Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 499-40-1, C12H22O11. A document type is Article, introducing its new discovery.
A new fluorescent chemosensor 5-(p-N,N?-bis(2-pyridyl)amino)phenyl-10,15,20-tris(p-methoxyphenyl)porphyrin zinc has been designed and synthesized by the Ullmann-type coupling. It displays high selectivity for Cu2+ ion and exhibits fluorescence quenching upon binding of Cu2+ ion with an “on-off” type fluoroionophoric switching property, and its fluorescence can be revived by addition of EDTA disodium solution.
