Abstract
Herein, we report the facile synthesis and properties of a chiral perylene diimide (PDI)-embedded conjugated macrocycle (cyclo[6]paraphenylene-1,7-perylene diimide, [6]CPP-PDI1,7) by Pd-catalyzed Suzuki coupling and a subsequent reductive aromatization reaction in two steps. The PDI-embedded conjugated macrocycle showed a significant redshift (>110 nm for absorption) compared to the PDI molecule. Moreover, efficient resolution of chiral enantiomers with (P)/(M)-[6]CPP-PDI1,7 was achieved by high-performance liquid chromatography, and their chiral properties were investigated by circular dichroism spectroscopy. The realization of [6]CPP-PDI1,7 expands the scope of the precise synthesis of PDI-embedded chiral conjugated macrocycles and explores its unique physical properties.

Abstract
An electron acceptor with a truxene core and ring-fusion perylene diimide (PDI) tripolymer annulated by selenium (Se) branch, named as FTr-3PDI-Se, is designed and synthesized. FTr-3PDI-Se exhibits large conjugated planar conformation, strong absorption spectra in the regions of 300-400 and 450-550 nm, the deep HOMO energy level of 6.10 eV, and high decomposition temperature above 400°C. The FTr-3PDI-Se: PBDB-T-2Cl based device achieved a disappointing power conversion efficiency (PCE) of 1.6% together with a high V oc of 1.12 V. The low PCE was due to the large aggregates of blend film, the imbalanced hole/electron transport and low PL quenching efficiencies. The high V oc can be attributed to the high-lying LUMO level of FTr-3PDI-Se and the low-lying HOMO level of PBDB-T-2Cl. Our research presents an interesting and effective molecule-designing method to develop non-fullerene acceptor.
