Research Topics

We enjoy 'Crystal Engineering' using perfluoroarene-substituted compounds. The research topics are as follows,

Guest encapsulation of non-porous crystals of perfluorinated metal complex
Chem. Eur. J., 2020, 26, 5051-5060; CrystEngComm, 2014, 16, 8805-8817; CrystEngComm, 2007, 9, 215-217.

Flexible hosts were designed by fully and partially fluorine-attached coordination complexes, which encapsulated several organic guest molecules in their crystals.

Gas adsorption of non-porous crystals using quadrupole moments induced by fluorination
Dalton Trans., 2019, 48, 9062-9066; CrystEngComm, 2017, 19, 6263-6266.

Fully fluorine-attached coordination complexes show remarkable and selective gas adsorption in the molecular crystalline states.

Dynamic Transformation between Pseudopolymorphs of a Fully Fluorinated Complex
Cryst Growth Des., 2014, 14, 3169-3173.

Pseudopolymorphs were obtained from the fully fluorinated complex with mesitylene and the quantitative transformation was observed by shaking. The crystals also encapsulated aromatic molecules in their uniform cavities.

Cross-Assembly of Two b-Diketonate Complexes through Arene–Perfluoroarene Interactions
Angew. Chem. Int. Ed., 2007, 46, 7617-7620.

Two metal complexes are alternatively arrayed closely to van der Waals contacts via arene-perfluoroarene interaction to give 1:1 cocrystals as one-dimensional metal wires.

Crystallographic studies for inorganic and organic molecules
Inorganic: CrystEngComm, 2020, 22, 3090-3094; Polyhedron, 2020, 192, 114825.
Organic: Acta Cryst., 2019, C75, 265-270; Crystals, 2019, 9, 175, 1-12.

Focusing on the dynamic structural changes, adsorption phenomena, and physical properties of molecular crystals, we are crystallizing and functionalizing discrete aromatic compounds. We aim to understand the crystal structure and intermolecular interaction in relation to DFT calculations.
