摘要：

Self-assembly reactions of 2-(2'-hydroxypheny1-3'-methoxyl)naphthoimidazole (HL) and Ln(NO)(3).6H(2)O afford four mononuclear lanthanide complexes [Ln(HL)(2)(NO3)(3)] center dot CH2Cl2 (Ln=Sm (1), Eu (2), Tb (3)) and [Ln(HL)(2) (NO3)(2)(CH3OH)]NO3-CH3OH (Ln=Yb(4)). X-ray crystallographic analysis reveals that complexes 1 similar to 4 feature "butterfly-like" structure attributed to pi-pi interactions of the naphthalene rings of two ligands. Luminescent analysis reveals that only complex 4 exhibit essential NIR luminescence of Yb3+ ion with lifetime of 8.27 mu s in solid and 4.40 ps in CH3CN (c=1 x10' CCDC: 1441075, 1; 1441076, 2; 1441077, 3; 1441080, 4.
