Abstract
Novel electron-donor molecules based on
tetrathiafulvalene (TTF) and imidazole skeleton with hydrogen-bonded
(H-bonded) functionality 1-5 and 7-10
have been designed and synthesized. The cyclic voltammograms for TTF-based
donors 1-5 exhibit two-stage one-electron reversible
waves, while oligo(imidazole)s 7-10 show irreversible
one. The room-temperature conductivities of their tetracyanoquinodimethane
(TCNQ) complexes for 1, 2, 4, 5,
8 and 9 exhibit 0.11, 0.07, 2.3, 0.38, 0.16 and 0.10
Scm
-1, respectively, revealing high electrical conductivity than those
of known charge-transfer (CT) complexes derived from organic donors with
amino or hydroxyl groups and organic acceptor molecules.
Key words.
TTF, nucleobase, imidazole, hydrogen-bonding,
