N-annulated perylene diimide (PDI)-based nonfulerene acceptors have gained sustained attention because of their high absorption coefficient, elevated ELUMO energy level derived from electron-donating property the formed pyrrolic ring and excellent solution processing capability. Two PDI dimers, termed as, TVT-(PPDI-B)2 TYT-(PPDI-B)2, selecting (E)-1,2-di(thien-2-yl)ethylene (TVT) 1,2-di(thien-2-yl)acetylene (TYT) as middle linkers, N-butyl-[1,12-b,c,d]pyrrole-N,Nʹ-bis(2-hexyldecyl)perylene (PPDI-B) fused aromatic moiety two wings, were developed to investigate influence linking core on absorption, electrochemical property, molecular geometry stacking interaction, charge mobility, morphology photovoltaic property. It was exhibited that improved 0.05 eV up-shifted ELUMO, drastically reduced twisting angle 68.00o 27.92o between moieties enhanced aggregation found after substituting TVT with TYT. Accordingly, under best condition, TVT-(PPDI-B)2-based device VOC 0.94, JSC 3.70 mA‧cm−2, FF 30.69% consequently PCE 1.07% when blending PTB7-Th. In contrast, TYT-(PPDI-B)2-based afforded 4.26% increased 0.98 V, 86.49% 6.90 mA‧cm−2 55.16% raised 47.62%, collectively contributed a 202% 3.23%. This efficiency enhancement mainly attributed more efficient exciton dissociation electron weakened recombination, suitable morphology. Interestingly, 0.14⁓0.20 V achieved applying N-annulation strategy at bay-position building block. indicates precisely tuning connecting unit in PDI-based dimers can fruitfully affect optoelectronic morphology, thus further boost corresponding efficiency.
