Description
3,3'-[5'-[3-(3-Pyridinyl)phenyl][1,1':3',1''-terphenyl]-3,3''-diyl]bispyridine, also known as TmPyPB, is a compound with a low-lying HOMO, high triplet energy level, and electron-deficient pyridine groups. It is widely used as an electron-transport layer and hole-blocking layer material in organic electronic devices such as OLEDs, OPV, and perovskite solar cells.
Uses
Used in Organic Light Emitting Diodes (OLEDs):
3,3'-[5'-[3-(3-Pyridinyl)phenyl][1,1':3',1''-terphenyl]-3,3''-diyl]bispyridine is used as an electron-transport and hole/exciton-blocking material for highly efficient phosphorescent OLEDs application. Its high electron mobility (10^-4-10^-3 cm^2 V^-1 s^-1) and high triplet energy level (2.75 eV) contribute to the device's performance and efficiency.
Used in Organic Photovoltaics (OPV):
In the field of organic photovoltaics, 3,3'-[5'-[3-(3-Pyridinyl)phenyl][1,1':3',1''-terphenyl]-3,3''-diyl]bispyridine serves as an electron-transport layer, enhancing the charge separation and collection process, which in turn improves the overall efficiency of the solar cells.
Used in Perovskite Solar Cells:
3,3'-[5'-[3-(3-Pyridinyl)phenyl][1,1':3',1''-terphenyl]-3,3''-diyl]bispyridine is utilized as a hole-blocking layer in perovskite solar cells, preventing the recombination of charge carriers and thus improving the device's performance and stability.
Check Digit Verification of cas no
The CAS Registry Mumber 921205-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,2,0 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 921205-03:
(8*9)+(7*2)+(6*1)+(5*2)+(4*0)+(3*5)+(2*0)+(1*3)=120
120 % 10 = 0
So 921205-03-0 is a valid CAS Registry Number.
