機能性無機ナノ粒子のサイズ・形態制御液相合成とハイブリッド材料開発への展開
Size- and Shape-Controlled Synthesis of Functional Inorganic Nanoparticles and Application to Develop Self-Organized Hybrid Materials

研究の背景 Background

ハイブリッド材料は,例えば有機物の柔軟性や無機物の剛直性など,相反する機能や性質を相乗的に示すことが期待される材料です.しかしながら,従来の開発手法は,混練など,有機物・無機物のマクロな混合により,それぞれの性質を相補的に利用することに重点が置かれています.そのため,革新的な機能の創製に繋がり難く,分子・ナノレベルでの物質の融合に着想した材料開発に注目が集まっています.

Hybrid material is a promising material to show synergy functions such as fluidity of organics and hardness of inorganics. However, most of the previous studies have been carried out by simple mixing with organic and inorganic functional materials. In this regard, hybrid material, obtained by nano- or molecular-level interactions between organic and inorganic materials, has attracted great deals of attentions for the introduction of novel functions.

研究の目標 Outcome

液相法により,様々な機能性無機ナノ粒子をサイズ・形態制御しつつ合成する手法の開発を行っています.一方で,自己組織性や刺激応答性を有する機能性有機分子をデザイン・合成しています.無機・有機双方の精密合成に関わる研究知見を活用し,無機-有機ヘテロ界面接合を構築することで,無機・有機双方の機能を相乗的に示すハイブリッド材料を開発します.

One of the main subjects of our study is to develop liquid-phase synthetic methods of functional inorganic nanoparticles preciously controlled in size and shape. On the other hand, we focus on design and synthesis of functional organic materials with self-organizing and stimuli-responsive abilities. By the hybridization of our established precious synthetic chemistry in fields both of inorganic and organic functional materials, we are creating novel-type of hybrid materials with synergistic function both of inorganic and organic matters.
