This work explores methods for the synthesis of polyhedral oligomeric silsesquioxanes (POSS) and their use in the design of porous materials. Specifically, this work focuses on the octameric R8Si8O12 due to its unique cubic geometry, thermal stability, and multi-functionality. The Si8O12 cage in POSS offers a rigid inorganic core on which additional organic functional groups can be placed in strategic locations. By tailoring the number and nature of these organic arms it is possible to generate silicious ligands previously unavailable for the framework materials. Three different POSS derivatives possessing cyano, pyridyl, and hydroxy functionalities are synthesized and applied as nodes for the preparation of extended materials using hydrogen bonding and metal-ligand interactions.
