Professor Ryotaro Matsuda's research lab specializes in the design and synthesis of functional porous coordination polymers (PCPs) and metal-organic frameworks (MOFs), with a focus on their structural flexibility, guest-induced framework transformations, and applications in gas separation, catalysis, and proton conduction. The lab explores how dynamic structural responses—such as pore contraction or framework rearrangement—can be harnessed for selective adsorption of small molecules like CO and benzene, as well as for enhancing catalytic and transport properties. A key research direction involves engineering metal sites and functional groups (e.g., sulfonic acid) to achieve high selectivity and activity under mild conditions, including low humidity environments. The lab combines advanced in situ characterization techniques, such as synchrotron X-ray powder diffraction, with precise control over framework topology and interpenetration to tailor materials for sustainable chemical processes and energy-related applications.

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable pores, and we present crystallographic evidence that CO molecules can coordinate with copper(II) ions. The unprecedented high selectivity was achieved by the synergetic effect of the local interaction between CO and acc
A MIL-101-based porous coordination polymer (PCP) containing sulfonic acid groups is synthesized. The sulfonic groups are exposed on the pore surface and act as strong Brønsted acid sites. This solid acid PCP catalytically hydrolyzes cellulose into mono- and disaccharides and shows high durability in the catalytic reaction. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made
In situ synchrotron X-ray powder diffraction patterns of porous coordination polymers [[Cu(2)(pzdc)(2)(bpy)].G] have been measured (pzdc = pyrazine-2,3-dicarboxylate, bpy = 4,4'-bipyridine) (where G = H(2)O for CPL-2 superset H(2)()O, G = benzene for CPL-2 superset benzene, and G = void for the apohost). The structures of apohost and CPL-2 superset benzene were determined from Rietveld analysis. Adsorption of benzene in the channels induced a remarkable contraction in the crystal (b axis; 6.8%,
Transforming jungle gyms: Structural flexibility and sorption behavior can be tuned by controlling the degree of interpenetration of 3D porous coordination polymers (PCPs). The architectural connectivity of PCPs, even those that are composed of the same chemical components, has a significant impact on the structural flexibility and sorption behavior, which was confirmed by coincident XRPD/adsorption measurements.
Three new sulfonated porous coordination polymers (PCPs)/metal-organic frameworks (MOFs) have been synthesized using solvothermal methods. These PCPs possess porous structures with non-coordinating sulfonic acid groups or sulfonate with dimethyl ammonium cations and exhibit high proton conductivity at a low humidity of 60% RH (relative humidity) at ambient temperature.
