Nitro explosive and cation sensing by a luminescent 2D Cu(I) coordination polymer with multiple Lewis basic sites

A new 2D Cu(I)-based coordination polymer (CP) with Lewis basic sites-rich based on pytpy (pytpy = 4′-(4-pyridyl)-3,2′:6′,3″-terpyridine) ligand, [Cu(pytpy)(CN)](1), has been synthesized solvothermally. Luminescence properties of 1 were investigated, and the results show that 1 can work as highly sensitive sensors to nitro explosive and Fe3 +. The demonstrated that 1 could be a useful luminescent sensor for metal ions and organic small molecules.
