摘要

A metal ion sensing fluorophore L that exhibits a large two-photon absorption cross-section has been synthesized in good yields. The influences of different metal ion inputs, on the one- and two-photon spectroscopic properties of L, have been investigated. The ligand itself does not show any fluorescence although in presence of a metal ion like Zn (II), Cd (II), Mg (II) or Ca (II), a∼ 25 time enhancement of fluorescence is observed. The ligand with symmetrical ...
