Synthesis and Characterization of a Methanofullerene-4-Fluoro-α-Cyanostilbene Dyad as a Potential Acceptor for Organic Solar Cells
Published online by Cambridge University Press: 17 June 2015
Abstract
A series of fluorine appended highly conjugated fullerenes were prepared containing fluoro-α-cyanostilbene and aryl ester units. These modified PCBM dyads are fully characterized by NMR, Mass spectrometry, UV-vis, and cyclic voltammetry (Figures 1-4). It was found that the presence of fluoro-α-cyanostilbenes and esters affects the cyclic voltammetry and absorption in the UV-Vis region. The PCBA modified fullerenes significantly influences the HOMO-LUMO energy and wide absorption compared to PCBM.
