Soji Shimizu, Aza-BODIPY synthesis towards vis/NIR functional chromophores based on a Schiff base forming reaction protocol using lactams and heteroaromatic amines, Chemical Communications, 10.1039/c9cc03365c, 2019.01, Aza-BODIPY is a class of heteroatom-containing BODIPY analogues targeting near infrared (NIR) chromophores and fluorophores. As a synthetic strategy towards aza-BODIPY structures, we have, recently, developed a Schiff base forming reaction using readily available lactams and heteroaromatic amines. Absorption and fluorescence of a series of compounds cover the whole range of the ultraviolet (UV)/visible (vis)/NIR regions. In addition, some compounds exhibit solid state emission, aggregation-induced emission enhancement, tunable fluorescence in the vis/NIR regions and non-linear optical properties. Furthermore, simple dimerization of aza-BODIPY chromophores caused unusual panchromatic absorption, whereas in combination with an N-confused porphyrin skeleton, multi-state NH tautomerism was achieved. In this Feature Article, wide applicability of this Schiff base forming reaction and optical and electrochemical properties of aza-BODIPY analogues thus synthesized are summarized including recent applications, such as bioimaging, photothermal cancer therapy and organic photovoltaics.. |
