The Synthesis And Characteristic Of Heterocyclic Aromatic Selenium(Sulfur) Compound

In this thesis the UV-vis and fluorenscence of Heterocyclic aromatic selenium(sulfur) compound were researched, and the cooperation of Heterocyclic aromatic selenium(sulfur) compound with different metal ions were synthesized. This thesis is divided into four chapters.In the first chapter, one briefly introduce of the research development of Heterocyclic aromatic selenium(sulfur) compound and the solid synthesis method.In the second chapter, the UV-vis of Heterocyclic aromatic selenium(sulfur) compound were researched and the affection of metal ions were discussed. As the increase of polarity of solvent, UV-vis of Heterocyclic aromatic selenium turn to red shift, and there is a exact matching concetration for the UV-vis effects from metal ions for MT. To TPT, the intensity of UV-vis was increased as the adding of metal ions except Zn(II), meanwhile there is a exact matching concetration from metal ions.In the third chapter, we discussed the fluorescence in different solvent of Heterocyclic aromatic selenium(sulfur) compound and the affection from different metal ions. The results indicated that Zn²⁺,Cu²⁺,Cr³⁺ could cause the luminescence reduction of spb, especially Cu²⁺,Cr³⁺, there are a luminescence quenching; in cse of spo, spdo, the adding of Zn²⁺ could cuse the fluorescence enhancement, but Cu²⁺,Cr³⁺ have the quenching effects to the luminescence.In the fourth chapter, we researched the synthesis and characteristic of Heterocyclic aromatic selenium(sulfur) compound cooperated with metal ions. According to the noramal temperature solid-state synthesis, the XRD of reagents were different from each other. With the purification and element analysis, we speculate the creation of metal ion conjuction with the 1:1proportion.
