4569-45-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4569-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,6 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4569-45:
(6*4)+(5*5)+(4*6)+(3*9)+(2*4)+(1*5)=113
113 % 10 = 3
So 4569-45-3 is a valid CAS Registry Number.

Metal-selective coordination and enhanced fluorescence of a self-assembling ligand scaffold

Bogie, Paul M.,Lyon, Yana,Holloway, Lauren R.,Julian, Ryan R.,Hooley, Richard J.

, p. 936 - 945 (2017)

A fluorescent hydroxyiminonicotinonitile (HINT) coordinating group can be incorporated into self-assembling ligand scaffolds, and shows metal-selective assembly and enhanced fluorescence. The assembly process is dependent on ligand coordination angle, and coordination only occurs for oxophilic first row transition metal ions, with affinity enhanced by the supramolecular assembly process. The ligands are weakly emissive, and show strong enhancement in fluorescence upon Zn2+ coordination, whereas Co2+ or Fe2+ cause complete quenching.

Fluorene-containing diamine monomer, polyimide film and preparation method and application thereof

-

, (2021/05/12)

The invention relates to the technical field of organic photoelectric polymers, and particularly relates to a fluorene-containing diamine monomer, a polyimide film and a preparation method and application thereof. The fluorene-containing diamine monomer provided by the invention has a structure as shown in a formula I defined in the description. The fluorene-containing diamine monomer provided by the invention is polymerized with a dianhydride monomer, so that the heat resistance of a polyimide film can be greatly improved, and the thermal expansion coefficient of the film can be reduced.

New synthesis method of 9,9-dimethyl fluorene

-

Paragraph 0015-0039, (2019/02/04)

The invention belongs to the technical field of synthesis of a chemical display material, relates to a new synthesis process of an OLED material intermediate and particularly relates to a new synthesis method of 9,9-dimethyl fluorene. According to the method, the 9,9-dimethyl fluorene is prepared by performing reaction on dimethyl carbonate serving as a methylating reagent and fluorene in an organic solvent system within a certain temperature range and under the condition of alkaline substances. The dimethyl carbonate serves as the methylating reagent, so that the reaction process is stabilized and the economic property is greatly improved; meanwhile, due to use of the dimethyl carbonate, use of low-boiling-point highly toxic products such as methyl iodide and methyl bromide is avoided andenvironmental friendliness is realized; furthermore, the generated wastewater is single in component and convenient to treat.
