In this contribution, based on combination of the direct and indirect linkage manners of PDI units at the bay position, a propeller\u2010shaped PDI hexamer <jats:bold>T\u2010DPDI<\/jats:bold> was designed and synthesized. The singly bonded PDI dimer <jats:bold>DPDI<\/jats:bold> and the benzene ring cored PDI trimer <jats:bold>TPDI<\/jats:bold> were synthesized for comparison. The photovoltaic performances of these three PDI derivatives were investigated using the commercially available PTB7\u2010Th as electron donor. A best power conversion efficiency (PCE) of 6.58% was obtained for <jats:bold>T\u2010DPDI<\/jats:bold> based organic solar cells (OSCs), which is higher than those of <jats:bold>DPDI<\/jats:bold> and <jats:bold>TPDI<\/jats:bold> based ones. The superior photovoltaic performance of <jats:bold>T\u2010DPDI<\/jats:bold> can be ascribed to its stronger absorption and more favorable morphology. This study presents an interesting example of improving the photovoltaic performances of PDI based NFAs by hybridizing the direct and indirect linkage manners.<\/jats:p>","DOI":"10.1002\/asia.202101018","type":"journal-article","created":{"date-parts":[[2021,9,28]],"date-time":"2021-09-28T02:29:09Z","timestamp":1632796149000},"page":"3767-3773","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Perylene Diimide Hexamer Based on Combination of Direct and Indirect Linkage Manners for Non\u2010fullerene Organic Solar Cells"],"prefix":"10.1002","volume":"16","author":[{"given":"Cetao","family":"Hu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Center of Smart Materials and Devices Wuhan University of Technology  No. 122 Luoshi Road Wuhan 430070 P.
