Synthesis and nanostructures of several tetrathiafulvalene derivatives having the side chains composed of chiral and hydrogen-bonding groups and their charge-transfer complexes

Abstract

Tetrathiafulvalene (TTF) derivatives TTF-Bor, TTF-2UM and TTF-4UM having chiral urethane groups were prepared. Among them, TTF-2UM, TTF-4UM and their charge-transfer (CT) complexes with F4TCNQ organized the nanowires. The intermolecular hydrogen bonding of the chiral urethane groups and π-stacking of TTF moieties or the formation of CT complexes resulted in a long one-dimensional nanowires. The chiral moieties were responsible for the molecular orientation of TTF cores to give helical structures. Electronic conductivity of the films of nanowires composed of TTF-2UM and TTF-4UM with F4TCNQ were determined to be 8.0 × 10−2 and 3.2 × 10−2 S cm−1, respectively.
