Заглавие : Meso-functionalization of calix[4]arene with 1,3,7-triazapyrene in the design of novel fluorophores with the dual target detection of Al3+ and Fe3+ cations Место публикации : RSC Advances. - 2021. - Vol. 11, № 11. - С. 6407-6414 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A meso-functionalization strategy has successfully been applied to the synthesis of novel 1,3,7-triazapyrene derivatives of calixarenes. The key synthetic step in these transformations providing the direct C–C bond formation is nucleophilic substitution of hydrogen (SNH) in 1,3,7-triazapyrene. General photophysical characteristics for these macrocyclic compounds, as well as features in emission properties upon addition of various metal cations have been elaborated. Studies using NMR spectroscopy have also shown a mutual effect of both calix[4]arene and 1,3,7-triazapyrene moieties on the coordination process. The complex stoichiometry and binding constants for Al3+ and Fe3+ guests have been explored with titration experiments. Доп.точки доступа: Moseev, T. D.; Lavrinchenko, I. A.; Varaksin, M.
