A heavy metals sensor (2-N,N-bis(pyridin-2-ylmethyl)methanamine-BODIPY,DB) for the recognition of Pb2+, Ba2+, Cr2+, Cd2+, Hg2+, Sn2+, and Zn(2+)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 ofDBand metal ions were determined to be 1:1. The limit of detection ofDBtoward Pb2+, Ba2+, Cr2+, Cd2+, Hg2+, Sn2+, and Zn(2+)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 ofNin DPA to BODIPY and the highly emissive character of BODIPY was recovered, establishing a fluorescence switch.
