Prof. Hiaoka obtained his Ph. D. at Tokyo Institute of Technology in 1998. He then trained as a postdoctoral fellow with Professor M. Fujita at Institute for Molecular Science. He was appointed Assistant (2001), Associate (2007), and Full Professor (2010) at The University of Tokyo, where his group explored discrete artificial supermolecules (molecular ball bearing and metallo-capsules etc.) based on self-assembly of novel multi-monodentate ligands and transition metal ions. His current research efforts are focused on developing gear-shaped amphiphiles that can assemble into discrete capsule structures with the aide of van der Waals interaction and hydrophobic effect. Van der Waals interaction plays an important role in biological system. However, this interaction is hard-to-use for constructing precise assembled molecules in artificial system due to poor directionality and weakness. In 2008, Hiraoka's group developed a gear-shaped amphiphile with indented hydrophobic surface area and revealed that this molecule assembled into a box-shaped hexamer in solution. His group currently studies (i) development of novel amphiphiles for constructing various structures, (ii) molecular recognition, molecular arrangement, and reaction in the resulting confined nano-space of the molecular capsule. Hiraoka's group uses organic, inorganic and supramolecular synthetic methods to create new functional molecules.
