多孔超分子离子骨架材料（SPINs）：新型有机多孔材料的实用制备及温室气体吸附研究

随着全球气候变化、环境和能源问题的加剧，二氧化碳(CO2)和六氟化硫(SF6)等温室气体的捕捉与分离已成为全世界关注的研究热点。而寻找对气体具有良好吸附性能的先进纳米多孔材料成为解决问题的关键。近年来涌现出许多结构新颖的纳米多孔材料，如 MOFs, COFs, PAFs等。但是，制备过程的繁琐和耗时限制了其进一步的应用。本项目基于申请人对NO2-PAFs、NN-POP-1和SPIN-1等的前期研究基础，拟采取具有高度刚性的四磺酸和可商业购买的多元有机胺发生酸碱中和反应，快速的质子转移反应使得磺酸根阴离子与有机铵盐之间的静电作用形成离子骨架结构，从而实现多孔性超分子离子骨架材料(SPINs)的简易和大量制备，并将其应用于CO2和SF6等温室气体吸附中。与大多数现有的有机多孔材料相比，SPINs的结构精确，结构多样，并可实用制备，对于揭示孔道的形成和控制机制，进一步指导材料的设计大有裨益。

With the issue of climate change, envionment and energy, the adsorption and seperation towards CO2 and SF6 became more and more popular in materials community. The key to get highly performed materials for gas adsorption is to develop excellent advanced nanoporous organic polymers. Although many novel porous materials such as MOFs, COFs and PAFs has been developed, the tedious procedure for making those materials has prevented the nice POPs for further application. This project proposed a practical synthesis of SPINs based on the complex between the rigid tetrasulfonic acid and commercially amines. A fast proton transfer occured, the strong electrostatic interaction between the resulting sulfonate and ammonium will lead to self-asembly guided by rigid monomers, and thus afford the well-defined SPINs. The mechanism to control the porosity of SPINs and CO2 and SF6 uptakes will be disclosed, and the design principle for materials towards gas adsorption will be proposed.
