Abstract
A novel mixed Langmuir-Blodgett(LB) film based on a 1:1 (molar ratio) mixture of a new non-amphiphilic tetrathiafulvalene (TTF) derivative d ibenzylthio-dimethylthio-tetrathiafulvalene, and arachidic acid(AA) wa s constructed and characterized by FTIR, UV spectra and X-ray diffract ion. Measurement of conductivities of the LB films relating to the num ber of layers at room temperature showed that the conductivity of the films decreased with the increasing of layer number, After iodine dopi ng the conductivities of the LB films increased by 10(2) similar to 10 (3) magnitude compared with those before iodine doping and reached the maximum 2.5x10(-3) S/cm due to the formation of a new conducting phas e, which was demonstrated by FTIR and UV spectral analyses, The result from X-ray diffraction indicates that the LB film has an ordered lame llar structure with a thickness per layer of 2.32 nm.
