金属硅倍半氧烷的合成及其应用研究进展
Research Progress on the Synthesis and Application of Metallic Polyhedral Oligomeric Silsesquioxane
摘要
Abstract
Based on the types of metal elements,this paper introduced in detail the various cage-like metallic silsesquioxane and its precise molecular structure of almost all metal elements in the existing peri-odic table of elements that have been successfully synthesized.From the point of view of synthesis pro-cess,the research process of preparation methods of cage-like metallic silsesquioxane through several inter-national and domestic research groups in recent two decades was reviewed.With the successful synthesis of incomplete polycondensation cage-like metallic silsesquioxane,it was easy to synthesize cage-like metal-lic silsesquioxane containing different metal elements via using its silicon hydroxyl group and metal to form coordination bonds.About the preparation method of cage-like metallic silsesquioxane,one method was almost all metal elements could be introduced into the cage structure of silsesquioxane by the"corner-cap"preparation method,in which multivalent metal ions could act as missing vertices in the cage,thereby pre-paring cage-like metallic silsesquioxane with precise molecular structure;another main synthesis method was to use a high concentration of inorganic bases and alkoxysilanes to react,and further adding chlori-nated multivalent metal salts to prepare cage-like metallic silsesquioxane containing Cu,Co,and Fe;in addition,the advantages/disadvantages of various synthesis methods for cage-like metallic silsesquioxane were briefly pointed out.Finally,the application status of various cage-like metallic silsesquioxane in the field of catalysis and flame retardant was introduced in detail,and the recent research emphasis of cage-like metallic silsesquioxane and the future development direction were presented.关键词
