摘要：
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 photoisomerisation of this compound in solutions and in Langmuir-Blodgett multilayers has been observed on irradiation with alternating UV (360nm) and visible (450nm) light. The reversible changes of absorbance of main absorption band and surface potential of Langmuir-Blodgett multilayers on alternate irradiation is demonstrated.
