Herein, we investigate the association of a fullerene fragment, hemifullerene C 30 H 12 , with an electron‐donating bowl‐shaped tetrathiafulvalene derivative (truxTTF). UV/Vis titrations and DFT calculations support formation of the supramolecular complex, for which an association constant of log K a =3.6±0.3 in CHCl 3 at room temperature is calculated. Remarkably, electron transfer from truxTTF to C 30 H 12 to form the fully charge‐separated species takes place upon irradiation of the associate with light, constituting the first example in which a fullerene fragment mimics the electron‐accepting behavior of fullerenes within a supramolecular complex.
