… In 2015, our group pioneered a new class of electron acceptors, fused-ring electron acceptor
(FREA), as represented by the star molecule ITIC. The chemical features of FREAs include: …

… This contribution demonstrates the end-group engineering as a promising strategy for … In
this series of electron acceptors, end-group engineering could precisely regulate the electronic …

… Compared with high-performance FREAs, the NREAs-II type electron acceptors in this work
possessed simple backbones and only involved organotin-free compounds in the synthesis …

… design strategies can be classified into three parts such as core engineering, side-chain
engineering, and terminal group engineering. Notably, our review focuses on the effects of …

… this work still revolves around core engineering, side chain engineering and end group
engineering. The interaction of central cores and end groups can tune the intramolecular charge …

… This approach can maximize both short-circuit current density ( J SC ) and open-circuit voltage
(V OC ) at the same time, differing from the commonly used end group engineering that is …

… the concept of fused-ring electron acceptors (FREAs) and … π-electron-withdrawing end groups
linked by an electron-donating … The end groups of FREAs can increase electron affinity by …
