Cyclobuteno[3,4:1,2][60]fullerenes have been prepared in a straightforward manner by a simple reaction between [60]fullerene and readily available allenoates or alkynoates as organic reagents under basic and mild conditions. The chemical structure of the new modified fullerenes has been determined by standard spectroscopic techniques and confirmed by X‐ray diffraction analysis. Some of these new fullerene derivatives exhibit a remarkable intrinsic electron mobility (determined by using flash‐photolysis time‐resolved microwave conductivity (FP‐TRMC) measurements), which surpasses that of the well‐known phenyl‐C61‐butyric acid methyl ester, thus behaving as promising n‐type organic semiconductors.
