142289-08-5 Usage
Description
4,4'-Bis(2,2-diphenylvinyl)-1,1'-biphenyl, also known as DPVBi, is a wide band gap small molecule semiconducting material characterized by its light yellow powder form. It is prominently utilized in the field of organic light-emitting diodes (OLEDs) as a blue host-emitting material.
Uses
Used in OLED Industry:
4,4'-Bis(2,2-diphenylvinyl)-1,1'-biphenyl is used as a blue host-emitting material for enhancing the performance of OLEDs. Its application in this industry is due to its ability to effectively manipulate the Schottky energy barrier between the ITO (indium tin oxide) and the emitting layer. This manipulation significantly improves the hole-injection, current, and luminance efficiencies of OLEDs, as well as their overall stability.
Classification
Hole-injection materials, Hole-transporting materials, Blue light-emitting materials, Host materials, Organic light-emitting diodes (OLEDs), Organic electronics.
Check Digit Verification of cas no
The CAS Registry Mumber 142289-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142289-08:
(8*1)+(7*4)+(6*2)+(5*2)+(4*8)+(3*9)+(2*0)+(1*8)=125
125 % 10 = 5
So 142289-08-5 is a valid CAS Registry Number.
