Fluorescent Character of Cu(I/II) Complexes with Bisquinoline-based Ligands and Fluorometric Detection of Reductants

Abstract

The fluorescence ligands N, N′-bis(2-methylquinolyl)

Effect of methoxy substituents on fluorescent Zn2+/Cd2+ selectivity of bisquinoline derivatives with a N,N′-dimethylalkanediamine skeleton

“…The new bisquinoline ligands, TriMeOBQDMEN (3), 6-MeOBQDMPN ( 5) and TriMeOBQDMPN (6) (Chart 2), were prepared from N,N′-dimethylethylenediamine or N,N′dimethyl-1,3-propanediamine and corresponding 2-chloromethylquinolines (Schemes S1 and S2 †) in 41-46% yields after purification by column chromatography or recrystallization. BQDMEN (1), 38 6-MeOBQDMEN (2) 33 and BQDMPN (4) 39 were prepared as reported. The structure and purity of the compounds were confirmed by 1 H/ 13 C NMR (Fig.…”
