Organization of Zeolite Microcrystals (Zeolite Supercrystal Research)       

The ability to rationally assemble complex structures from modular components of various sizes is an essential part of life and key to success for the materials chemistry of the new millennium. Chemists have acquired enough ability to organize subnanometer building blocks such as atoms and small molecules into complex structures. With the dawn of a new century, chemists have begun including nanobuilding blocks (1-10 nm) into their pools of building blocks. However, micrometer-sized building blocks have not yet been considered as a class of building blocks despite the fact that the ability to organize them will make materials chemistry flourish.


 



Using zeolite microcrystals as model microbuilding blocks, our center has developing the methods of organizing them into two- (2D) and three-dimensionally (3D) organized structures. The use of zeolite microcrystals as microbuilding blocks has additional merit since each zeolite microcrystal has millions of regularly spaced nanochannels and billions of nanopores which can be filled with a variety of functional molecules or nanoparticles. Therefore, our center has intended to not only develop the ‘chemistry of microbuilding blocks’ but also open a gateway to application of zeolites as advanced materials.

Major research
• Assembly of zeolite microcrystals into uniformly aligned monolayers and multilayers
• Application of the organized zeolite microcrystals (supercrystals)
• Development of zeolite-based 2nd- and 3rd-order nonlinear optical (NLO) materials
• Photovoltaic Application of Quantum Dot-Incorporating Zeolite Film
• Synthesis of new zeolite crystals 
• Development of molecular sieving membranes (CO2 from the air, H2 from the mixture with O2)
