Side-chain engineering has been considered as one of the most promising strategies to
optimize non-fullerene acceptors. In this work, we use side-chain engineering to synthesize …

To develop the low‐cost nonfullerene acceptors (NFAs), two fully non‐fused NFAs (TBT‐2
and TBT‐6) with ortho‐bis ((2‐ethylhexyl) oxy) benzene unit and different side chains onto …

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 …

Producing high-performance and inexpensive non-fullerene acceptors is a great challenge
in the field of organic photovoltaics. Herein, three non-fused ring electron acceptors …

In this work, we have developed two A 1-A 2-DA 2-A 1 type small molecule electron
acceptors (DTFBT-1, DTFBT-2) with twin spiro-type core structure as D unit …

Main observation and conclusion Recently, the asymmetric nonfullerene acceptors (NFAs)
with acceptor‐donor‐acceptor (A‐D‐A) structure have been developed rapidly, especially …

Comprehensive design ideas on the fused-ring donor-core in state-of-the-art acceptor-donor-
acceptor (ADA) nonfullerene acceptors (NFAs) are still of great importance for regulating the …

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 …

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

Different from the commonly studied non-fullerene electron acceptors with large fused
backbone architecture and tedious synthesis steps, non-fused ring electron acceptors are …
