配位聚合物的化学近年来得到了广泛的发展，提供了各种各样的结构，这些结构是由各种分子结构单元构建的，它们之间具有不同的相互作用。下一个挑战是通过框架的多孔性对这些结构进行化学和物理功能化。作者首次合成了一种新型的与甲烷储存相关的多孔材料，开发了既能储存气体又能分离气体的功能，其容量高于常规材料。他已经实现了（1）首次观察到固体中分离的氧分子，一维梯形结构与主体通道对齐，这使得更好地理解纳米通道中的吸附现象，然后导致新的纳米技术，（2）与非常相似的分子二氧化碳相比，乙炔分子具有极高水平的选择性吸附，在多孔配位聚合物的功能化表面上，和（3）在环境温度下对超临界气体具有特定的开门压力的柔性结晶多孔框架，其将在气体分离和传感器中找到应用。作者完成的工作的标志是用于存储和分离的多孔材料的创新，建立其化学以深入了解吸附现象，并引入一个新的概念，灵活的框架，提供独特的功能。
The chemistry of the coordination polymers has in recent years advanced extensively, affording various architectures, which are constructed from a variety of molecular building blocks with different interactions between them. The next challenge is the chemical and physical functionalization of these architectures, through the porous properties of the frameworks. The author first synthesized a novel porous material relevant to methane storage and developed the functions not only as gas storage but also separation with the capacity higher than conventional materials. He has attained (1)the first observation of detached oxygen molecule in solid, 1D ladder structure aligned to the host channel, which gives a better understanding of adsorption phenomena in nano-channel and then, lead to a novel nano-technology, (2) extremely high levels of selective sorption of acetylene molecules as compared to a very similar molecule, carbon dioxide, onto the functionalized surface of a porous coordination polymers, and (3) flexible crystalline porous frameworks having a specific gate-opening pressure for super critical gases at ambient temperature, which will find applications in gas separation and sensors. The hallmark of work accomplished by the author is innovation of porous materials for storage and separation, establishing its chemistry for in-depth understanding of sorption phenomena and introducing a new concept, flexible framework, which provide unique functions.
