Threefold exTTF-based Buckycatcher

Charge-transfer complex formation by a tuning-fork shaped π-extended tetrathiafulvalene-based molecule, which acts as molecular catcher for C60 in a variety of solvents upon photoexcitation, has been explored. An increase in 2-[9-(1,3-dithiol-2-ylidene)anthracen-10(9H)-ylidene]-1,3-dithiole unit creates an easy-chair like conformation accommodating C60, which leads to a binding constant and lifetime of radical ion pair state of 2.23 × 104 (mol L−1)−1 and 4.8 ps in ortho-dichlorobenzene.
