Ultra thin organic films, (3-docosyl benzimidazolium)-TCNQ(1:1)complex, were deposited onto ordinary microscope slide glass substrates with a Langmuir-Blodgett technique. II-A isotherms were studied to find optimum conditions of deposition by varying temperature. Anisotropic de electrical conductivities were measured at room temperature. They are about 5.21×10-12S/cm along the direction of film surface, and (2.73~4.40)×10-16S/cm in the vertical direction.

A Stability to the Spreading solvents, Which is acetonitrile, dichloromethane, benzene, chloroform and acetonitrile-benzene(1:1, v/v) of (3-Alkyl benzimidazolium)-TCNQ(1:1) Complex was investigated by UV-visible Spectrometer and was confirmed stabilized on acetonitrile, acetonitrilbenzene(1:1, v/v) for five hours. Using Ultra pure water as subphase for Langmuir-Blodgett (LB) Films, it was achived successively to fabricate the Y-type LB films of (3-Alkyl benzimidazolium)-TCNQ(1:1) Complex.

In this research, (3-alkyl benzimidazalium)-TCNQ complexes were synthesized to obtain the necessary components for Langmuir-Blodgett Technique. (3- Alkyl benzimidazolium)-TCNQ complexes were prepared by the reaction of LiTCNQ with 3-alkyl benzimidazolium bromides and the products were confirmed by elemental analysis. FT-IR, UV-Visible spectroscopies. FT-IR spectra of (3-alkyl benzimidazolium) TCNQ(1:2) complexes were characterized by a broad band with a maximum at about 2900cm-1 appears and were ascribed to electronic rather than vibrational absorption.
