Synthesis and Optical Absorption Properties of Yttrium (III) Acylaminocarboxylates Complexes

Abstract

Yttrium (III) complexes of Acylaminocarboxylates (N-octanoyl-alaninates, N-octanoyl-phenylalaninate, N-octanoyl-serinates) were prepared by chemical reaction method in methanol solution. The abbreviation of these yttrium (III) complexes were Y(oct-ala)3, Y(oct-phe)3 and Y(oct-ser)3 respectively. These complexes were characterized by elemental analysis, XRD, FT-IR, 1H NMR, UV-Vis and UV-Vis diffuse reflection. WAXD and SAXS profiles show the amorphous structure of the yttrium complexes. FT-IR and 1H NMR spectrum establish the molecular formula, functional group information and coordination structure of the yttrium complexes. The optical absorption properties were investigated by UV-Vis and UV-Vis diffuse reflection spectrum.
