A symmetric and selective fluorescent Cu (II) sensor based on bodipy and s-triazine

A symmetric fluorescent sensor based on Bodipy for Cu (II) ion was designed according to binding site-signaling subunit approach. This sensor was prepared by reaction of 2,4-diamino-6-methyl-1,3,5-triazine with a 8-{4-(chloromethyl)phenyl}-2,6-diethyl-4,4-difluoro-1,3,5,7-tetramethyl -4-bora-3a,4a-diaza-s-indacene in dimethyl formamide. The synthesis and the photophysical properties of Bodipy-triazine derivative were investigated in presence of some metal ion. The results show that this symmetrical fluorescent sensor has a high selectivity for Cu (II) ion. - Highlight: • A symmetric fluorescenct Cu (II) sensor based on Bodipy and s-triazine was designed according to binding site-signaling subunit approach. • The spectroscopic properties of the fluorescent sensor were investigated. • The symmetrical s-Bodipy-triazine has a high selectivity for Cu (II) metal ion
