The design of the mesoporous molecular sieves with cage-, and cylindrical-like structures makes these materials promising candidates in environmental and industrial applications. If the mesostructures are fabricated into transparent monoliths that are hard, free of cracks, and macroscopic in scale, then their utilities can be widely expanded. Here we developed a synthesis strategy, instantly direct templating liquid crystal phase, which is simple in terms of fabrication time (within minute) and in composition domains, and is efficient to design mesostructures with cage and cylindrical-like monoliths, large-sized glass, thick-walled, and uniform mesopores. A family of monolithic structures was feasibly fabricated in large ordered domains by using triblock copolymer templates. This approach leads to retention of the ordered structures under extreme hydrothermal conditions for a month or even longer.
