ABSTRACT

With the reaction between 1,3,5-tris(2-methylimidazol-1-yl)benzene (timb), a designed tripodal connector and Zn(NO₃)₂ · 6H₂O in the presence of a hydroxyl functionalised carboxylate ligand isophthalic acid (OH-H₂IPA), a novel luminescent coordination polymer (CP) containing Zn(II) ions as nodes was created through applying the reaction of solvothermal method, and its chemical formula is {[Zn₅(timb)₄(OH–IPA)₄]·2NO₃ · 2DMA·2H₂O}_n (1). Because of complex 1 excellent photoluminescence performances and water stability, it reveals the phenomenon of luminescence turn-off for the Fe³⁺ cation, and the value of K_sv is 9.59 × 10³ M⁻¹ (R² = 0.9913). The application values of the new compound and its ligands on the psoriasis metabolic syndrome were finally evaluated.

摘要

1,3,5-tris(2-methylimidazol-1-yl)benzo (timb), 一种设计的三脚连接器和 Zn(NO ₃ ) ₂  · 6H ₂ O 在羟基官能化的羧酸酯配体间苯二甲酸的存在下反应酸(OH-H ₂ IPA)，采用溶剂热法反应制备了一种以Zn(II)离子为节点的新型发光配位聚合物(CP)，其化学式为{[Zn ₅ (timb) ₄ (OH –IPA) ₄ ]·2NO ₃  · 2DMA·2H ₂ O} _n ( 1 )。由于复杂1优异的光致发光性能和水稳定性，揭示了Fe ³⁺阳离子的发光关闭现象，K _sv值为9.59 × 10 ³ M ^-1 (R ²  = 0.9913)。最后评价了新化合物及其配体在银屑病代谢综合征中的应用价值。
