| Outline of Final Research Achievements |
Our research aimed to synthesis of a new series of deuterated functional fullerenes for high performance organic bulk-heterojunction (BHJ) solar cells along with to develop novel catalytic fullerene functionalization reactions. As a result, the use of mono-substituted deuterofullerenes as a new series of electron acceptors for BHJ solar cells improved the power conversion efficiency up to 4.16% which was higher than their protonated fullerene analogues and the standard PC61BM device under the same conditions. Moreover, we have developed various new transition-metal-catalyzed fullerene functionalizations, such as Co-catalyzed highly mono-selective fullerene cycloaddition, Cu-catalyzed C-H amination of hydrofullerenes and Ni-catalyzed direct dibenzylation of fullerene for synthesis of 1,4-difunctional fullerenes.
