Near-infrared emissive mononuclear lanthanide(III) complexes based on chiral Schiff base ligands: synthesis, crystal structure, luminescent, and magnetic properties

In this study, novel chiral mononuclear complexes (teaH)[Ln((R,R)-dnsalcd)2] (Ln = Nd3+ (1), Ho3+ (2), Er3+ (3), Yb3+ (4), and Gd3+ (5), where teaH = triethylammonium and (R,R)-H2dnsalcd = (R,R)-N,N'-bis(3,5-dinitrosalicylidene)-1,2-cyclohexanediamine, were...
