Abstract
N-bridged PCBMs are prepared by the cycloaddition of an organic azide to C60. The N-bridged PCBMs are imino PCBMs, exemplified by an isomeric mixture of [5,6]-open APCBM and [6,6]-closed APCBM. An organic electronic material containing a fullerene adduct, such as an organic field effect transistor or an organic photovoltaic device, is provided containing the N-bridged PCBM as the fullerene adduct.
Claims14
A method for preparing N-bridged PCBMs, comprising reacting an organic azide with C60 by cycloaddition to produce at least one N-bridged PCBM.
An organic electronic device comprising at least one N-bridged PCBM.
An imino PCBM selected from the group consisting of [5,6]-open APCBM, [6,6]-closed APCBM, and an isomeric mixture thereof.
