RT Journal Article T1 Cyclobuteno[60]fullerenes as efficient n-type organicsemiconductors A1 Reboredo, Silvia A1 Girón, Rosa M. A1 Filippone, Salvatore A1 Mikie, Tsubasa A1 Sakurai, Tsuneaki A1 Seki, Shu A1 Martín, Nazario AB 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 PCBM, thus behavi ng as promising n-type organic semiconductors.
