Outline

With world's focus on environment and energy issues, our group aims to establish a novel principle of material sciences addressing these problems, through the development of unprecedented functional materials with precisely controlled structure and properties at molecular to nanoscale levels. The main research subjects include (1) the development of novel organic catalysts consisting only of ubiquitous elements for high efficient water photolysis, (2) the development of the solution-processable organic ferroelectric materials for the application to memory devices, and (3) the development of precise supramolecular polymerizations.

Results

Chain-growth supramolecular polymerization

Over the last decade, significant progress in supramolecular polymerization has had a substantial impact on the design of functional soft materials.   However, despite recent advances, most studies are still based on a preconceived notion that supramolecular polymerization follows a step-growth mechanism.  We recently realized the first chain-growth supramolecular polymerization by designing metastable monomers with a shape-promoted intramolecular hydrogen-bonding network.  The monomers are conformationally restricted from spontaneous polymerization at ambient temperatures but begin to polymerize with characteristics typical of a living mechanism upon mixing with tailored initiators.  The chain growth occurs stereoselectively and therefore enables optical resolution of a racemic monomer.  We believe that it may give rise to a paradigm shift in precision macromolecular engineering.
