Multifunctional coordination compounds based on lanthanide ions and 5-bromonicotinic acid: magnetic, luminescence and anti-cancer properties†
Abstract
We report the formation of four novel multifunctional coordination compounds based on 5-bromonicotinic acid and different lanthanide(III) ions (Dy, Tb, Yb and Nd), synthesized by simple hydrothermal routes. These materials possess different structures and dimensionalities and show interesting magnetic and luminescence properties, as well as a complete absence of cytotoxicity both in cancer and non-cancer Caco-2 cells, transforming these new compounds into excellent candidates to be further investigated in the field of luminescence materials with biomedical applications.
