  • Patent number: 10604539
    Abstract: Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

  • Patent number: 10344005
    Abstract: Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

  • Patent number: 8986855
    Abstract: Derivatives of benzo[h]naphtho[1,2-f]quinoline and organic light emitting devices (OLEDs) including them are disclosed. The subject compounds impart high efficiency, low driving voltage, high luminance and long lifespan to the OLEDs. The subject compounds may be used as light emitting materials, as electron transporting materials, or as electron injecting materials. Because the subject compounds have high glass transition temperatures or high melting points, OLEDs including them exhibit high durability in storage or operation. Suitable substituents may be selected from deuterium, alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, aryloxy, arylthio, aryl, aryl- or heteroaryl-substituted amino, heteroaryl, condensed polycyclic, halogen, cyano, nitro, hydroxyl and carboxyl groups.
