摘要

In this work, a simple building block (POBT) based on bithiophene was designed and synthesized, which could be regarded as tailoring from the fused-ring CPT unit. Two novel NFREAs based on CPT and POBT were developed, and PBDB-T:TT-POBT based PSC devices showed a much better PCE than the TT-CPT counterpart.

Abstract

Nonfused ring electron acceptors (NFREAs) have attracted much attention due to their concise synthetic routes and low cost. However, developing high-performance NFREAs with simple structure remains a great challenge. In this work, a simple building block (POBT) with noncovalently conformational locks (NoCLs) was designed and synthesized. Single-crystal X-ray study indicated the presence of S···O NOCLs in POBT, thus enabling it to possess a coplanar conformation comparable to that of fused-ring CPT. Two novel NFREAs based on CPT and POBT were developed, namely ,TT-CPT, and ,TT-POBT, respectively. Besides,TT-POBT, possessed a smaller Stokes shift and a reduced reorganization energy compared with ,TT-CPT, indicating the introduction of S···O NoCLs can enhance the molecular rigidity even if simplifying the molecular structure. As a result, the ,TT-POBT,-based PSC device afforded an impressive power conversion efficiency of 11.15%, much higher than that of ,TT-CPT, counterpart (7.03%), mainly resulting from the tighter ,π,-,π, stacking, improved and balanced charge transport, and more favorable film morphology. This work demonstrates the potential of the simple building block POBT with NoCLs towards constructing low-cost and high-performance NFREAs.
