摘要近年来,一种新型具有聚集诱导发光特点的发光有机分子已经引起了广泛的关注。在这类发光材料中,四苯基乙烯(TPE)是一种具有简单分子结构但表现出极好的聚集诱导发光作用的发光分子,使用TPE作为基本的构建模块,嫁接羧酸等,延伸出多种高效率的固态发光有机配体。TPE基衍生物作为刚性有机配体来构建发光金属有机骨架,在催化、传感、检测等方面具有潜在的应用前景。我们主要研究了基于四苯乙烯构造的配体二羧酸基四苯乙烯(H2TPE),这个配体具有聚集诱导发光的特点。在不同条件下,H2TPE与Zn(II)、稀土金属等合成具有荧光的金属有机配合物。我们发现溶剂分子、反应物的浓度、反应温度及反应物的反应配比等合成条件都会影响配合物的质量。46821
Abstract: In recent years, a new kind that has gathered induced luminescence characteristics of light emitting organic molecules has caused wide attention. In this type of luminescent material, tetraphenylethylene (TPE) is a simple molecular structure but showed excellent gathered induce light-emitting molecule. Use TPE as the basic building blocks, and reactions such as carboxylic acids, extend the many efficient solid-state luminescent compounds. TPE derivatives as rigid organic ligand to build glowing metal organic skeleton, has a good application prospect catalysis,
chemical sensing and biological testing. In this thesis, We designed and synthesized a tetracarboxylate linker precursor (H2TPE).The ligand has the characteristics of the aggregation induced luminescence. Under different conditions, H2TPE and Zn (II) synthesis of the fluorescence metal-organic complexes. In the research of this paper, we found that the solvent molecules, anionic, synthetic conditions such as reaction temperature and the ratio of the reaction of the reactants will affect the quality of the complexes.
