有机纳米粒子-金属有机框架化合物异质纳米结构的可控构筑及功能调控

将两个或多个功能组分通过可控集成来构建具有集合特性及先进性能的复合纳米结构，一直是实现纳米材料多功能化及在更广泛领域应用的一条切实可行的途径。然而，目前报道的复合纳米结构的构建基元主要局限于无机纳米粒子，尤其是与金属有机框架化合物复合构建的异质纳米结构，很少有基于有机纳米粒子的报道，虽然其具有更高结构可调性、反应性和加工性。本项目拟将有机纳米粒子引入到金属有机框架化合物制备体系，通过构建基元的精确设计及对基元间相互作用的调控，实现相关异质纳米结构的可控构筑，揭示其形成机制、组分间的物性协同效应及因基元协同和性能融合而被赋予的优异性能或新功能，深入理解结构与性能间的构效关系，并在功能调控的基础上初步探索其在传感、柔性器件等领域的潜在应用价值，促进对有机纳米粒子-金属有机框架化合物异质纳米结构的全面认识，为丰富异质纳米结构材料体系并进一步实现其在更广泛领域的应用提供依据与参考。

Controllable integration of two or more functional components into advanced materials to obtain composite materials with collective properties and improved performance has always been a practical way to obtain multifunctional materials for wider applications in many fields. However, to date, most nanoparticles combined with metal-organic frameworks to form heteronanostructures are inorganic nanoparticles, and scarce examples are fabricated on the basis of organic nanoparticles though they have higher structural tunability, reactivity and processability than inorganic nanoparticles. In this project, organic nanoparticles will be introduced into the preparation system of metal-organic frameworks. Through precise design of the constructive units and precise regulation of the interactions among them, heteronanostructures based on organic nanoparticles and metal-organic frameworks will be constructed controllably. The formation mechanism and the effect of property synergy will be investigated, and meanwhile, the excellent performance or new functions conferred by function synergy will be revealed. Furthermore, the application potential of this type of heteronanostructures based on organic nanoparticles and metal-organic frameworks will be explored in many fields especially in sensing and flexible devices. The applicant hopes that this research project not only can promote a comprehensive understanding of heteronanostructures constructed by organic nanoparticles and metal-organic frameworks but also can serve for enrichment of the material system of heteronanostructures and achievement of wider applications.
