Abstract
A hydrophillic bis(1,2,3-triazoly1)fluorene derivative was synthesized as a multi-photon absorbing zinc-ion sensing fluorescent probe. The fluorescent response was approximately five fold greater in presence of Zn(2+) resulting in a large binding constant (1 x 10(9)) for a 1/2 ligand to zinc complex. A four fold increase in the two-photon absorption cross section was achieved upon binding Zn(2+). In vitro two photon fluorescence microscopy imaging revealed a significant fluorescence increase upon introduction of Zn2(+) into HeLa cells and reversible Zn(2+) binding demonstrating the potential of this probe for zinc ion sensing.
