Abstract

We have synthesized and investigated a novel electrondonor -- electronacceptor type photoactive amphiphilic azobenzene derivative containing the hydrophobic dicyclohexylamine moiety along with the hydrophylic carboxyl group at the opposite end of the molecule. Reversible trans/cis photoisomerization of this compound in solutions and in Langmuir-Blodgett multilayers has been observed on irradiation with alternating UV (360 nm) and visible (450 nm) light. The reversible changes of absorbance of main absorption band and surface potential of Langmuir-Blodgett multilayers on alternate irradiation is demonstrated.
