Abstract Hemiindigo photoswitches, a class of chromophores derived from the well‐known indigo dye, have attracted considerable interest over past two decades. These compounds are unique in their ability to absorb light visible region spectrum both isomeric states, making them ideal for applications where high‐energy UV is not tolerated. A particularly attractive feature hemiindigoids that, despite rigid structures, they undergo significant and controllable changes during photoisomerisation process. Moreover, exhibit combination high thermal bistability, pronounced photochromism, fast, efficient photoisomerisation, positioning hemiindigoid photoswitches as versatile chromophores. This review summarises current developments advances including synthesis, photoswitching performance, applications, with strong focus on practical use reversible triggers fields ranging photopharmacology advanced materials.
