Abstract: Aza-boron-dipyrromethenes (Aza-BODIPYs) represent an important class of chromophores absorbing
and emitting in the near-infrared (NIR) region. They have unique optical and electronic features and
higher physiological and photo stability than other NIR dyes. Especially after the development of facile synthetic
routes, Aza-BODIPYs have become indispensable fluors that can find various applications ranging
from chemosensors, bioimaging, phototherapy, solar energy materials, photocatalysis, photon upconversion,
lasers, and optoelectronics. Herein, we review Aza-BODIPY based fluorescent and colorimetric chemosensors.
We show the potential and untapped toolbox of Aza-BODIPY based fluorescent and colorimetric
chemosensors. Hence, we divide the fluorescent and colorimetric chemosensors and probes into five sections
according to the target analytes. The first section begins with the chemosensors developed for pH. Next, we
discuss Aza-BODIPY based ion sensors, including metal ions and anions. Finally, we present the chemosensors
and probes concerning reactive oxygen (ROS) and nitrogen species (RNS) along with biologically relevant
species in the last two sections. We believe that Aza-BODIPYs are still in their infancy, and they have a
promising future for translation from the bench to real biomedical and materials science applications. After
two decades of intensive research, it seems that there are many more to come in this already fertile field.
Overall, we hope that future work will further expand the applications of Aza-BODIPY in many areas.
