标题 :Polymers of intrinsic microporosity (pims) containing locked spirobisindane structures and methods of synthesis of pims polymers
发明人：JIN JIANYONG; ZHANG JIAN
权利人:AUCKLAND UNISERVICES LTD
摘要:A method of increasing the rigidity of PIM homo- or co-polymers including repeating units containing at least one biscatechol monomer having a fused spiro-bisindane (SBI) ring system of Formula (I), the SBI ring system including a bicyclic spiro-carbon: (I) wherein each R1 can be the same or different, each R2 can be the same or different and wherein R1 and/or R2 are selected from any one or more of H; straight or branched, saturated or unsaturated lower C1-C6 alkyl groups, wherein the lower alkyl groups can include aromatic or non-aromatic ring structures; R3OR4, R3O(Câ•?O)R4, R3C(â•?O)OR4, or R3OH, wherein each of R3 and R4 are the same or different and are selected from straight or branched, saturated or unsaturated lower C1-C6 alkyl groups; and R5 and R represent suitable linking monomers, wherein the linking monomers can be the same or different and are preferably selected from any one or more tetrahalo aromatic monomers; and wherein the method includes the step of introducing an intra-molecular lock between C1 and C2 of the biscatechol monomer of Formul (I).

标 题 :Process for the preparation of cyanotetrachlorobenzenes
发明人：MILNER DAVID J
权利人:ICI PLC
摘要:Cyanotetrachlorobenzenes, especially ortho- and para- dicyanotetrachlorobenzenes, are prepared by reacting in a liquid medium at 20 DEG -100 DEG C. a corresponding nitrotetrachlorobenzene with, in solution, an inorganic cyanide. Preferably the liquid medium is a two-phase water/water-immiscible organic solvent system, e.g. water/chloroform, a phase transfer catalyst is present and the inorganic cyanide is an alkali metal or alkaline earth metal cyanide. The compounds are useful chemical intermediates in the synthesis of, for instance, pesticidal compounds.

摘要:A composition comprising perfluoro-[2,2]-paracyclophane dimer compound is disclosed. The synthesis reaction of the paracyclophane dimer from 1,4-bis(chlorodifluoromethane)-2,3,5,6-tetrafluorobenzene involves heating in the presence of a metal catalyst and a solvent. A perfluorinated paraxylylene coating formed from the perfluorinated paracyclophane dimer is also disclosed.

摘要:Cross-linked polymer nanoparticles were designed and synthesized with cyclodextrins as the starting monomer. These nanoparticles display exemplary adsorption properties in terms of capacity and selectivity, which comes from the synthetic design. The nanoparticles are also highly robust for various practical adsorption applications. The new synthetic method of these nanoparticle materials involves the reaction of cyclodextrin monomers through an emulsion polymerization approach. The size of the nanoparticles can be tuned easily.
