Environmentally friendly acylaminocarboxylates yttrium (III) complexes: Synthesis, solubility and aggregation behavior

Abstract

In order to investigate the effect of differences in amino acid alkyl chains, In order to investigate the effect of difference amino acid alkyl chains on the Rare earth complexes, the lipoaminic acids rare earth surfactant complexes of yttrium hexanoyl alaninc acid (Y(hex-ala)3), yttrium octanoyl alaninc (Y(oct-ala)3) and yttrium dodecanoyl alaninc acid (Y(dod-ala)3) are synthesized by the reaction of C9H17NO3, C11H21NO3, C15H29NO3 with YCl3, respectively. These complexes have been compared to the yttrium octanoate soap (Y(octnt)3). At the same time, the formation of molecular glasses of these complexes are compared with the aggregation behavior in solution, evaluate properties as glass. Furthermore, the aggregation behavior of the above surfactant complexes in the pure solvent are studied using nuclear magnetic resonance (NMR) spectrometry, vapor pressure osmometry (VPO), electrical conductivity and Fourier Transform-Infrared spectroscopy (FT-IR). As results, these Y(III) complexes aggregate in the organic solvents system and tend to form aggregates. After the organic solvents evaporated, organic rare earth vitreous bodies was obtained.
