The Novel Fluorescent Probe Toward Yttrium(III) and its Bioimaging.

In this paper, the novel fluorescence probe XP based on Schiff-base was designed, synthesized and characterized, which could detect Yselectively and sensitively. The recognition mechanism of XP toward Y was studied by Job's plot and HRMS. It was investigated that stoichiometric ratio of the probe XP conjugated with Y was 1:2. And the detection limit was calculated as 0.30 μM. In addition, Y was recognized by the test paper made from XP. And the probe XP could detect  Y selectively in Caenorhabditis elegans and the main organs of mice. Thus, XP was considered to have some potential for application in bioimaging.
