摘　　要：利用溶胶-凝胶聚合过程人工模拟生物矿化进程的技术,已经融入无机材料和超分子有机化学的研究领域。小分子有机凝胶因子在溶剂中发生自组装,形成多种形态的有机凝胶超分子结构,以其为模板,经过溶胶-凝胶过程,可以诱导转录形成各种形态的纳米材料。本文介绍了利用有机凝胶因子自组装结构为模板制备形态可控无机材料的研究进展及模板结构诱导转录的两种可能机制。The design of artificial models of ＂biomineralization＂ processes utilizing sol-gel polymerization has become a research branch of inorganic materials and supramolecular organic chemistry. The self-assembled superstructures of low molecular weight organic gelators are used as versatile building blocks in organogels and as templates for sol-gel transcription into nano-structural materials. The use of self-assembled organic superstructures in the creation of novel inorganic materials with controlled morphologies is focused on and two mechanisms for forming nano-structural materials by the template method are illustrated in this paper.
