Journal ArticleDOI
Carbon dioxide capture and efficient fixation in a dynamic porous coordination polymer
Pengyan Wu,Yang Li,Jia-Jia Zheng,Nobuhiko Hosono,Nobuhiko Hosono,Ken-ichi Otake,Jian Wang,Yanhong Liu,Lingling Xia,Min Jiang,Shigeyoshi Sakaki,Susumu Kitagawa +11 more
TL;DR: A dynamic porous coordination polymer material with local flexibility, in which the propeller-like ligands rotate to permit effective CO2 trapping, and subsequent CO2 cycloaddition to epoxides is demonstrated.
Journal ArticleDOI
Single-Atom-Based Vanadium Oxide Catalysts Supported on Metal–Organic Frameworks: Selective Alcohol Oxidation and Structure–Activity Relationship
Ken-ichi Otake,Yuexing Cui,Cassandra T. Buru,Zhanyong Li,Joseph T. Hupp,Omar K. Farha,Omar K. Farha +6 more
TL;DR: Crystallographic and variable-temperature spectroscopic studies revealed that the incorporated vanadium in Hf-MOF-808-V changes position with heat, which led to improved catalytic activity.
Journal ArticleDOI
Increased Electrical Conductivity in a Mesoporous Metal-Organic Framework Featuring Metallacarboranes Guests.
Chung Wei Kung,Ken-ichi Otake,Cassandra T. Buru,Subhadip Goswami,Yuexing Cui,Joseph T. Hupp,Joseph T. Hupp,Alexander M. Spokoyny,Omar K. Farha,Omar K. Farha +9 more
TL;DR: Nickel(IV) bis(dicarbollide) is incorporated in a zirconium-based metal-organic framework (MOF), NU-1000, to create an electrically conductive MOF with mesoporosity, which permits the further incorporation of other active species in the remaining mesopores.
Journal ArticleDOI
A Flexible Metal–Organic Framework with 4-Connected Zr6 Nodes
Yuanyuan Zhang,Yuanyuan Zhang,Xuan Zhang,Jiafei Lyu,Ken-ichi Otake,Xingjie Wang,Louis R. Redfern,Christos D. Malliakas,Zhanyong Li,Timur Islamoglu,Bo Wang,Omar K. Farha,Omar K. Farha +12 more
TL;DR: A flexible Zr-MOF named NU-1400 comprising 4-connected Zr6 nodes and tetratopic linkers is presented, which exhibits guest-dependent structural flexibility with up to 48% contraction in the unit cell volume as evidenced by single-crystal X-ray diffraction studies.
Journal ArticleDOI
A porous, electrically conductive hexa-zirconium(IV) metal–organic framework
Subhadip Goswami,Debmalya Ray,Ken-ichi Otake,Chung Wei Kung,Sergio J. Garibay,Timur Islamoglu,Ahmet Atilgan,Yuexing Cui,Christopher J. Cramer,Omar K. Farha,Omar K. Farha,Joseph T. Hupp +11 more
TL;DR: In this article, a porous zirconium-node-containing MOF, NU-901, can be rendered electronically conductive by physically encapsulating C60, an excellent electron acceptor, within a fraction of the diamond-shaped cavities of the MOF.
