In this review, the data on the application of isoindigo derivatives in the chemistry of functional materials are analyzed and summarized. These bisheterocycles can be used in the creation of organic solar cells, sensors, lithium ion batteries as well as in OFET and OLED technologies. The potentials of the use of polymer structures based on isoindigo as photoactive component in the photoelectrochemical reduction of water, as matrix for MALDI spectrometry and in photothermal cancer therapy are also shown. Data published over the past 5 years, including works published at the beginning of 2021, are given.

Condensation reactions of isatin derivatives with 3,5-di( tert-butyl)-4-hydroxybenzyl acetate and the Girard’s reagent T has afforded a series of novel water-soluble isatin-3-acyl hydrazones...

Isatin derivatives are widely used in organic synthesis, in medicinal chemistry and in the chemistry of materials. This report summarizes modern trends in the synthesis of substituted indolin-2,3-diones covering the literature from 2007 to 2017. Studies on the influence of the structure of substituents in the initial substrates on the formation of the heterocyclic isatin system and the yields of the target compounds are also discussed.1 Introduction2 Oxidation of Indole Derivatives3 Cyclization of o-Aminoacetophenones4 Cyclization of N-Acylanilines5 Miscellaneous6 Conclusion
