We have successfully synthesized and separated a series of tert-butyl 4-C61-benzoate (t-BCB) organofullerenes, including monoadduct, diadduct, and triadduct compounds, and investigated their photophysics, electrochemistry, thermal properties, and high-performance liquid chromatography analysis. The photovoltaic devices were fabricated based on monoadduct, diadduct, and triadduct products, and the devices based on them exhibited power conversion efficiencies of 2.43%, 0.48%, and 1.68%, respectively. This was the first time to study the dependent relationship on the device performance and the different isomer numbers.
