Photoluminescence of melanin-based nanocomposites with fullerene derivative

This paper presents the study of photoluminescent properties molecular compositions consisting melanin and an electron-acceptor material – fullerene derivative, [6,6]-phenyl C61 butyric acid methyl ester (PCBM). These have not been studied well are promising for electronics natural materials, in particular, organic solar cells. The novelty this work relates to photoluminescence spectra obtained these nanocomposites various solvents (chloroform, acetonitrile, toluene) as a polystyrene matrix; studies were carried out at various, liquid helium (4.2 K), temperatures. results allowed us ascertain mechanisms state aggregation donor-acceptor interaction between PCBM.
