Abstract

is an associate professor at the department of basic science, The University of Tokyo. She received her PhD in applied chemistry from The University of Tokyo (2002). She has worked as a postdoc and assistant professor at the department of applied chemistry, The University of Tokyo (Prof. Mizuno group) and moved to the current position (2009 Oct). She has also worked as a JST-PRESTO researcher "Hyper-nanospace design toward innovative functionality" (20132017). Her work focuses on the synthesis of functional solid-state materials based on polyoxometalates. Yuto Shimoyama is a PhD student at The University of Tokyo. He received his Bachelor's degree (2017, catalyst and surface science group) and master's degree (2019, Prof. Kanbara group) in engineering from University of Tsukuba. His current research focuses on the synthesis of porous ionic crystals and their catalytic applications at the Uchida group.

Syntheses, Polymorphic Transformations, and Functions of Ionic Crystals Based on Mononuclear Bismuth(III) Complexes and Polyoxometalates

“…[8,9] Polymorphism, [10][11][12] which is defined as the ability of a solid to crystallize into different structural forms, is frequently utilized in crystal engineering to control the physical or chemical properties of solids by changing the packing arrangements of the building blocks. In particular, polyoxometalates (POMs), [13][14][15][16][17][18][19][20] which are anionic metal oxide clusters composed of high-valence transition metals, have been used as building blocks in crystal engineering. [21] In particular, α-Kegginand α-Dawson-type POMs with high molecular symmetries of T d and D 3h , respectively, have been a popular motif.…”

Single-Crystal-to-Single-Crystal Cluster Transformation in a Microporous Molybdoarsenate(V)-Metalorganic Framework

“… 4 , 5 Thus, these systems represent promising candidates for applications in fields like gas sorption and separation, ion-exchange, sensing, and catalysis. 6 Beyond the ionic crystals in which the nonefficient packing between macroanions and bulky [M 3 O(OOCR) 6 (L) 3 ] + cations generates large structural voids, 7 , 8 different synthetic strategies have been followed to prepare extended POM-based porous solids. The direct linkage of cluster units through additional metal cations can lead to fully inorganic porous architectures with high thermal and chemical stabilities.…”

Merging the chemistry of metal–organic and polyoxometalate clusters to form enhanced photocatalytic materials

“…In fact, there are many examples in the literature where the incorporation of POMs into the pores of MOFs has increased the catalytic performance of the latter. 11,12 Last but not least, the packing of such macro-ionic entities is expected to render a meaningful amount of void volume or pores in the crystal structure, 13 which might increase the surface area of the catalyst. Keeping all this in mind, we have selected a Keggin type polyoxometalate of the formula [SiW 12 O 40 ] 4− (W 12 ) due to its high negative charge, size and intrinsic photocatalytic properties.…”
