The field of porous, inorganic materials is experiencing explosive gro
wth, as is shown by more than 6000 literature citations since 1994 alo
ng with numerous recent symposia and workshops that have been devoted
to this topic. Much of the recent interest has been fueled by new synt
hetic strategies, such as 'supramolecular templating: that have enable
d precise engineering of pore size, shape, and connectivity on the mes
oscopic scale. In general, template-based approaches involving the coo
perative organization of organic-inorganic assemblies as intermediates
are emerging as a promising conceptual basis for future developments
in the field oi porous inorganic materials, such as the synthesis oi h
ierarchical morphologies that mimic the intricate structures found so
often in nature.
