Tetrafluoro and dichloro derivatives of thiophene-fused DCNQI- and TCNQ-type acceptors: a synthetic, electrochemical and crystallographic study
Abstract
Novel thiophene-fused DCNQI derivatives8 and 11
bearing four fluorine atoms have been obtained in good yield from the
corresponding quinones by reaction with bis(trimethylsilyl)carbodiimide
(BTC). The presence of four fluorine atoms leads to good acceptor
molecules which form charge transfer complexes in solution with
N,N′-tetramethyl-p-phenylenediamine. The
effect of chlorine atoms on the crystal packing in the analoguous
thiophene-fused TCNQ derivatives 3a and 3b is also
reported.
