A heavy metals sensor (2-N,N-bis(pyridin-2-ylmethyl)methanamine-BODIPY, ) for the recognition of Pb2+, Ba2+, Cr2+, Cd2+, Hg2+, Sn2+, and Zn2+ was developed by anchoring (bis(pyridin-2-ylmethyl)amine) DPA unit to the BODIPY framework. It exhibited excellent sensitivity and selectivity against other competent metal ions. The stoichiometry of and metal ions were determined to be 1:1. The limit of detection of toward Pb2+, Ba2+, Cr2+, Cd2+, Hg2+, Sn2+, and Zn2+ was ranged from 60.07 to 89.37 nM. Photo induced transfer (PET) leads to the weak emission of BODIPY unit. When metal ions anchored with DPA, PET was blocked due to the weak electron donating ability of N in DPA to BODIPY and the highly emissive character of BODIPY was recovered, establishing a fluorescence switch. After reading the article, we found that the author used Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0SDS of cas: 1539-42-0)
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. As a tridentate ligand this compound provides three nitrogen donors that affords good selectivity for Zn2+ over biologically relevant metals such as Na+, K+, Mg2+ and Ca2+, and leaves coordination sites free for anion binding.
