Abstract

The synthesis of a pendant donor emissive macrocyclic ligand Py2N4S2 with up to four naphthylmethylene arms (L) has been achieved. Their derivative solid metal complexes (Co2 +, Ni2 +, Cu2 +, Zn2 +, Cd2 +, Hg2 + and Ag+) have been isolated and characterized. The photophysical properties of the free...
