Actual aspects of the chemistry of dipyrrin dyes and prospects for their application in molecular sensorics

The results of research on the correlation between molecular structure and spectral luminescent and photophysical properties for a new class of dyes and luminophores based on dipyrrins, bis(dipyrrins), and their coordination compounds in different media are summarized. The new perspective applications of dipyrrin dyes and luminophores as fluorescent sensors for measuring the polarity, viscosity, and temperature of the medium and highly sensitive and selective fluorescent “off-on” chemosensors for detecting Zn 2+ , Cd 2+ , and Hg 2+ cations in weakly polar and nonpolar organic solvents and biological systems are discussed.
