Open AccessLimiting factors for charge generation in low-offset fullerene-based organic solar cells
Free charge generation after photoexcitation of donor or acceptor molecules in organic solar cells generally proceeds via (1) formation of charge transfer states and (2) their dissociation into charge separate...

Open AccessAssessing intra- and inter-molecular charge transfer excitations in non-fullerene acceptors using electroabsorption spectroscopy
Organic photovoltaic cells using Y6 non-fullerene acceptors have recently achieved high efficiency, and it was suggested to be attributed to the charge-transfer (CT) nature of the excitations in Y6 aggregates....

Copper-catalysed benzylic C–H coupling with alcohols via radical relay enabled by redox buffering
Cross-coupling reactions enable rapid, convergent synthesis of diverse molecules and provide the foundation for modern chemical synthesis. The most widely used methods employ sp2-hybridized coupling partners, suc...
