利用发光金属有机框架（LMOFs）可调节的孔道结构吸附特定的客体，来制备性能独特的复合发光材料（guest@LMOFs），已成为化学领域的研究热点之一。然而，该类材料依然存在客体封装效率不高、组装上缺乏可控性、性能调控规律不够清晰等问题，因此，如何构筑高效、稳定、性能可控的guest@LMOFs复合材料仍需更加深入的研究。本项目计划：1）在LMOFs孔道中设计引入多种相互作用（如配位作用、氢键作用、堆积作用、静电引力），并据其不同的作用特点，分析建立模型，进而为主体框架的结构设计和相应客体类型的选择提供指导，提高封装效率，实现该类材料的可控组装；2）基于我们新合成的一类具有封闭孔的LMOFs，进一步通过“一锅法”策略，实现高效、稳定的客体封装，探索有效构筑该类材料的新方法；3）通过对材料发光性能的深入研究，总结各种主客体相互作用对材料性能的影响规律，建立“框架+客体-发光性能”构效关系。

It has been an important part of study in chemistry field for utilizing the regulable pore structures of Luminescent Metal-Organic Frameworks (LMOFs) to adsorb specific guest so that preparing composite luminescent materials (guest@LMOFs) with unique properties. However, there still exist a series of problems of this kind of materials like low encapsulation efficiency, lack of controllability of the assembly, and uncertainty of property modulation. As a result, more deep studies are still needed for the rational design and synthesis of stable guest@LMOFs materials with high efficiency and controllable properties. In this project, to solve these problems, 1) we will design and introduce various kinds of interactions (e.g. coordination, hydrogen bonding, stacking, electrostatic attraction) into pores of LMOFs, and based on analyzing of their different characteristics, complete the mechanism modelling of interactions, which could provide guidance for the structure design of host frameworks and guest selection of corresponding type, thus enhancing the encapsulation efficiency and further realizing the controllable assembly of guest@LMOFs composite materials; 2) base on a class of new obtained LMOFs with closed pores, guest encapsulation with high efficiency and stability will be further realized by using a “one-pot strategy”, and effective new method for the construction of these materials will be explored; 3) through deep study of the luminescent properties of obtained materials, we will summarize the influence discipline of various host-guest interactions to material properties, and then, build the relationship of “framework + guest – luminescent property”.
