Abstract

Cu(II)-Ln(III) complexes of H-2(fsal-n,m) ((n,m = (2,3), (3,2) (3,3); Ln =Lanthanide), fsal-n,m-Cu,Ln, have been synthesized by a template reaction,where fsal-n,m(2-) denotes dinucleating macrocycles with two 2,6-bis(iminomethyl)-4-methylphenolate entities combined through two lateral chains, -(CH2)(n)- and -(CH2)(m)-, at the imino nitrogens. Temperature dependences of magnetic susceptibilities for the Cu(II)-Gd(III) complexes showed that an intramolecular ferromagnetic interaction operates between Cu(II) and Gd(III)ions in fsal-2,3-Cu,Gd and fsal-3,2-Cu,Gd. Absorption spectra suggested that substrates possessing N- and O-donor groups such as amino alcohols are specifically bound at the Cu-Ln centre of fsal-2,3-Cu,Ln, through the nitrogen to the copper site and through the oxygen to the lanthanide site. The fluorescence intensity of Eu(III) decreased drastically on forming the Cu-Eu complex.
