7,7,8,8-Tetra(2-thienyl)-p-quinodimethanes. New Electron-Donating p-Quinodimethanes

Tetra(2-thienyl)-p-quinodimethanes, a new family of electronrich p-quinodimethane, show good amphoteric redox properties: in particular, the tetrakis(methylthio) derivative is an excellent electron-donor to form charge transfer complexes of good electrical conductivity.
