Check Digit Verification of cas no

The CAS Registry Mumber 1450933-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,9,3 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1450933-18:
152 % 10 = 2
So 1450933-18-2 is a valid CAS Registry Number.

Spirofluorene and nitrogen-containing hetercyclic organic electroluminescent material and organic luminescent device thereof


Paragraph 0069; 0070; 0072, (2018/09/11)

The invention provides a spirofluorene and nitrogen-containing hetercyclic organic electroluminescent material and an organic luminescent device thereof and belongs to the technical field of organic photoelectric materials. The spirofluorene and nitrogen-containing hetercyclic organic electroluminescent material structurally contains a spirofluorene structure which is a blue-light structure with excellent property, not only has higher triplet energy level and wider energy gap, but also is higher in vitrifying conversion temperature and difficult in crystallization; by connection of groups suchas phenoxazine and phenothiazine and the like in molecules, the cavity transmission capability of the blue-light main body structure is added, so that the transportation of current carriers is balanced. Compared with the prior art, the spirofluorene and nitrogen-containing hetercyclic organic electroluminescent material is applied to the organic luminescent device, is especially used as a blue luminescent material in a luminescent layer and has relatively-higher luminescent efficiency.



Paragraph 0238; 0239; 0240, (2016/12/01)

The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.

Synthesis method of 1-bromo-9,9'-spirodifluorene


Paragraph 0015, (2017/03/28)

The invention discloses a synthesis method of 1-bromo-9,9'-spirodifluorene, belonging to the field of organic chemical synthesis. The method comprises the following steps: in an inert gas protective atmosphere, preparing a Grignard reagent in a methyl tetrahydrofuran solvent by using 1,3-dibromobenzene as an initial raw material, continuing reacting with ortho-halogen iodobenzene and magnesium powder under the catalytic action of zinc bromide, carrying out reaction with fluorenone, carrying out hydrolysis, and carrying out intramolecular closed loop synthesis under the catalytic action of boron trifluoride to obtain the 1-bromo-9,9'-spirodifluorene. The synthesis method has the advantages of simple process and cheap and accessible raw material, obviously lowers the production cost of the product, and widens applicability of fluorene derivatives as an intermediate in organic photoelectric material design and synthesis.
