20120070904 | NANOPOROUS CARBOHYDRATE FRAMEWORKS AND THE SEQUESTRATION AND DETECTION OF MOLECULES USING THE SAME - Disclosed are cyclodextrin-based metal organic frameworks comprising a metal cation and cyclodextrin or a cyclodextrin derivative. These metal organic frameworks are permanently porous and capable of molecule storage. | 03-22-2012 |
20120319058 | SUPRAMOLECULAR NETWORKS WITH ELECTRON TRANSFER IN TWO DIMENSIONS - Organic charge-transfer (CT) co-crystals in a crossed stack system are disclosed. The co-crystals exhibit bidirectional charge transfer interactions where one donor molecule shares electrons with two different acceptors, one acceptor face-to-face and the other edge-to-face. The assembly and charge transfer interaction results in a pleochroic material whereby the optical absorption continuously changes depending on the polarization angle of incident light. | 12-20-2012 |
20130069010 | MODULAR SUPRAMOLECULAR APPROACH FOR CO-CRYSTALLIZATION OF DONORS AND ACCEPTORS INTO ORDERED NETWORKS - Organic charge-transfer (CT) co-crystals in a mixed stack system are disclosed, wherein a donor molecule (D) and an acceptor molecule (A) occupy alternating positions (DADADA) along the CT axis. A platform is provided which amplifies the molecular recognition of donors and acceptors and produces co-crystals at ambient conditions, wherein the platform comprises (i) a molecular design of the first constituent (α-complement), (ii) a molecular design of the second compound (β-complement), and (iii) a solvent system that promotes co-crystallization. | 03-21-2013 |
20130122297 | MOLECULAR GAUGE BLOCKS FOR BUILDING ON THE NANOSCALE - Disclosed herein is a way to produce a series of discrete sized slender, rigid oligoparaxylene molecules ranging from 1-5 nm in length. Molecules, based on 1-7, 9-11 paraxylene rings, have been synthesized as part of a homologous series of oligoparaxylenes (OPXs) with a view to providing a molecular tool box for the construction of nano architectures—such as spheres, cages, capsules, metal-organic frameworks (MOFs), metal-organic polyhedrons (MOPs) and covalent-organic frameworks (COFs), to name but a few—of well-defined sizes and shapes. Twisting between the planes of contiguous paraxylene rings is generated by the steric hindrance associated with the methyl groups and leads to the existence of soluble molecular gauge blocks without the need—at least in the case of the lower homologues—to introduce long aliphatic side chains onto the phenylene rings in the molecules. | 05-16-2013 |
20140179017 | TETRACATIONIC CYCLOPHANES AND THEIR USE IN THE SEQUESTRATION OF POLYAROMATIC HYDROCARBONS BY WAY OF COMPLEXATION - Novel tetracationic cyclophanes incorporating π-electron poor organic compounds into their ring structures, as well as methods of making the cyclophanes, are provided. The cyclophanes are able to form electron donor-acceptor complexes with a variety of polyaromatic hydrocarbons (PAHs) ranging in size, shape, and electron density. Also provided are methods of using the cyclophanes in the sequestration of PAHs in liquid or gaseous samples, the separation of PAHs from liquid or gaseous samples, the detection of PAHs in liquid samples, and the exfoliation of graphene via pseudopolyrotaxane formation. | 06-26-2014 |
20140311297 | COMPOUNDS AND METHODS TO ISOLATE GOLD - Methods for recovering gold from gold-bearing materials are provided. The methods rely upon on the self-assembly of KAuBr | 10-23-2014 |
20150191470 | CRYSTALLINE BIPYRIDINIUM RADICAL COMPLEXES AND USES THEREOF - Described herein are methods of generating 4,4′-bipyridinium radical cations (BIPY | 07-09-2015 |
20150322174 | Nanoporous Carbohydrate Frameworks and the Sequestration and Detection of Molecules Using the Same - Disclosed are cyclodextrin-based metal organic frameworks comprising a metal cation and cyclodextrin or a cyclodextrin derivative. These metal organic frameworks are permanently porous and capable of molecule storage. | 11-12-2015 |
