Check Digit Verification of cas no

The CAS Registry Mumber 1246308-85-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,3,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1246308-85:
(9*1)+(8*2)+(7*4)+(6*6)+(5*3)+(4*0)+(3*8)+(2*8)+(1*5)=149
149 % 10 = 9
So 1246308-85-9 is a valid CAS Registry Number.

Carbazolo-aromatic ring thermal activation delayed fluorescence material and organic electroluminescent device thereof

-

, (2020/10/04)

The invention discloses a carbazolo-aromatic ring thermal activation delayed fluorescence material and an organic electroluminescent device. The structural formula of the carbazolo-aromatic ring thermal activation delayed fluorescent material is shown in the specification. The carbazolo-aromatic ring thermal activation delayed fluorescent material provided by the invention takes a carbazolo-aromatic ring as a core; due to the large volume and rigidity, molecules have a steric hindrance effect, intramolecular distortion is realized, and electron clouds of the highest occupied orbit and the lowest empty orbit of the molecules can be relatively separated to obtain a quite small single triplet state energy level difference, so that light-emitting molecules with a thermal activation delayed fluorescence property are designed and prepared; the thermal performance, the light-emitting efficiency and the light color of the material can be adjusted, and the material can be used as a guest material, can also be used as a host material by utilizing the thermal activation delayed fluorescence property, and can be constructed through molecular design.

Dibenzothiophene dioxide-benzofuro carbazole based bipolar host material for yellow and red phosphorescent OLEDs

2-(12H-benzofuro[3,2-a]carbazol-12-yl)dibenzo[b,d]thiophene 5,5-dioxide (DBT-INFUR) is a bipolar host material for yellow and red phosphorescent OLEDs. DBT-INFUR was designed and synthesized between dibenzothiphene acceptor and benzofuro carbazole donor with a yield of 60percent. We constructed two different devices, namely a yellow and a red phosphorescent OLEDs, and we compared the device properties with reference 4,4′-Bis(N-carbazolyl)-1,1′-biphenyl (CBP). DBT-INFUR based yellow phosphorescent OLED device exhibited maximum current and external quantum efficiencies of 41.07 cd/A and 16.5percent, respectively and which is better than that of reference CBP based similar device (27.66 cd A, 10.15percent). DBT-INFUR based red phosphorescent OLED (12.44percent) revealed higher efficiencies when compared to the reference (7.64percent) device. The bipolar DBT-INFUR showed excellent host properties with yellow and red phosphorescent devices.
