A structurally orthogonal molecule (SBF-PDI4) with a 9,9′-spirobi[9H-fluorene] (SBF) core and four perylenediimide (PDI) at periphery was developed for use in polymer solar cells. Proper LUMO energy level (−4.1 eV) and good light absorption ability over 450–550 nm make it an excellent non-fullerene acceptor.
