ORGANIC PHOTOVOLTAIC DEVICES COMPRISING SUBSTITUTED ENDOHEDRAL METALLOFULLERENES

摘要

Improved organic electronic devices, including, photovoltaic devices, including use of a composition comprising a mixture comprising: (i) at least one p-type material, (ii) at least one n-type material, wherein the n-type material comprises an endohedral metallofullerene derivative represented by: E*-(R)n; and solvates, salts, and mixtures thereof, wherein n is at least one, E* comprises an endohedral metallofullerene having a surface which comprises six-membered and f?ve-membered rings; and R comprises at least one optionally substituted, unsaturated or saturated, carbocyclic or heterocyclic first ring, wherein the first ring directly bonds to the surface of the endohedral metallofullerene. Indenyl derivatization is a preferred embodiment.
