title: Modification of the σ-framework of [60]fullerene for bulk-heterojunction solar cells.
abstract: Modification of the σ-framework of [60]fullerene has been shown to be a new avenue toward n-type materials for bulk-heterojunction solar cells. This approach allowed distinct control of the LUMO level of the C(60)π-system and resulted in a clear improvement of an open-circuit voltage.
