Description
TSPO1, also known as diphenyl[4-(triphenylsilyl)phenyl]phosphine oxide, is an electron transfer layer (ETL) or hole blocking layer (HBL) in organic electronic devices, such as organic light-emitting diodes (OLEDs) and delayed fluorescent devices. It has a unique structure consisting of a triphenylsilane connecting to a triphenyl phosphine oxide group. TSPO1 exhibits a large permanent dipole moment due to the polar phosphine oxide group and its asymmetric structure.
Uses
Used in Organic Electronic Devices:
TSPO1 is used as a phosphine oxide-based blocking and host material for the formation of a blocking layer in organic electronic devices. This enhances the performance of devices like OLEDs and delayed fluorescent devices by utilizing its triplet energy excitons.
Used in OLED Industry:
TSPO1 is used as an electron transfer layer (ETL) or hole blocking layer (HBL) in the OLED industry. Its role is to improve the efficiency and performance of OLED devices by acting as a barrier to unwanted charge carriers, thus preventing energy loss and increasing the overall device lifetime.
Used in Advanced Material Research:
TSPO1's unique structure and properties make it a promising candidate for research in advanced materials, particularly in the development of novel organic electronic devices and systems. Its large permanent dipole moment and asymmetric structure offer opportunities for exploring new applications and improving device performance.
Check Digit Verification of cas no
The CAS Registry Mumber 1286708-86-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,0 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1286708-86:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*0)+(3*8)+(2*8)+(1*6)=198
198 % 10 = 8
So 1286708-86-8 is a valid CAS Registry Number.

External quantum efficiency above 20% in deep blue phosphorescent organic light-emitting diodes
Jeon, Soon Ok,Jang, Sang Eok,Son, Hyo Suk,Lee, Jun Yeob
, p. 1436 - 1441 (2012/02/13)
Highly efficient deep blue phosphorescent organic light-emitting diodes (PHOLEDs) with external quantum efficiency above 20% are developed using a bipolar-type high-triplet-energy host material and a high-triplet-energy exciton blocking material. Maximum quantum efficiency of 25.1% and low roll-off (still 23.1% at 1000 cd m-2) are achieved in these deep blue PHOLEDs. Copyright
