摘要:
Charge-transfer complex formation by a tuning-fork shaped pi-extended tetrathiafulvalene-based molecule, which acts as molecular catcher for C(60) 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 C(60), which leads to a binding constant and lifetime of radical ion pair state of 2.23 x 10(4) (mol L(-1))(-1) and 4.8 ps in ortho-dichlorobenzene.
