‘Organic metals’: alkylthio substitution effects in tetrathiafulvalene–tetracyanoquinodimethane charge-transfer complexes

Abstract
The synthesis and diverse conductivity properties of the tetracyanoquinodimethane (TCNQ) complexes of several tetrakis-(alkylthio)-tetrathiafulvalenes are described, and compared with those of tetrathiafulvalene-TCNQ and related complexes.
