797057-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 797057-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,7,0,5 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 797057-71:
(8*7)+(7*9)+(6*7)+(5*0)+(4*5)+(3*7)+(2*7)+(1*1)=217
217 % 10 = 7
So 797057-71-7 is a valid CAS Registry Number.

Paragraph 0066; 0077; 0078, (2018/07/30)

A benzhydryl radical based on the stability of the organic light-emitting material at room temperature and using the material preparation of the organic electroluminescent device, which belongs to the field of organic light-emitting technology. The present invention in the preparation of the organic light-emitting material, the center of the common characteristic is the carbon free radical, is composed of two C - C covalent bond and a C - N to form a covalent bond. Stability is the light-emitting free radical material in the application of the key nature, connected to the electronic group conducive to stable free radical, in this invention through the nitrogen-containing heterocyclic carbazole, indole, dimethyl acridine and the like in the electronic group to the nitrogen atom is connected directly to the benzyl group, to obtain a stable benzhydryl radical, its stability and PTM, compared with the TTM is greatly improved, and has a room temperature fluorescent. The preparation of the material of the organic electroluminescent device using double thread condition exciton light-emitting, can avoid the traditional organic electroluminescent device in the use of the triplet state exciton, the maximum external quantum efficiency of the device is 0.66%.

Separation of electrical and optical energy gaps for constructing bipolar organic wide bandgap materials

Hu, Dehua,Shen, Fangzhong,Liu, He,Lu, Ping,Lv, Ying,Liu, Dandan,Ma, Yuguang

supporting information; experimental part, p. 3015 - 3017 (2012/04/04)

An electrical and optical energy gaps separation strategy is put forward for the design of organic wide bandgap semiconductors. This new principle could achieve optimization of wide bandgap (both high singlet and triplet energies) and favorable carrier injection energy levels simultaneously.
