Abstract

The Ukrainian school of organic dye chemistry has long received worldwide recognition. Among the scientists whose achievements embody this success is Academician Oleksandr Oleksandrovych Ishchenko. Over more than half a century of fruitful research at the Department of Color and Structure of Organic Compounds of the Institute of Organic Chemistry of the National Academy of Sciences of Ukraine, he laid the foundations for the rational design of functional dyes for light-energy conversion, particularly for various laser technologies; became one of the pioneers of polymethine ion-pair photonics; developed methodological approaches to the study of electronic absorption and fluorescence spectra using the method of moments, which provided new insights into the electronic structure of organic chromophores; and made a significant contribution to the systematic study and interpretation of the solvatochromism of polymethines of different types. The driving force behind all these achievements was his enduring passion for science — a deep desire to learn and share knowledge with future generations of researchers.
