Characterization of a novel 1,3-bis-(p-iminobenzoic acid) indane Langmuir-Blodgett (LB) films containing Cd2+ ions in Langmuir-Blodgett (LB) films

Abstract

Newly synthesized 1,3-bis-(p-iminobenzoic acid) indane and 1,3-bis-(p-iminobenzoic acid) indane incorporating Cd2+ films were grown Z-type onto aluminum coated glass substrates by Langmuir-Blodgett film (LB) technique. The transferred 1,3-bis-(p-iminobenzoic acid) indane molecules and the molecules incorporating Cd2+ ions onto substrate were verified by UV-visible absorption spectra and layer by layer growth was confirmed by quartz crystal microbalance (QCM) technique. Electrical properties of the different layered films were investigated by measuring room temperature I-V curves. By analyzing I-V curves and assuming Schottky conduction mechanism the barrier height values have been calculated for LB films with different number of layers.
