Synthesis of liquid crystalline anthraquinolyl–triphenylenes
摘要:
The synthesis, electrochemistry and mesogenic properties of novel anthraquinolyl-triphenylenes are described. H-1 NMR, UV-vis, solution electrochemistry and molecular modelling studies indicate that an intermolecular charge-transfer interaction occurs between the anthraquinone moiety and the triphenylene nucleus.

The synthesis, electrochemistry and mesogenic properties of novel tetrathiafulvalenyl- and ferrocenyl-triphenylenes are described. In all cases the juxtaposition of the hexa-alkyloxytriphenylene with a tetrathiafulvalene or ferrocene unit failed to give rise to derivatives displaying a discotic mesophase. Solution electrochemistry of derivatives 7 and 13 has revealed an interaction occurs between the dicationic state of the TTF moiety and the triphenylene nucleus. (C) 2000 Elsevier Science Ltd.
