Method for preparing polyphenyl polyacid monomers

The invention relates to a preparation method for preparing polyphenyl polyacid monomers. The method comprises the steps that polymethyl polyphenyl is reacted with an oxidizing agent in an inert solvent under the catalysis of metal salt in the presence or absence of a ligand or in the presence or absence of an additive A as a co-catalyst or in the presence or absence of an additive B as a co-catalyst, and then the polyphenyl polyacid monomers are obtained. The method is relatively mild in condition, simple in operation, small in pollution and low in economic cost. The polyphenyl polyacid monomers can be used for synthesizing metal-organic frameworks (MOF) or self-assembled materials. (The chemical formulas are shown in the description.).

POROUS COORDINATION POLYMER AND APPLICATION THEREFOR

An object of the present invention is to provide a novel porous coordination polymer having superhydrophobicity. The present invention relates to a porous coordination polymer comprising: a divalent or trivalent metal ion; andan organic ligand represented by the following formula (1) : wherein X1, X2, and X3 are the same or different, and each represent CO2?, CS2?, PO32?, PO42?, AsO32?, AsO42?, SO3?, SO4?, SeO3?, SeO4?, TeO3?, or TeO4?; and R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and R12 are the same or different, and each represent hydrogen or C1-20 alkyl; the metal ion and the organic ligand being alternately linked by a coordinate bond.

Novel C3-symmetrical triphenylbenzene-based organogelators with different linkers between phenyl ring and alkyl chain

A new family of 1,3,5-triphenylbenzene-based organogelators with approximately identical side chain length have been synthesized and fully characterized. The molecular aggregation can be promoted by hydrogen-bonding and van der Waals interaction. The magnitudes of hydrogen bonding interactions between the linkers on the triphenylbenzene cores are qualitatively in the order of -CONHNHCO-, -NHCONH->-NHCO->-CONH->-NHCSNH-, consequently resulting in different gelation behaviors. The sol-gel transitions of gels 3 and 4 in toluene are thermodynamically reversible, while the formations of gels 2 and 5 in dioxane are kinetically controlled. The urea-based gel 2 can selectively recognize F- ion.

Influence of remote intramolecular hydrogen bonds on the thermodynamics of molecular recognition of cis-1,3,5-cyclohexanetricarboxylic acid

Variable temperature binding studies and isothermal titration microcalorimetry were used to probe the thermodynamics of molecular recognition of cis-1,3,5-cyclohexanetricarboxylic acid by tripodal hosts. Remote intramolecular hydrogen bonds, used to restr

Pentamacrocyclic Tris Crown Hosts. - Selective Binding of Cationic, Anionic, and Neutral Guest Compounds

The tris-crown host compounds 1-4 were synthesized for the first time.The X-ray structures of 2 and the 1:3 complex of 1 and KSCN were determined.Whereas in the free crown 2 a less well preorganized molecular cavity is encountered, in the complex of 1 wit

New Trigonal Lattice Hosts: Stoicheiometric Crystal Inclusions of Laterally Trisubstituted Benzenes - X-Ray Crystal Structure of 1,3,5-Tris-(4-carboxyphenyl)benzene*Dimethylformamide

New host molecules with a central 1,3,5-trisubstituted benzene ring and rigidly attached lateral arms composed of aryl or arylethynyl and extra fuctional groups are reported.They are shown to give more than thirty clathrates with a wide variety of organic solvents comprising alicyclic, aromatic, heterocyclic, dipolar aprotic, and protic molecules.Inclusion selectivities and stoicheiometries of the different clathrates are discussed.The crystal structure of (2a)*dimethylformamide (DMF) (1:3) inclusion compound has been determined from single-crystal X-ray diffraction.The crystals show R3 symmetry.There are six host and eighteen guest molecules in the hexagonal unit cell with a=b=23.160(9) and c=11.812(3) Angstroem.The final linear R is 0.082 for 1518 unique reflections.The host molecule adopts a propeller conformation with perfect three-fold symmetry and acts as a donor in hydrogen bonds to three DMF molecules.In the crystal structure the host-guest units are arranged stack-wise.
