摘要：荧光材料在检测领域发挥着至关重要的作用，但是传统荧光材料在聚集态时总是不可避免的会发生荧光强度下降的现象，这一缺点大大的限制了传统荧光材料的应用。因此，2001年聚集诱导发光材料的出现引起了学术界的广泛关注，并在十几年间获得了极大的发展。含有TPE单元的聚集诱导发光材料作为一种新型的发光材料，具有很多独特而且优异的性质，在生物/化学检测领域获得极为广泛的应用。本文重点研究了不同因素对乳液荧光强度的影响。

以KH560为偶联剂，加入TPE与KH560亲有机的基团反应，加入硅溶胶与KH560亲无机的基团反应，以此来固定住TPE。将产物与丙烯酸进行乳液聚合反应，制得核壳结构的乳液。本文还通过控制甲基丙烯酸甲酯（MMA），丙烯酸异辛酯（2-EHA）和丙烯酸羟乙酯（HEA）用量来改变涂料玻璃化温度（Tg）。实验通过控制变量法，重点研究了不同玻璃化温度、不同浓度、不同蒸气对乳液荧光强度的影响。测试了不同玻璃化温度乳液的基本性能、荧光强度，并进行了红外光谱分析、粒径分析、热重分析、透射电镜分析、XRD分析等对乳液性能进行综合评定。

综合实验数据，我们可以得出结论：气相二氧化硅能较好的固定住TPE荧光分子。玻璃化温度的变化对荧光强度的影响不大，乳液的荧光强度随TPE含量的增加呈上升趋势，凝胶率也随TPE浓度的增加而升高。在玻璃化温度为20℃时，乳胶粒子直径最小，分子量分布也最均匀，可制得综合性能良好的乳液。

abstract：Fluorescent materials play a vital role in testing,but it is inevitable that the fluorescence intensity decreases when the traditional fluorescent material is gathered,this drawback greatly limits the application of traditional fluorescent materials.As a result, the emergence of light-emitting materials in 2001 has drawn wide attention in academia,and in the last ten years, it has been very developed.The aggregation induced luminescent material containing TPE units is a new type of luminescent material,it has many unique and excellent properties,it has been widely used in the field of biological/chemical testing.This paper focuses on the effect of different factors on the strength of emulsion fluorescence.

With the KH560 as an coupling agent, add TPE to the organic group of the KH560,add silicon sol and KH560 pro inorganic group reactions in order to stick to TPE.Emulsion polymerization of the product with acrylic and the emulsion of the shell structure.This paper also changes the coating temperature (Tg) by controlling methyl methacrylate (MMA), acrylate (2-EHA) and acrylate (HEA).The influence of different glass temperature, different concentration and different steam on the strength of emulsion fluorescence was studied by controlling variable method.The basic properties and fluorescence intensity of different glass temperature emulsion were tested,the properties of the emulsion were evaluated by infrared spectroscopy, particle size analysis, thermal analysis, transmission electron microscope analysis, XRD analysis, etc.

Combining experimental data, we can conclude that the gas phase silicon dioxide can hold the TPE fluorescent molecules better.Changes in glass temperature have little effect on the intensity of fluorescence,the fluorescence intensity of the emulsion increases with the increase of TPE content,and the gel rate also increases with TPE concentration.In the glass transition temperature is 20 ℃, the latex particle diameter of the smallest, molecular weight distribution and uniform, good comprehensive performance can be obtained from the emulsion.
