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

Abstract

In this paper, the novel uorescence probe XP based on Schiff-base was designed, synthesized and characterized, which could detect Y 3+ selectively and sensitively. The recognition mechanism of XP toward Y 3+ was studied by Job's plot and HRMS. It was investigated that stoichiometric ratio of the probe XP conjugated with Y 3+ was 1:2. And the detection limit was calculated as 0.30 µM. In addition, Y 3+ was recognized by the test paper made from XP. And the probe XP could selectivity toward Y 3+ in Caenorhabditis elegans and the main organs of mice. Thus, XP was considered to have some potential for application in bioimaging.
