Covalent Organic Frameworks As An Organic Scaffold For Heterogeneous Catalysis Including C-H Activation, Harsh Vardhan
Covalent Organic Frameworks As An Organic Scaffold For Heterogeneous Catalysis Including C-H Activation, Harsh Vardhan
USF Tampa Graduate Theses and Dissertations
Linking small organic molecules into an extended solid usually afford disordered amorphous polymers. The instigation of order into such a material is of profound interest to induce inherent fine control of the overall structure. Covalent organic frameworks (COFs) are new class of porous crystalline material prepared by connecting organic building blocks via strong covalent bonds. The judicious choice of organic monomers can give rise to highly ordered and predictable frameworks with high crystallinity, surface area, and thermal/chemical stability. The role of connecting linkages such as B─O, C─C, C─N extends the principle of fundamental molecular covalent chemistry to the formation of …

Research in metal-organic frameworks (MOFs) has risen greatly in recent decades Owing to their unequaled potential tunability and structural diversity. MOFs may be described as crystalline structures composed of metal cations or clusters of cations, commonly referred to as secondary building units (SBUs), and custom-designed organic ligands. The variety of structural motifs, ligands, and SBUs that may be incorporated promote the attainment of essentially countless potential MOFs and application in numerous areas of interest, such as gas adsorption, catalysis, gas separation, and sensing. Further functionalization of MOF materials by means of post-synthetic modification(PSM)33–37 of metal clusters or organic ligands, constructing …
Organic-Inorganic Hybrid Materials Based On Oxyanion Linkers For Selective Adsorption Of Polarizable Gases, Mona Hanafy Mohamed
Organic-Inorganic Hybrid Materials Based On Oxyanion Linkers For Selective Adsorption Of Polarizable Gases, Mona Hanafy Mohamed
USF Tampa Graduate Theses and Dissertations
The separation of industrially important gases into pure supplies that can be used for many practical applications is based mainly on energy intensive methods such as the cryogenic distillation which is costly and energy intensive. Therefore other routes have been introduced to industrial separation of gases such as the selective adsorption using porous solid materials. Zeolites and activated carbon are the most widely used recyclable energy-efficient porous solid materials for industrial gas separations, however the low uptake and selectivity hurdles their commercialization in some separation applications. Metal organic frameworks (MOFs) have been extensively studied as solid porous materials in term …

USF Tampa Graduate Theses and Dissertations
Metal-organic materials (MOMs) represent a unique class of porous materials that captured a great scientific interest in various fields such as chemical engineering, physics and materials science. They are typically assembled from metal ions or metal clusters connected by multifunctional organic ligands. They represent a wide range of families of materials that varied from 0D to 3D networks: the discrete (0D) structures exemplified by metal-organic polyhedra (MOPs), cubes and nanoballs while the polymeric 1D, 2D and 3D structures exemplified by coordination polymers (CPs). Indeed, the porous 3D structures include metal-organic frameworks (MOFs), porous coordination polymers (PCPs) and porous coordination networks …
