1. A composition of matter comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of hexagonal symmetry comprising mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material, wherein the long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern including peaks occurring at 20 angles less than about 6°, and whereby long-range mesoporous ordering of hexagonal symmetry is observable by microscopy including mesopore periodicity repeating over a length of greater than about 50 nm.
 
8. A composition of matter comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of hexagonal symmetry comprising mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material, wherein at least a portion of the mesopores contain micelles of supramolecular templates shaped to induce mesoporous ordering of hexagonal symmetry, and wherein the supramolecular templates possess one or more dimensions larger than dimensions of micropores of the crystalline microporous material to constrain diffusion into micropores of the crystalline microporous material, wherein the dimensions relate to a head group of a supramolecular template, a tail group of a supramolecular template, or a co-template arrangement that constrain diffusion into micropores of the crystalline microporous material, and wherein if the crystalline microporous material possesses micropores of various dimensions, the one or more dimensions of the supramolecular templates are larger than the largest micropores of the crystalline microporous material.
