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

在其结构由弱分子间相互作用（如氢键、离子偶极、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朝向官能团的微小波动定量地转化为不同的波动，该波动以空间和时间同步的方式在整个网络上转移。换句话说，弱关联聚合物网络不仅作为结构网络，而且作为传递和转换能量和信息的网络。本研究旨在从分子水平上揭示“分子同步”现象，为化学能量和信息转换新材料体系的设计提供一种新的方法。在本研究中，研究了以下三个项目1。乙烯基单体在离子液体中原位聚合形成“离子凝胶”及其在化学能量转换中的应用.吩噻嗪标记PEG修饰葡萄糖氧化酶的电子转移反应，实现高效的化学信息转换.通过使用最紧密堆积的二氧化硅胶体晶体作为模板制备的“结构着色凝胶”，并且其结构颜色响应于外部刺激而改变。

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.
