A Selective and Ratiometric Bifunctional Fluorescent Probe for Al3+ Ion and Proton
摘要:
A new bifunctional probe based on a pyrene amino acid conjugate for the differential response of Al3+ and H+ was demonstrated for the first time. Interestingly, two solvent-dependent sensing mechanisms for Al3+, which feature a ratiometric change from excimer to monomer in CH3OH and a turn-on response in water, are also disclosed.
