Two A-D-A′-D-A type nonfused-ring electron acceptors (NFREAs) Tz-H and Tz-Cl were designed and synthesized based on thiazole and 4-chlorothiazole, respectively. Compared with Tz-H, Tz-Cl possesses a concise synthetic route and highly planar backbone. Thus, Tz-Cl-based organic solar cell shows a considerable power conversion efficiency of 11.10%, demonstrating the great potential of S⋯N and S⋯Cl noncovalently conformational locks in achieving low-cost and high-performance NFREAs.
