The chemistry of porous coordination networks has undergone explosive growth in the last decade, because of the fascinating features such as gas sorption/separation/storage, molecular recognition, drug delivery, catalysis, and so on. We demonstrated that a pore of porous materials also can be used as crystalline molecular flask in order to observe not only a reaction but also reactive intermediates by X-rays [1-5]. Thanks to the high flexibility in design, a number of porous coordination networks were prepared and analyzed by single crystal X-ray crystallography. During self-assembly of coordination networks, there are many intermediate states, some of which can be trapped kinetically.
The most of coordination networks reported in references belong to thermodynamically stable ones. However, in this talk, I would like to focus on kinetically-assembled porous coordination networks [6-10]. The kinetic study of porous coordination networks unlike zeolite is an unexplored field, because of difficulties in ab initio powder structure determination. Our recent progress will be reviewed.
