基于“主-客体”化学的考虑，采用“软模板法”和“硬模板法”合成非硅介孔材料时，突出了客体分子之间的相互作用。利用广义的“酸碱对”概念，选择合适的客体分子，制备出具有不同结构的高度有序的介孔金属氧化物、磷酸盐和硼酸盐。介观有序的聚合物和具有均匀大孔径的碳骨架是由有机表面活性剂与有机客体的自组装得到的。正确地构建客体单元和装饰主体在复制有序的非硅单晶纳米阵列中是重要的。展望了合成有序介孔非硅质材料的潜在可能性。
On the basis of the consideration of "host-guest" chemistry, the interactions between guest molecules are highlighted in the synthesis of nonsiliceous mesoporous materials by the "soft-template" and "hard-template" approaches. A generalized "acid-base pair" concept is utilized in selecting appropriate guest molecules to prepare highly ordered mesoporous metal oxides, phosphates, and borates with diversified structures. Mesoscopically ordered polymer and carbon frameworks with uniformly large pore sizes are derived from the self-assembly of an organic surfactant with an organic guest. Properly building the guest unit and decorating the host are important in replicating ordered nonsiliceous single-crystal nanoarrays. Outlooks on the potential possibilities for synthesizing ordered mesoporous nonsiliceous materials are presented as well.
