Three nonfullerene acceptors (NFAs) with an acceptor− π–donor− π–acceptor (A− π–D− π–
A) structure, ie, IDT-3EsT, IDT-3EsT-2IC2F, and IDT-4EsT-2IC2F, were designed and …

In this article, a fluorinated heptacyclic dithienocyclopentacarbazole (DTC)-based non-
fullerene acceptor (NFA), DTC (4Ph)-4FIC, is synthesized and blended with J71, PBDB-T …

A new thieno [3, 2-b] thiophene-incorporated acceptor TTC has been developed. The TTC
acceptor was installed in a haptacyclic ladder-type core (BDCPDT) to furnish an n-type …

In recent years, non-fullerene acceptors, especially fused-ring electron acceptors (FREAs),
have been successfully applied to develop high-performance bulk-heterojunction organic …

Asymmetric acceptor–donor–acceptor (ADA)-type fused-ring electron acceptors (FREAs)
have recently attracted increasing interest due to their excellent photovoltaic properties …

Two novel small molecule acceptors (DTNIC6 and DTNIC8) based on a ladder-type
dithienonaphthalene (DTN) building block with linear (hexyl) or branched (2-ethylhexyl) …

Nonfused-ring electron acceptors have attracted much attention in recent years due to their
advantages of simple synthetic routes, high yields, low costs, reasonable power conversion …

Abstract 2D conjugated side‐chain engineering is an effective strategy that is widely utilized
to construct benzodithiophene‐based polymers. Herein, an unconjugated side‐chain …

Alkyl chain engineering is widely used to prepare high-performance donor materials.
However, relatively few studies have been focused on the alkyl chain optimization of …

Developing novel building blocks is essentially important to construct high-performance non-
fullerene electron acceptors (NFEAs). Benzotrithiophene (BTT) as an electron-donating …
