Effective tuning of the electronic and photophysical properties of tetrathiafulvalene pyrroles via aromatic heterocycle annulation

We report the synthesis and characterization of a series of fused molecular triads, consisting of tetrathiafulvalene-pyrrole derivatives annulated with pyrrole, benzene, thiophene, furan, pyrazine and thiadiazole. Unique and readily tunable optical and electrochemical features are displayed by these new systems.
