NEW ANGULAR MOLECULAR DONOR CONTAINING 2 TETRATHIAFULVALENE (TTF) UNITS FUSED TO SELENOPHENE - SYNTHESIS, X-RAY STRUCTURE, CYCLIC VOLTAMMETRY AND CONDUCTING CHARGE-TRANSFER COMPLEX WITH TCNQ

Communication: Extended TTF-based donor systems based for the first ti me on selenophene (see Fig.) are reported. Selenophene is an isologue of thiophene but has a stronger electron-donating ability, a larger si ze, and a higher polarizability. These factors should lead to material s with increased bandwidth, improved dimensionality, increased electri cal conductivity, and reduced on-site Coulombic repulsion. The one-pot synthesis of these materials and their complexation with TCNQ are pre sented.
