Design and Synthesis of Highly Stable N2O2-Type Azadipyrromethene NIR-II Dyes

Abstract N2O2-type azadipyrromethenes represent an important class of near-infrared (NIR) dyes that typically exhibit absorption below 900 nm. It is of great significance to extend their absorption beyond 900 nm. In this work, eight N2O2-type Zn (II)/Ni (II) azadipyrromethene NIR...

Dicyanodithioquinoline‐Based Donor Polymers With Large Dipole Moments for Efficient Organic Solar Cells Exceeding 20% Power Conversion Efficiency

ABSTRACT Constructing efficient donor polymers is a crucial strategy to break through the bottleneck of organic solar cells (OSCs). Herein, a new acceptor unit dicyanodithioquinoline (TQCN) with large dipole moment (12.90 Debye) was first used to construct high performance polyme...
