专利号:US-2024399352-A1 优先权日:2023-06-03 标题:Second generation catalysts for reversible formic acid dehydrogenation 发明人:DO VAN; CHEREPAKHIN VALERIY; KELBER JACOB; WILLIAMS TRAVIS JESSE 权利人:UNIV SOUTHERN CALIFORNIA 摘要:The synthesis, structure, and reactivity of a family of iridium-based molecular cluster complexes, including neutron and X-ray single-crystal diffraction measurements, are provided. It is found that one complex, which includes an Ir3H6(μ3—H) trinuclear core, exhibits reactivity for reversible CO2 hydrogenation via hydride transfer. This reactivity is unlike previous reports of one known Ir3H6(μ3—H) complex, which is inert.
专利号:US-6376655-B1 优先权日:1995-06-02 标题:Physically functional materials 发明人:BERG ROLF HENRIK; HVILSTED SOEREN; RAMANUJAM P S 权利人:RISO NAT LAB 摘要:The invention relates to novel monodisperse or polydisperse compounds, in general named DNO (diamino acid Nα-substituted oligopeptides), preferably low molecular weight polypeptides, e.g., based on ornithine, lysine, diaminobutyric acid, diaminopropionic acid, aminoethylglycine or other amino acids or peptides having azobenzenes or other physicially functional groups, e.g., photoresponsive groups, as side chains. These compounds may be synthesized using solid phase peptide synthesis techniques. Materials, e.g., thin films, comprising such compounds may be used for optical storage of information (holographic data storage), nonlinear optics (NLO), as photoconductors, photonic band-gap materials, electrically conducting materials, electroluminescent materials, piezo-electric materials, pyroelectric materials, magnetic materials, ferromagnetic materials, ferroelectric materials, photorefractive materials, or materials in which light-induced conformational changes can be produced. Optical anisotropy may reversibly be generated with polarized laser light whereby a hologram is formed. First order diffraction efficiencies of up to around 80% have been obtained.
