A Covalent Tetrathiafulvalene-Tetracyanoquinodimethane Diad: Extremely Low HOMO-LUMO Gap, Thermoexcited Electron Transfer, and High-Quality Langmuir-Blodgett Films

Nearly 30 years after theoretical prediction, a stable and well‐characterized compound that covalently links tetrathiafulvalene and tetracyanoquinodimethane fragments has been synthesized (1, see scheme). The extremely low HOMO–LUMO gap of 1 (0.17 eV) allows the first observation of thermoexcited el...

Description
Summary:Nearly 30 years after theoretical prediction, a stable and well‐characterized compound that covalently links tetrathiafulvalene and tetracyanoquinodimethane fragments has been synthesized (1, see scheme). The extremely low HOMO–LUMO gap of 1 (0.17 eV) allows the first observation of thermoexcited electron transfer in a donor–acceptor diad. Langmuir–Blodgett films of 1 are not electrically conducting.
