Synthesis and characterization of novel strong electron acceptors: bithiazole analogues of tetracyanodiphenoquinodimethane (TCNDQ)
摘要:
Novel electron accepters, bithiazole analogues of tetracyanodiphenoquinodimethane (TCNDQ), were synthesized by using a Pd-catalyzed coupling reaction of a dibromated precursor with sodium dicyanomethanide. The new accepters show strong electron-accepting ability and small on-site Coulomb repulsion. The X-ray crystallographic analysis has revealed a planar structure containing a double bond with E-configuration. Several charge transfer complexes were obtained with electron donors such as tetrathiafulvalene (TTF), (C) 2000 Elsevier Science Ltd. All rights reserved.
