Paragraph 0030-0036, (2020/08/18)
The invention provides a novel bipyridyl bidentate ligand and a preparation method thereof. The structural formula of the novel bipyridyl bidentate ligand is shown in the specification. The inventionfurther provides a ruthenium supramolecular self-assembly body of the ligand and a preparation method of the ruthenium supramolecular self-assembly body. The preparation method comprises the followingsteps: putting a prepared ruthenium receptor and a bipyridyl ligand into a container, adding a mixed solvent of methanol and dichloromethane in equal proportion, stirring for a period of time at roomtemperature, spin-drying the solution to a certain volume after the reaction is finished, slowly adding diethyl ether, and separating out solid powder, namely the ruthenium supramolecular self-assembly body containing the bipyridyl ligand. The self-assembly body is a novel ruthenium-containing self-assembly compound, and has a good inhibition effect on cancer tumor cell lines A549 and HepG-2.

Triple-stranded helicates were obtained by metal-templated multicomponent reactions of bispyridyloxime ligands with arylboronic acids. The helicates feature two hexa-coordinated MII ions (M=Fe, Zn, or Mn), which are embedded in a macrobicyclic ligand framework, and two arylboronate ester capping groups. The latter can be used to introduce functional groups such as pyridines, aldehydes, nitriles, and carboxylic acids in apical position. The functionalized helicates have the potential to be used as nanoscale building blocks for more complex assemblies, as evidenced by the synthesis of a 3 nm-sized trianglimine.

Three new coordination polymers have been synthesized based on three linear pyridine ligands with different side chains and one flexible V-shaped dicarboxylate co-ligand: {[Co(L1)0.5(sdb)]}n (1), {[Co(L2)0.5(sdb)]·1.5H2O}n (2) and {[Co(L3)0.5(sdb)]·2DMF}n (3) (L1 = E,E-2,5-dioctyloxy-1,4-bis-[2-pyridin-vinyl]-benzene; L2 = E,E-2,5-dibutoxy-1,4-bis-[2-pyridin-vinyl]-benzene; L3 = E,E-2,5-dimethoxy-1,4-bis-[2-pyridin-vinyl]-benzene; H2sdb = 4,4′-sulfonyldibenzoic acid). Complexes 1-3 are 4-connected sql nets with a point symbol of {44·62}. The interpenetration forms and porosity of frameworks have been well controlled by side chain prolongation. A larger steric hindrance for the pendant -OnOct and -OnBut groups leads to a larger repulsive force between the layers and effective construction of inclined polycatenations. A smaller steric hindrance for the pendant -Me group leads to the formation of a parallel stacked network. Therefore, compounds 1 and 2 feature 3D structures with inclined polycatenation (2D + 2D → 3D); compound 3 exhibits a non-interpenetrated 2D + 2D → 2D parallel stacked network. These complexes have been characterized by single crystal X-ray diffraction, infrared spectroscopy, thermogravimetry, elemental analysis, and powder X-ray diffraction measurements. In addition, the gas adsorption properties of the compounds have also been explored.

During our search for novel conjugated compounds, novel monomers and their polymers with selenophene and tellurophene group were synthesized and characterized. Conjugated poly(p-phenylenevinylenes)s (PPV) derivatives attracted a large attention due to their photolouminescence properties. The stereocontrolled synthesis of 1,4-bis(2-(heteroar-2-yl) ethenyl)benzenes and 1,4-bis(heteroar-2-yl)benzenes with tellurophene, selenophene, thiophene and furan-based monomers has been successfully performed. Eight of p-phenylene derivatives have been synthesized, electrochemically polymerized and characterized.
Aryl trihydroxyborate salts: Thermally unstable species with unusual gelation abilities
Moy, Cheryl L.,Kaliappan, Raja,McNeil, Anne J.
experimental part, p. 8501 - 8507 (2011/12/04)
A series of aryl trihydroxyborate salts were synthesized and found to form gels in benzene. The compounds were thermally unstable and readily underwent protodeboronation in solution and the solid state. Gelation could be induced without decomposition via sonication. Subsequent characterization studies revealed an unusual dependence of gel properties on alkyl chain length.

, p. 3285 - 3290 (2007/10/03)
Platinum(ii) complexes bearing various alkyne-pyrene, alkyne-4′-terpyridine and alkyne-dibutoxyphenylacetylide-terpyridine units were constructed in a step-by-step procedure based on copper-promoted cross-coupling reactions with preconstructed modules; formation of bis(ligand) complexes of Fe(ii) and Zn(ii) by binding of the pendent terpyridine units provided heterotrinuclear derivatives, all of which exhibit highly structured absorption features in solution and display a rich electrochemistry due to the presence of various redox active modules.

Kuhnert, Nikolai,Lopez-Periago, Ana,Rossignolo, Giulia M.
, p. 524 - 537 (2007/10/03)
The synthesis of series of D2h and C2v symmetric oxygenated aromatic dicarboxaldehydes, using dilithiation methodology, is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give oxygenated trianglimine macrocycles. Macrocycles derived from C2v symmetric dialdehydes give macrocycles with a stereogenic aromatic plane with complete diastereocontrol, as a mixture of retainers.
The preparations and some properties of mixed aryl-thienyl oligomers and polymers
Pelter, Andrew,Jenkins, Ieuan,Jones, D. Elfyn
, p. 10357 - 10400 (2007/10/03)
The syntheses by transition metal coupling reactions of a large number of oligomers constructed from benzene and thiophene rings are described. The first use of arylcadmium chlorides for such coupling reactions is reported. The routes chosen allow for rational variation in the modes of linkage, the substitution and the proportions of the two units. The benzene and thiophene rings are always joined in a known order and may bear a wide variety of regularly spaced functional groups. Additionally the shape of the oligomers may be varied at will. In all cases p-type doping with iodine or ferric chloride leads to large enhancements in conductivity.
