Abstract
Official abstract text for this publication.
1,4 fullerene deriatives useful for solar cells are provided, where their structures allow for straightforward functionalizations to tune their properties in terms of solubility and LUMO energy levels.
First claim
Opening claim text (preview).
The invention claimed is: 1. A photovoltaic cell comprising a 1,4 fullerene derivative having the formula: wherein: the fullerene comprises at least 60 carbon atoms; at least one of R1-R10 is hydrogen; and at least one of R1-R10 is independently selected from alkyl, aryl, amino, oxo, thio, alkyl, halogen, and silanes; wherein the derivative is selected from the gro…
