Research Abstract

Hydrogen-bonded purely organic single-component (unit) molecular conductors based on tetrathiafulvalene (TTF)-type organic pi-electron donor molecules fused with hydrogen-bonding functional groups were synthesized and characterized. Interestingly, the conductivity of the catechol-fused TTF-based single-unit organic conductor system is enhanced by the substitution of its hydrogen-bonded proton with deuteron, although the parent and deuterated systems are isostructural each other at room temperature.
