Description

This lecture introduces Metal-Organic Frameworks (MOFs), emphasizing their unique properties such as nano-sized channels in 1-, 2-, and 3-dimensions, high surface areas, and chemically tunable characteristics. It covers various MOFs like HKUST-1, MOF-1002, and VOF-1001, discussing their structures and applications. The lecture also delves into ligands used in MOFs, including first-generation linkers and common ligands like BIPY and HBDC. Furthermore, it explores specific functionalities imparted by ligands like porphyrin linkers. The presentation continues with discussions on SBUs, bipyridine-based MOFs, and structures like MOF-74 and UIO-66. It concludes with insights into zeolitic imidazolate frameworks (ZIFs) and their varying topologies.

Metal–organic framework

Metal–organic frameworks (MOFs) are a class of compounds consisting of metal clusters (also known as SBUs) coordinated to organic ligands to form one-, two-, or three-dimensional structures. The organic ligands included are sometimes referred to as "struts" or "linkers", one example being 1,4-benzenedicarboxylic acid (BDC). More formally, a metal–organic framework is an organic-inorganic porous extended structure. An extended structure is a structure whose sub-units occur in a constant ratio and are arranged in a repeating pattern.

Covalent organic framework

Covalent organic frameworks (COFs) are a class of materials that form two- or three-dimensional structures through reactions between organic precursors resulting in strong, covalent bonds to afford porous, stable, and crystalline materials. COFs emerged as a field from the overarching domain of organic materials as researchers optimized both synthetic control and precursor selection.

Ligand

In coordination chemistry, a ligand is an ion or molecule with a functional group that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. The nature of metal–ligand bonding can range from covalent to ionic. Furthermore, the metal–ligand bond order can range from one to three. Ligands are viewed as Lewis bases, although rare cases are known to involve Lewis acidic "ligands".

Porphyrin

Porphyrins (ˈpɔːrfərɪn ) are a group of heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges (=CH−). In vertebrates, an essential member of the porphyrin group is heme, which is a component of hemoproteins, whose functions include carrying oxygen in the bloodstream. In plants, an essential porphyrin derivative is chlorophyll, which is involved in light-harvesting and electron transfer in photosynthesis.
