| Abstract: | In ethanol solution,oil-soluble tea polyphenols and Se4+ in molar ratio 4∶1 reacted at pH=3.0 and 40～45 ℃ for 20 min to afford the title complexes through phase transfer method.The product yield is 52.33%.They were characterized by UV absorption spectra(651.5,422.0,273.0,262.0) nm,FTIR(ν=3 422.19,2 920.62,2 851.05,1 705.42,1 615.42,1 514.42,1 466.16,1 376.90,1 228.85,1 047.74,716.84 cm-1),1HNMR(δ=0.781,1.191～1.587,2.151～2.165,2.476,3.122,3.970～3.984,4.978～5.953,6.531～7.331) and XRD analysis(λ/nm=3.689 3,4.111 9,7.135 2,11.859 7,15.619 1).The stereo configuration is a center selenium ion with four or five ligands. |
