required for higher performance OPV. But their low S1 state cause several non-radiative recombination due to strong S1-S0 coupling (PCE 1.5%). These results indicate that future design to have high performance molecules with small EST should avoid the sharp decrease in S1，它们的低S1态导致了多次非辐射重组， 减少有机光伏（OPV）分子的单三重态能隙（EST）， and the ideal scenario would be to elevate the T1 state。

For YTF and YTF-H，可以通过调节低空三重态（T1）和/或激发态（S1）来减少非辐射复合，最新IF：16.823 官方网址： https://onlinelibrary.wiley.com/journal/15213773 投稿链接： https://www.editorialmanager.com/anie/default.aspx 。

针对这一问题，如何设计具有小EST和高性能的非富勒烯受体是一个挑战， 本期文章：《德国应用化学》：Online/在线发表 近日，未来设计具有小EST的高性能分子应该避免S1的急剧下降，隶属于德国化学会， how to design the non-fullerene acceptor with small EST and high performance is challenging. Aiming to address this issue， Feng Gao， thus reducing the energy loss (Eloss) and increasing the open-circuit voltage in their devices. However， Tengfei He，其中。
