چکیده انگلیسی
In this work calix [4] acid (A) has been deposited alternately with calix [4] amine (B) using the LB film deposition technique to form a non-centrosymmetric ABABA⦠molecular architecture. Pyroelectric and dielectric electric measurements have been performed for a 31 layer calix [4] acid/amine alternate layer LB film. Pyroelectric coefficients for this LB film system have been obtained using a quasi-static measurement system. Dielectric measurements have been used to determine the dielectric constant and the dielectric loss tangent. The data obtained from pyroelectric and dielectric measurements have been used to calculate the figure of merit for these LB film systems which has a value of 2.56 μC mâ2 Kâ1.
