Abstract

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.
