3. We should be able to lay the clusters down on a disk by simple dip chemistry … and thus replace present expensive top-down methods that are more environmentally harmful

6. Metal Organic Framework and Coordination polymers have wide applications such as separation, catalysis, and potential fuel-gas storage. Numerous metal organic frameworks have been synthesised and extensively studied during the last twenty years due to their fundamental interest as well as their technological applications. In recent years, this research activity was also devoted to the synthesis and studies of these hybrid materials at the nano level regime because of their unique physical properties and owing to the need for control over the size, shape and organization for their future incorporation into devices. Here we demonstrate the growth of nano dimensional MOF-5 and Ni-CHDC on various substrate. Substrate Catalyzed Nanoparticle Growth of Metal Organic Frameworks Prashant Jain @, Harold W. Kroto @, and Anthony K. Cheetham # @ Dept. of Chemistry & Biochemistry, Florida State University, USA # Materials Research Laboratory, University of California, Santa Barbara, USA Overview Growth of MOF-5 in the channels of Porous Anodized Alumina Membrane Zinc Nitrate and Terephthalic Acid Solution in DMF 125 0 C 3 Hours PAA Membrane PAA Membrane Filled With Reaction Mixture SEM Image of a Cross-section after the reaction SEM Images of MOF-5 crystallites grown in the PAA Channels Particle size can be controlled by varying the membrane diameter. In the PAA membrane with the pore diameter of 200 nm, most of the particles have approximate dimensions of 70nm X 35nm which suggest that physical restriction caused by the pore diameter plays a significant role. These PAA channels decorated with nanosized coordination polymers could be used for various application like gas purification and catalysis. It also leads to the possibility of growing other inorganic materials inside the channels electrochemically decorated with these hybrid materials. Cellular Assembly of Nickel-1,4 Cyclohexanedicarboxylate on a Silicon Wafer Nickel-1,4 cyclehexanedicarboxylate on Multi Walled Carbon Nano Tubes Ni-CHDC, with the layered structure, was grown on/around the MWCNTs. Further characterization is in progress. Above cellular structures were grown in-situ. Wafer was placed inside a hydrothermal reactor and was heated to 165 0 C.
