Abstract

A new tetrathiafulvalene(TTF) derivative - 4,5-bismethylthio-4',5'-bis(3-picolylthio)-tetrathiafulvalene (BMP-TTF) bearing pyridine groups was found to form stable monolayers at the air/water interface with or without the presence of AgNO 3 . The monolayers can be transferred onto solid substrates with LB technique. Surface pressure-area isotherms, UV-vis spectrum, FT-IR, X-ray photoelectron spectroscopy. and X-ray diffraction were used to characterize the monolayer formation and the transferred LB films. The room temperature conductivities of the LB films are about ∼10 -7 S.cm -1 and after iodine doping, they are increased to ∼10 -3 S.cm -1 .
