摘要：

Reactions in water between the sodium salt of 4-carboxyphenylboronic acid (Hcpb) and lanthanide ions (Pr-Nd, Sm Lu, and Y) led a family of lanthanide-based coordination polymers with general chemical formula {[Ln(cpbOH)-(H2O)(2)](cpb)}(infinity). Structural Characterizations were ensured by single-crystal X-ray diffraction and solid-state NMR spectroscopy -(B-11, C-13, and Y-89). This family of compounds constitutes the first example of lanthanide-based coordination polymers involving 4-carboxyphenylboronic acid as ligand. To evaluate their potential usefulness, luminescent and magnetic properties - of some of the compounds that constitute this family were,explored. From a magnetic point of view, the Yb(III) compound is the more promising. On the other hand; upon UV irradiation (lambda(exc) = 303 nm) ligand:phosphorescence is' quite intense and offers a sizable blue :Component to emission spectra. This is,quite unusual and can constitute an asset as far as white emission is targeted. Moreover; luminescence properties of these compounds are highly temperature-dependent, and some of them seem-promising as molecular thermometers.
