[Synthesis and optical properties of Nd(III) perfluoro-carboxylate complexes with 2,2'-bipyridine].

A series of neodymium complexes, Nd(CF3COO)3 x Dipy, Nd(C2F5 COO)3 x Dipy and Nd(C3F7COO)3 x Dipy were synthesized and characterized by FTIR spectra, elemental analysis, thermogravimetric analysis, UV-Vis-NIR absorption spectra and PL spectra. The decomposition temperature was found to be more than 260 C and maximum weight losses rates above 340 degrees C which indicate that they have good thermal stability. The low vibrational energy C-F bonds were used to replace the C-H bonds in organic group for improving the optical properties of materials.
