Abstract
A composition of matter is provided comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic symmetry. The composition possesses mesopores having walls of crystalline microporous material and a mass of mesostructure between mesopores of crystalline microporous material. Long-range ordering is defined by presence of secondary peaks in an X-ray diffraction (XRD) pattern and/or cubic symmetry observable by microscopy.

A composition of matter comprising hierarchically ordered crystalline microporous material having well-defined long-range mesoporous ordering of cubic 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 of cubic mesophase symmetry 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 is observable by microscopy including mesopore periodicity repeating over a length of greater than 50 nm.
