Joseph M. Falkowski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20180318815
    Abstract: A novel metal organic framework, EMM-33, is described having the structure of UiO-67 and comprising bisphosphonate linking ligands. EMM-33 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-33, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.

  • Patent number: 10118169
    Abstract: Metal-organic framework (MOFs) compositions based on chiral phosphine-, chiral oxazoline-, chiral pyridine-, and chiral diene-derived organic bridging ligands were synthesized and then post-synthetically metalated with metal precursors such as Ru and Rh complexes. The metal complexes could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the addition of arylboronic acids to ?,?-unsaturated ketones and alkimines, the hydrogenation of substituted alkene and carbonyl compounds, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

  • Publication number: 20180273390
    Abstract: A novel zeolitic imidazolate framework material comprises a partially saturated benzimidazole or a partially saturated substituted benzimidazole as a linking ligand, optionally together with unsaturated benzimidazole or an unsaturated substituted benzimidazole as a further linking ligand.

  • Publication number: 20180142066
    Abstract: Provided herein are compositions and methods for use of an organosilica material comprising a copolymer of at least one monomer of Formula [R1R2SiCH2]3 (I), wherein, R1 represents a C1-C4 alkoxy group; and R2 is a C1-C4 alkoxy group or a C1-C4 alkyl group; and at least one other monomer of Formula [(Z1O)xZ23-xSi—Z3—SZ4] (II), wherein, Z1 represents a hydrolysable functional group; Z2 represents a C1-C10 alkyl or aryl group; Z3 represents a C2-C11 cyclic or linear hydrocarbon; Z4 is either H or O3H; and x represents any one of integers 1, 2, and 3. The composition may be used as a support material to covalently attach transition metal cations, as a sorbent for olefin/paraffin separations, as a catalyst support for hydrogenation reactions, as a precursor for highly dispersed metal nanoparticles, or as a polar sorbent for crude feeds.
