We firstly proposed the concept of “fused-ring electron acceptor(FREA)”,and designed and synthesized a series of FREAs.These FREAs present some advantages: 1)They have high electron mobilities similar to those of fullerenes; 2)They exhibit strong and broad absorption,especially in the 700–800 nm range,and can match with wide-bandgap donor polymers to achieve complementary absorption;
