摘要

The tendency to phase segregation in blends of C_(60) derivatives and conjugated polymers has to be optimized to improve both charge photogeneration and transport in photovoltaic devices. In this communication we present two approaches in order to tailor the phase separation in organic films: (ⅰ) the first approach involves the synthesis of functionalized C_(60) derivatives with enhanced solubility; (ⅱ) the second approach is directed to the synthesis of systems containing a π-conjugated moiety antenna covalently linked to the C_(60) unit. Together with the synthesis of these new materials, electrochemical and photophysical investigations have been also carried out. Photovoltaic devices have been fabricated with selected materials.
