The Primary impetus for developing a mechanistic understanding of zeolite synthesis is the ultimate goal of the rational design and synthesis of novel zeolite pore architectures. To that end，the mechanisms by which the geometries of organicstructure-directing agents are translated into the product pore architectures in the syntheses of high-Silica and intermediate-Silica containing zeolites are discussed Two different mechanisms of structure direction and self-assembly via the fomation of extended inorganic/organic composite structures or of purely-inorganic structures are proposed for the two different classes of materials， respectively. By considering issues such as hydrophobic hydration bebavior of the structure-directing agents for the synthesis of new zeolite structures may be possible Extension of the zeolite assembly process to the use of organic molecules that can form micelles can yield ordered mesoporous materials like MCM-41 and MCM-48. A unifying picture of the assembly processes occurring in the Syntheses of micro-and mesoporous materials is presented.
