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...
