A 3D Cycloparaphenylene-Cored Trimeric Electron Acceptor Regulates Acceptor Fibril Morphology for 20.6%-Efficient Ternary Organic Solar Cells.
The application of cycloparaphenylene (CPP) macrocycles in organic photovoltaics has remained largely unexplored despite their unique three-dimensional (3D) topologies. Herein, we expand the functional scope of CPPs by covalently integrating a carbon-nanohoop scaffold with Y-series electron acceptors to develop a novel...
