有机-无机纳米复合材料的研究在当前纳米科学技术的发展中占有重要地位,开创了材料与催化科学研究的新纪元。自从10年前首次合成纳米孔无机材料MCM-41至今,该领域研究不断深入,已展现出广阔的应用前景。当客体有机分子分散于纳米孔道内部时,其分子性质将产生明显变化。本文结合作者近期研究成果,力图从实验与理论两方面阐明在纳米复合体系中客体分子性质变化的原因。 The research of organic-inorganic nanocomposites occupies an important position in the current development of nanoscience and technology and has opened up a new era of scientific research on materials and catalysis. Since the first synthesis of nanoporous inorganic material MCM-41 10 years ago, the research in this field has been deepened and has shown broad application prospects. When the organic molecules are dispersed in the interior of the nanopore, the molecular properties will change significantly. In this paper, the author’s recent research results, trying to clarify both the experimental and theoretical aspects of the reasons for the change in the molecular properties of nanocomposites.
