A 99 Azapyrene-based fluorophores: synthesis and photophysical properties / O. S. Taniya, A. F. Khasanov, M. V. Varaksin [et al.] // New Journal of Chemistry. - 2021. - Vol. 45, № 45. - P20955-20971 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Azapyrenes are the nitrogen isosteres of pyrene. Based on theoretical and experimental studies, electron–acceptor azapyrene domains may be considered as convenient scaffolds for constructing a large variety of “push–pull” π-conjugated chromophores with pronounced ICT properties. Over the past decade, due to the unrelenting interest in functional materials and modern methodologies such as cross-coupling, peri-annulation, direct C–H-functionalization, etc., methods for the synthesis of aryl(alkyl) K-functionalized azapyrenes and other derivatives have been developed, and their photophysical and electrochemical properties have been studied. This short review aims at critical analysis of the best known/modern methods for the preparation of functionalized azapyrene derivatives, as well as an assessment of their photophysical/electrochemical properties in comparison with the structural and electronic properties of the parent pyrene. |
