Abstract
Benzene-extended derivatives of tetrathiafulvalene (TTF) containing silyl-protected acetylene groups at the exo-cyclic fulvene carbons were prepared by a double Wittig olefination of a diacetylenic derivative of terephthalaldehyde. Acetylenic coupling reactions at the lateral acetylene appendages with phenylacetylene and 4-iodonitrobenzene afforded large π-conjugated chromophores.Keywords
