Abstract

Quinolyl-1,2,3-triazole ligand supported [Cu₄I₄] stair-step aggregates [Cu₄I₄(L1)₂] (1), [Cu₄I₄(L2)₂] (2), [Cu₄I₄(L3)₂] (3), [Cu₄I₄(L4)₂] (4), [Cu₄I₄(L5)₂] (5), and six-membered [Cu₃I₃] metallacycle based coordination polymers [Cu₂I₂(L6)]_n (6) and [Cu₂I₂(L7)]_n (7) (ligands are 2-((1H-1,2,3-triazol-1-yl)methyl)quinoline (L1), 2-((4-alkyl-1H-1,2,3-triazol-1-yl)methyl)quinoline (propyl, butyl and isobutyl for L2, L3 and L4, respectively) and 2-(1-((quinolin-2-yl)methyl)-1H-1,2,3-triazol-4-yl)alcohol (methanol, ethanol and propanol for L5, L6 and L7, respectively)) have been prepared and characterized by single-crystal X-ray diffraction (XRD), powder XRD, photoluminescence spectroscopy and thermogravimetric analysis. Complexes 1-5 are stair-step [Cu₄I₄] aggregate structures supported by two quinolyl-triazole hybrid ligands. Complexes 6 and 7 are rare cyclic [Cu₃I₃] aggregate-based 1-D coordination polymers. All ligands adopt a common tridentate-bridging coordination mode. These complexes are strongly luminescent with a yellow emission (500-700 nm) in the solid state. This journal is
