The article conveys some information:
A new tripodal chelate HL was synthesized from tridentate chelate bis(pyridin-2-ylmethyl)amine (BPA) and 8-hydroxyquinoline (8-HQ) to increase interaction between HL and Zn2+ and improve fluorescence sensitivity. Asym. and sym. dinuclear Zn(II) complex in rod and block shape were formed in CH3CN with identical formula, 1H NMR and fluorescence spectra in solution, but different IR, TG, and PXRD in solid. The fluorescence quantum yields are 0.0145 and 0.602 for HL and [ZnL]2+2 in ethanol resp. LOD reached 2.3 nM Zn2+, which is the highest sensitivity. The 7-position functionalization of 8-HQ is critical to the strong coordination and high fluorescence sensitivity. In the experiment, the researchers used many compounds, for example, Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Recommanded Product: Bis(pyridin-2-ylmethyl)amine)
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. The compound is a tridentate ligand in coordination chemistry and commonly used to produce Zn-based chemosensors/probes, such as Zinpry.Recommanded Product: Bis(pyridin-2-ylmethyl)amine
