Abstract:
An azobenzene derivative [4‐(6‐oxo‐hexacarboxylic acid)‐3′‐trifluoromethyl‐azobenzene] was synthesized and transferred onto a solid substrate by the Langmuir–Blodgett (LB) technique. The films undergo reversible wettability changes upon irradiation with ultraviolet (UV, 365 ± 10 nm) and visible (436 ± 10 nm) light. This property of reversible wettability of the LB film is confirmed directly by contact angle measurement, UV–Vis absorption spectroscopy and atomic force microscopy (AFM). The results suggest that the wettability change is due to a photoinduced surface energy change. Copyright © 2001 John Wiley & Sons, Ltd.
