Abstract

Abstract: Three rare earth complexes of [Ln(5-Cl-2MOBA)₃phen]₂ (Ln=Nd(1), Eu(2), Ho(3); 5-Cl- 2MOBA: 5-chloro-2-methoxybenzoate; phen: 1,10-phenanthroline) were synthesized and characterized by elemental analysis, thermogravimetry-differential thermogravimetry-differential scanning calorimetry (TG-DTG-DSC), infrared (IR) spectra, ultraviolet (UV) spectra, and molar conductance techniques. The fluorescence spectra showed that complex (2) emitted a characteristic fluorescence of the Eu³⁺ ions. The thermal properties are discussed by thermogravimetry - differential scanning calorimetry / Fourier transform infrared (TG-DSC/FTIR) techniques. And the three-dimensional IR accumulation spectra for the three complexes were also analyzed.

Key words: Rare earth complex, Thermal decomposition mechanism, Three-dimensional infrared accumulation spectrum, Evolved gas, Thermogravimetry-differential scanning calorimetry
