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.

As a fused-ring conjugated unit, triphenodioxazine, has been applied in two series of thiophene-free conjugated polymers for polymer solar cells. The polymers were synthesized through a multi-step synthetic route, and the substituents had a great effect on the reactivity of the reactants. Relationships among the polymer structures as well as thermal, optical, and electrochemical properties were investigated in detail by experimental data analysis and theoretical simulation. The polymers possess highly planar backbones, broad Vis/NIR absorption bands, suitable frontier molecular orbital energies, and low band gaps ranging from 1.3 to 1.8 eV. The power conversion efficiencies of their photovoltaic devices are about 1 %. Introducing longer alkyl side chains into a polymer can bring about a better film-forming ability and improve the photovoltaic performance.

Anthanthrone and its derivatives are large polycyclic aromatic compounds (PACs) that pose a number of challenges for incorporation into the structure of soluble conjugated polymers. For the first time, this group of PACs was employed as the building blocks for the synthesis of copolymers (P1-P5) based on poly[(arylene ethynylene)-alt-(arylene vinylene)]s backbone (-Ph-C=C-Anth-C=C-Ph-CH - CH-Ph-CH - CH-)n. During the synthesis of P1-P5, different alkyloxy side chains were incorporated in order to tune the properties of the polymers. Of the copolymer series only P1 (containing anthanthrone and branched 2-ethylhexyloxy side chains on phenylenes), P2 and P3 (for which the anthanthrones containing carbonyl groups were converted to anthanthrene containing alkyloxy substituents) were soluble. The photophysical, electrochemical, electroluminescent and photovoltaic properties of P1-P3 are reported, compared and discussed with respect to the effects of side chains.
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.

A series of fullerene-terminated oligo(phenylene ethynylene)s (OPEs) (1a-d and 2) have been synthesized and further characterized by cyclic voltammetry (CV) and UV-vis spectroscopy. The key step in the syntheses is an effective one-pot reaction that allow
The CA.M lattice revisited. Gel formation from a linear bis-isocyanuric acid and 2-amino-4,6-bis-(4-tert-butylphenylamino)-1,3,5-triazine

Five bis(isocyanuric) acid dimers have been prepared and characterised. The introduction of flexible alkyl chains was necessary to aid solubility. On mixing with N,N-bis(4-tert-butyphenyl)melamine in THF followed by slow evaporation, a viscous gel can form which is interpreted as evidence for the assembly of an infinite 2-D hydrogen bonded network.

The synthesis and metal ion responsive properties of two 2,2'-bipyridyl-phenylene-vinylene-based polymers is reported. These polymers are designed to be partially conjugated in their metal-free state and fully conjugated when exposed to metal ions so that

, p. 635 - 638 (2007/10/02)
Intermolecular Friedel-Crafts acylation of various substituted alkyl- or alkoxybenzenes with oxalyl chloride using carbon disulfide as solvent gave rise to the benzils 1a-k.Subsequent intramolecular oxidative coupling with either thallium(III) oxide/trifluoroacetic acid or vanadium(V) oxyfluoride/boron trifluoride diethyl etherate resulted in the corresponding phenanthrene-9,10-diones 2a-d.It has been shown that oxygen functionalities at the 3,3',4, and 4'positions are necessary for coupling to occur.These substituted benzils and phenanthrene-9,10-diones constitute precursors for ligands in the field of discotic metallomesogens or polymeric mesogens.
