Nonfullerene-based organic solar cells (OSCs) have made a huge breakthrough in the
recent years. Introducing a proper side chain on the π-conjugated backbone plays a vital …

A new acceptor–donor–acceptor‐structured nonfullerene acceptor ITCC (3, 9‐bis (4‐(1, 1‐
dicyanomethylene)‐3‐methylene‐2‐oxo‐cyclopenta [b] thiophen)‐5, 5, 11, 11‐tetrakis (4 …

In recent years, non-fused non-fullerene acceptors (NFAs) have attracted increasing
consideration due to several advantages, which include simple preparation, superior yield …

In this study, we designed, synthesized, and characterized an A–D–A′–D–A-type
indacenodithienothiophene (IDTT)-based molecular acceptor that exhibited a broader …

A sidechain optimization strategy is widely utilized in organic semiconductor materials to
optimize both solubility and solid-state properties. Here, we introduced octyl rather than …

A fused heptacyclic electron acceptor, ITIC5, based on a benzodi (cyclopentadithiophene)
core flanked by thiophene-fused termini, is designed, synthesized, and compared with its …

In this work, three dithieno [3, 2-b: 2′, 3′-d] pyrrol fused-ring electron acceptors (IPT-2F,
IPTT-2F, and IPTTT-2F) have been successfully developed as efficient asymmetric …

Three small molecules IDIC8-M, IDIC8-H, and IDIC8-F with alkylated indacenodithiophene
unit as the central building block and 2-(3-oxo-2, 3-dihydroinden-1-ylidene) malononitrile …

An NC-FIC nonfullerene acceptor, using a didodecylnaphthodithiophene (NDT) embedded
octacyclic ladder-type donor NC, had been described previously. In this work, a new cross …

Fused-ring electron acceptors (FREAs) have attracted immense interest owing to their ability
for facile structural modification and good thermal and optical characteristics. Among these …
