Organic Solar Cells (OSCs) have attracted considerable interest because of their light weight, mechanical flexibility and nontoxicity. The conventional photoactive layer is composed of a polymer or small-molecule donor and a fullerene acceptor. But due to intrinsic limitations of fullerenes, Non- Fullerene Acceptors (NFAs) have been largely explored in recent years. Among them, the iconic perylenediimide (PDI) derivatives present superior light- harvesting capabilities yielding higher photocurrent, readily tunable optical and electrochemical properties. All polymer solar cells (all-PSCs) that utilize conjugated polymers as both the electron-donor and electron-acceptor offer several unique superiorities including excellent morphological stability and mechanical flexibility. Thus PDI-based all-PSCs are believed to be one of the most promising candidates because PDI derivatives present the best trade- off Efficiency, Cost and Stability suitable for industrial scale-up. The DisPol-PDI project aims at investigating the use of nitroarenes as electrophiles in organometallic cross-coupling reactions, a so far very poorly explored area despite its high potential and availability. Our recent results on Suzuki-Miyaura Coupling carried out on mono and dinitro bay-substituted PDIs promise a bright future for such methodology. In particular, this cross- coupling reaction has demonstrated a unique selectivity opening the route to an unprecedented bay-desymmetrization of the PDI backbone. In this context, this DisPol-PDI project aims at exploring a new design of polymer architectures using this desymmetrization strategy to reach original polymers.
