摘要：

Some new photoresponsive azobenzenes (1-5) have been synthesized and characterized. On irradiation at 330 nm these systems undergo conversion from the E to the Z form to a varying extent which depends upon the nature and position of substitution on the azobenzene rings. They revert back to the E form on thermal isomerization in the dark. Photochemical equilibria have been studied and compared in acetonitrile and o-dichlorobenzene; E forms are stabilized more in o-dichlorobenzene than in acetonitrile. Two of the molecules (1 and 4) show enhanced transport of CU2+ ions across a liquid membrane on irradiation.
