چکیده
Five new mononuclear lanthanide complexes are synthesized by adding the several nitrate hexahydrate salts, which for (Ln) Eu, Tb, Dy, Er, and Yb, with 9-anthracenecarboxylic acid (9-Hanthc) 2,2′:6,2″-terpyridine (TPY) in mixed solution of methanol dimethylformamide (DMF). The general formula is [Eu(9-anthc)3(TPY)(DMF)]·H2O (1Eu) where Eu(III) ennea-coordinated or [Ln(9-anthc)3(TPY)(H2O)]·H2O·DMF (Ln = Tb (2Tb), Dy (3Dy), Er (4Er), Yb (5Yb)) Ln(III) octa-coordinated. For compounds 3Dy, 4Er, 5Yb, dynamic ac magnetic study indicated field-induced single molecule magnet (SMM) behavior. photoluminescence studies solid state these show sensitization 4f-4f transitions 4Er 5Yb NIR region.

Two types of N,N'-bis(salicylidene)-1,3-propanediamine (H2L) lanthanide complexes, viz. [Ln(NO3)3(H2L)2]·0.2CH3OH [Ln = La (1), Ce (2) and Pr (3)] and [Ln(NO3)3(H2L)2]2·CH2Cl2·CH3OH [Ln = Nd (4), Sm (5), Eu (6), Gd (7), Tb (8) and Yb (9)], have been isolated by reactions of H2L with Ln(NO3)3·6H2O. X-ray crystallographic and PXRD analysis reveal that 1-3 are isomorphic possessing a novel one-dim...
