Triadic intramolecular charge transfer compound of tetrathiafulvalene exhibiting multicolor solvatochromism.


An A-D-A triad compound comprising a tetrathiafulvalene (TTF) moiety and two pyridyl groups, py-TTF-py (1), has been studied in view of intramolecular charge transfer (ICT). The compound shows a sharp and multicolor change in different solvents and at different pH values, exhibiting good solvatochromism. The results of electronic absorption spectroscopy… (More)
