Abstract
Langmuir-Blodgett (LB) multilayers prepared from methyl-acylamino-azob enzene derivatives have been investigated. Reversible transl cis photo isomerisation of yl-N-4-[4-(methyl-palmitoylamino)phenylazo]benzoyl u rea in LB films has been observed on alternate irradiation with UV (36 0 nm) and visible (450 nm) light. Anisotropy in the electrical conduct ivity of LB multilayers was observed. The electrical conductivity thro ugh the sample (bulk conductivity) was of the order of 10(-10) S cm(-1 ). In the case of in-plane samples the conductivity is higher by sever al orders. The charge carrier trapping states in the energy gap of LB multilayers were deduced.
