A reversible interconversion of diarylethenes between two isomers became a powerful means for the development of new materials with a photoswitching function. The versatility of this phenomenon allows a wide variety of heterocyclic systems with advanced properties to be applied. In this mini-review, we analyzed the effect of incorporation of silole and phosphole heterocycles into the diarylethene framework, in particular, its effect on absorbance, quantum yields and thermal stability. The elusive aromaticity and high photostability of silole and phosphole derivatives allowed new highly efficient photoswitches to be obtained. Moreover, the phosphorous atom of the latter displayed a unique ability to undergo chemical modifications that was used for fine-tuning of molecules and development of functional photoswitches. These results clearly demonstrated that incorporation of more exotic moieties into diarylethene remains a promising way to advanced molecules and materials. (C) 2021 Elsevier B.V.
