Abstract

A Langmuir-Blodgett (LB) thin film deposition technique is used to characterise a novel 1,3-Bis(4-imino-3-hydroxybenzoicacid) indane material on the water surface, and to transfer it as an ultra-thin LB film layer onto solid substrates. Another aim of this work is to study the gas sensing properties of this novel material, using several organic vapors. UV-visible, Atomic Force Microscopy and Quartz Crystal Microbalance results show that a high quality and uniform LB film can be produced using this molecule and the LB film sample is found to be significantly more sensitive to chloroform and benzene vapors than others organic vapors used in this work. The response, in terms of frequency change to the exposure of these vapors, is fast, large and reversible. This material may find potential applications in the development of room temperature organic vapor sensing devices and this newly synthesised indanediimine material has a potential advantage as an LB film material compared to other traditional LB film materials..
