A highly selective fluorescent chemosensor for lead ions.
نویسندگان
چکیده
A simple fluorescent chemosensor 1 exhibits a 40-fold fluorescence enhancement upon addition of lead ion and yet is insensitive to most of univalent and divalent metal ions. The high affinity of 1 toward Pb2+ presumably results from the cooperative binding behaviors of two potential metal binding sites: the dicarbonyl and the 15-monoazacrown-5 ether.

A new fluorescent sensor based on the BODIPY fluorophore and the polyamide receptor for Pb(2+) was designed and synthesized. The sensor is highly selective for Pb(2+) over relevant competing metal ions, and sensitive to ppb levels of Pb(2+). It features the most sensitive probe to date for Pb(2+) ions in water.

A new pyrene derivative (1) containing a diaminomaleonitrile moiety exhibits high selectivity for Cu2þ detection. Significant fluorescence enhancement was observed with chemosensor 1 in the presence of Cu2þ. However, the metal ions Agþ, Ca2þ, Cd2þ, Co2þ, Fe2þ, Fe3þ, Hg2þ, Mg2þ, Mn2þ, Ni2þ, Pb2þ, and Zn2þ produced only minor changes in fluorescence values for the system. The apparent association...

Nowadays metal-organic frameworks with multiple luminescent centers are very fascinating as multifunctional luminescent material because of their luminescence properties, which could be systematically tuned by deliberate use of organic ligands and metal ions. In this research, we explored a microporous mixed-ligand MOF for highly selective and sensitive detection of metal ions. A two-fold inter...
