Abstract: Anovel mixed Langmuir-Blodgett(LB) film based on a 1:1 (molar ratio) mixture of a new non-amphiphilic tetrathiafulvalene (TTF) derivative dibenzylthio-dimethylthio-te-trathiafulvalene and arachidic acid (AA) was constructed and characterized by FTIR, UVspectra and X-ray diffraction. Measurement of conductivities of the LBfilms relating to the number of layers at room temperature showed that the conductivity of the films decreased with the increasing of layer number. After iodine doping the conductivities of the LBfilms increased by 102-103 magnitude compared with those before iodine doping and reached the maximum 2.5×10-3S/cm due to the formation of a new conducting phase, which was demonstrated by FTIRand UVspectral analyses. The result from X-ray diffraction indicates that the LBfilm has an ordered lamellar structure with a thickness per layer of 2.32nm.

Key words: Tetrathiafulvalene, Non-amphiphilic, Langmuir-Blodgett film, Conductivity
