Abstract
Several derivatives of alkyl-substituted DTEDT have been synthesized. Single crystals of cation radical salts of dimethyl-DTEDT (1Ab) with o ctahedral anions showed high conductivities (sigma(rt)=10(0)-10(1)Scm( -1)) and metal-like behavior around room temperature. The metal to ins ulator transition temperature tends to decrease as the volume of anion s increases. The PF6, AsF6 salts of cyclopenteno-DTEDT (1Ac), and TaF6 salt of tetramethyl-DTEDT (1Bb) show metallic conducting behavior dow n to 50 K.
