Effect of the dangling aromatic ring on neutral luminescent bis(phosphine) Cu(i)/Ag(i) complexes with the asymmetric pyridyl-tetrazolate ligands.

ABSTRACT: A series of neutral luminescent bis(phosphine) Cu(i) complexes of pyridyl-tetrazolate ligands (L¹-L³) with the general formula [Cu^I(L ⁿ )(P^P)] (1-6) were synthesized, which have been well characterized by IR, UV/vis, CV, ¹H NMR and ³¹P NMR. For comparison, an Ag(i) complex [Ag^I(L²)(PPh₃)₂] (7) was also synthesized. The crystal structures of 2 and 7 have been further determined by X-ray crystallography. All these Cu(i) compounds show bright luminescence in the solid state with photoluminescence quantum yields (PLQYs) in the range of 25.8% to 85.0%. More interestingly, the Cu(i) complexes bearing an additional dangling aromatic ring on the diimine ligands exhibit enhanced lum
