Abstract
Studies have been made of alternate layer (ABABA superlattices) multilayer Langmuir–Blodgett (LB) films using a cyclic polysiloxane (A) and an iridium(I) polyalkoxystilbazole metallo-organic complex (B). The electrically polar nature of the molecules studied suggests that they may be suitable candidates for new pyroelectric materials. The pyroelectric coefficient has been measured for alternate layer multilayer LB films built with various number of layers of the iridium(I) complex. We investigate the effect of chain length of the substitution and position of the substitution on the pyroelectric coefficient, capacitance and dielectric loss.
