中文摘要： 挥发性有机物分子（VOCs)的检测对于生态环境和人类健康有着重要意义，因此研制对VOCs传感的功能材料具有重要的理论意义和实用价值。针对荧光传感的响应时间和灵敏度等特点，将具有共轭π电子体系的芘基配体引入骨架，进而制备、筛选具有强发光效率和荧光放大效应的化合物，是一种有效提高VOCs荧光传感性能的策略。本项目以芘基为母体，设计并合成系列多孔荧光化合物。通过对所合成的化合物进行客体交换、VOCs荧光传感性能的研究及理论模拟主体框架与客体VOCs分子之间的相互作用，研究此类材料的结构-效能关系，为筛选具有高灵敏度和快速响应能力的荧光传感器的研究奠定实验和理论基础。本项目的实施，为设计和开发新型MOFs荧光传感器提供了新的研究思路，拓宽了金属有机框架化合物作为荧光传感材料的应用范围。

英文摘要： The detection of volatile organic compounds (VOCs) is a significant research which is important for the field of ecological environment and human health, so the development of functional materials with VOCs sensing properties has important theoretical significance and practical value. According to the characteristics of fluorescence response time and the sensitivity, the project based on luminescent organic linkers coordinated to metal ions, is aimed at constructing metal organic frameworks. Introducing the luminescent organic linkers into the frameworks makes it possible for the material to have luminescence and porosity simultaneously. The project, in order to reveal the synthesis law and relationship between structure and property, discover and set up synthesis methods for molecular functional materials, and deep apprehend the physical essence of the relationship between structure and property of the materials, is required to do research on designing, synthesis and the relationship between structure and property, as well as the luminescent discoloration effect along with its underlying causes. Based on that, we can explore the potential application of metal complexes as luminescence sensors, opening new research idea in luminescence sensors.
