Tris-fused tetrathiafulvalenes, TTCn-TTPY (n = 2-5) have been prepared, and the structural and conducting properties have been investigated. The neutral crystals of TTCn-TTPY exhibit low electrical resistivity as a neutral organics; the lowest is 80 Ωcm in TTC2-TTPY. When TTCn-TTPY is exposed to iodine vapor, the sample becomes highly conducting in a few minutes, but again becomes insulating on account of overdoping. When taken out from the iodine atmosphere, the high conducting state is recovered, and the high conducting sample shows metallic conductivity and thermoelectric power down to helium temperatures.
