Abstract

Corresponding to the humidity, a transparent and metallically conductive polycarbonate thin film, at the surface of which micro-crystals of (bis(ethylenedioxy)tetrathiafulvalene)₂Br(H₂O)₃ were embedded, showed quasi-reversible modulation of inter-conducting-layer distance in the micro-crystals and the surface resistance of the film. The best surface conductivity was observed at the relative humidity of ca. 10%. At the relative humidity of 5.4–8.6%, the coexistence of two kinds of structures of the micro-crystals having different interlayer distances was detected. Both of them showed humidity dependent electrical and structural modulations.
