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.

Ruthenium-catalyzed knoevenagel condensation: A new route toward cyano-substituted poly(p-phenylenevinylene)s
Liao, Jian,Wang, Qing
, p. 7061 - 7063 (2007/10/03)
The ruthenium-catalyzed Knoevenagel reaction was developed for the preparation of cyano-substituted conjugated polymers. The polymerization was quenched by pouring the reaction mixture into methanol. The structures of polymers were confirmed by spectroscopic studies and elemental analysis. The results show that Knoevenagel polycondensation mediated by transition metal complexes enjoys the advantages of neutral and mild reaction conditions.

High-molecular-weight, soluble and thermostable alkoxy-substituted arylene-ethynylene/arylene-vinylene conjugated polymers, 18 and 14, have been successfully synthesized through the Horner-Wadsworth-Emmons olefination of luminophoric dialdehydes 7 and 9 and bisphosphonate 12 in very good yields. They were characterized through 1H NMR, 13C NMR, IR, and elemental analysis. The investigation of their photophysical and electrochemical properties has been carried out. Although almost identical absorption and emission spectra were obtained in dilute chloroform solution for all polymers 13, the full width at half-maximum (fwhm) value of the emission curves depends on the length of the attached side chains. The presence of anthracenylene units in 14 leads to a red shift of its absorption and emission spectra relative to 13. Strong self-reabsorption after excitation in solution was observed for this polymer. The solid-state photophysical properties of 13 and 14 (photoconductivity, absorption and emission spectra, fluorescence quantum yield, Stokes shift, and fwhm) greatly depend on the nature (linear or branched), length, and location of the grafted alkoxy side groups. Photoconductivity is easily detected in polymers having octadecyloxy chains (13aa, 13ab, 14). Long linear (octadecyl, i.e., 13aa) or short branched (2-ethylhexyl, i.e., 13cc) side chains at position R2 (phenylene-vinylene segment) are necessary to obtain sharp and well-resolved emission spectra accompanied by high fluorescence quantum yields. The quasi-donor (phenylene-vinylene segment)-acceptor (arylene-ethynylene segment) nature of these polymers could explain the great discrepancy between the electrochemical band gap energy, Egec ≈ 1.60 eV, as obtained from the onset values of the redox potentials in cyclic voltammetry and in differential pulse polarography measurements, and the optical band gap energy, Egopt ≈ 2.30 eV, from the absorption spectra.
