Since the discoveries of an organic metal by a TTF-TCNQ complex in 1973 and of an organic superconductor by a PF₆ salt of TMTSF radical cation in 1979, respectively, TTF and its derivatives continue to play a crucial role in the development of new organic conductors, especially organic superconductors with higher Tc. In addition, TTF and its derivatives are expected as key molecules for the development of single component organic metals, the material systems in coexistence of conducting π electrons and localized d or π spins, high spin systems, and infrared absorption materials. The present review mainly present our results on new TTF derivatives synthesized with aim at other novel magnetic, optical, magnetic/electrical properties than electrical conductivity.
