Abstract

Two new ternary complexes of 1-(2-thienyl)-3-(p-phenylethynylphenyl)-1,3-propanedione (HTPP) and 1,10-phenanthroline (phen) with Sm3+ and Dy3+ were synthesized. The composition of the ternary complexes was characterized as Sm(TPP)3phen and Dy(TPP)3phen, respectively, by infrared (IR) spectra, chemical analysis, elemental analysis, and thermodynamic analysis. At room temperature, under UV light excitation, the Sm3+ and Dy3+ complexes exhibit characteristic emissions of the central ions. It is found that the fluorescence intensity of Sm(TPP)3phen is stronger than that of Dy(TPP)3phen. In order to explain this phenomenon, an accurate quantum chemistry calculation was carried out, and the result is in good agreement with the experiment data.
