| Abstract
| - On the basis of the consideration of “host−guest” chemistry, theinteractions between guest molecules are highlighted in thesynthesis of nonsiliceous mesoporous materials by the “soft-template” and “hard-template” approaches. A generalized “acid−base pair” concept is utilized in selecting appropriate guestmolecules to prepare highly ordered mesoporous metal oxides,phosphates, and borates with diversified structures. Mesoscopicallyordered polymer and carbon frameworks with uniformly large poresizes are derived from the self-assembly of an organic surfactantwith an organic guest. Properly building the guest unit anddecorating 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.
