible photochromism of a salicylideneaniline group was observed in built-up DSA films on repeating irradiation with UV light.The rate of the thermal decoloration was proved to be suppressed by the ordered molecular environment in the multilayer.
