Our project is consisting of the following steps: 1) selection of suitable molecular assemblies as templates for sol-gel transcription 2) optimization of conditions for sol-gel transcription 3) estimation of physical properties of the prepared organic-inorganic composite materials 4) feedback for the molecular design on the basis of the obtained physical properties.For this purpose, we focused on the dimensions of the composites. First, electronically and optically active aromatic compounds such as porphyrin and triphenyrene as the core and amide and urea groups for the gel-forming segment which strongly induce one-dimensional assembly. Diblock copolymers are the second target as they form two-dimensional periodic structures, which, in some cases, are suitable template for two-dimensional sol-gel transcription. Metal complexes and fullerene and carbon nanotube are also donated to this system. We have conducted various spectroscopic analyses and microscopic analyses as well as X-ray crystallographic and powder X-ray analyses to obtain structural information and physical properties inherent to these materials. Notably, DNA can also be processed by this system. This achievement implies that volatile bio-information can be memorized by sol-gel process as stable inorganic materials.

本课题主要包括以下几个步骤：1）选择合适的分子组装体作为溶胶-凝胶转录模板; 2）优化溶胶-凝胶转录条件; 3）估算所制备的有机-无机复合材料的物理性质; 4）根据所得的物理性质反馈分子设计。首先，电子和光学活性的芳香族化合物，如卟啉和三苯基作为核心和酰胺和脲基团的凝胶形成部分，强烈诱导一维组装。二嵌段共聚物是第二个目标，因为它们形成二维周期性结构，在某些情况下，这是二维溶胶-凝胶转录的合适模板。金属配合物和富勒烯和碳纳米管也捐赠给这个系统。我们进行了各种光谱分析和显微分析以及X射线晶体学和粉末X射线分析，以获得这些材料固有的结构信息和物理特性。值得注意的是，DNA也可以通过该系统进行处理。这一成果意味着挥发性的生物信息可以通过溶胶-凝胶过程作为稳定的无机材料来存储。
