Abstract
The new organic π-donor, 2-(thiopyran-4-ylidene)-1,3-dithiole (3), iso-π-electronic to both tetrathiafulvalene (1) and Δ4,4′-bithiopyran (2) and obtained by a three-step synthesis in 15% overall yield, reacts with 7,7,8,8-tetracyanoquinodimethane (TCNQ) to give two semiconducting salts.Keywords
