Functionalized benzazines as luminescent materials and components for optoelectronics

Extensive research on the synthesis and application of benzazine derivatives for electronic devices, luminescent elements, photoelectric conversion elements, and image sensors has been published recently. This review covers article data obtained within the period 2012 - 2018 on the synthesis and optical properties of functionalized quinolines, quinoxalines and quinazolines. Arylvinyl, arylethynyl and (het)aryl derivatives of these benzazines, their photoluminescence and photoisomerization are discussed. Examples of photosensitive annelated, oligo- and polymeric benzazines and also coordination compounds with benzazine ligands are reviewed.
