Novel Purely Organic Conductor with an Aminoxyl Radical,alpha-(BEDT-TTF)2(PO-CONHCH2SO3)·2H2O(PO=2,2,5,5-Tetramethyl-3-pyrrolin-1-oxyI Free Radical)

摘要

A novel bis(ethylenedithio)tetrathiafulvalene(BEDT-TTF)-based salt with an aminoxyl radical 2,2,5,5-tetramethyl-3-pyrro-lin-1-oxyl(PO)has been prepared.The salt has alpha-type 2-D conducting sheets and is a semiconductor with rho_(RT)=26 OMEGA·cm and E_a=0.31 eV.The temperature dependence of the magnetic susceptibility suggests that both the aminoxyl radical and the BEDT-TTF layer have local spin moments at room temperature.
