Chemical Energy and Information Conversion by Utilizing Molecular Synchronization of Polymer Networks

在结构由弱分子间相互作用（如氢键、离子偶极子、静电和疏水相互作用）之间的平衡决定的聚合物网络中，经常观察到网络聚合物中对官能团的微小波动在数量上转化为不同的波动，这种波动以空间和时间同步的方式在整个网络中传递。换句话说，弱相关聚合物网络不仅是一个结构网络，而且是一个传递和转换能量和信息的网络。本研究旨在通过揭示分子水平上的“分子同步”，为设计化学能和信息转换的新材料系统提供一种新的方法。在本研究中，主要研究了以下三个项目：乙烯基单体在离子液体中原位聚合形成“离子凝胶”及其在化学能转换中的应用吩噻嗪标记聚乙二醇修饰葡萄糖氧化酶的电子转移反应及其高效化学信息转化以最紧密的二氧化硅胶体晶体为模板制备的“结构彩色凝胶”，其结构颜色随外界刺激而变化。

In polymer networks whose structures are determined by the balance between weak intermolecular-interactions, such as hydrogen bonding, ion-dipole, electrostatic, and hydrophobic interactions, it is frequently observed that a tiny fluctuation toward functional groups in the network polymers is quantitatively converted to a different fluctuation, which is transferred, in a spatially and chronologically synchronized manner, over the whole networks. In other words, the weakly correlated polymer networks function not only as a structural network but also as a network for transferring and converting energy and information. This research has been aimed at proposing a new methodology for the design of new materials system for chemical energy and information conversion by revealing "molecular synchronization" in the molecular level. In this research, the following three projects have been studied1. In-situ polymerization of vinyl monomers in ionic liquids to form "ion gels" and their utilization in chemical energy conversion.2. Electron transfer reaction of glucose oxidase modified with phenothiazine-labeled PEG for efficient chemical information conversion.3. "Structurally-colored gels" prepared by using closest packing silica colloid crystals as a template and their structural color change in response to external stimuli.
