Description
Bis(2-methyl-8-quinolinolato-N1,O8)-(1,1'-Biphenyl-4-olato)aluminum, also known as BAlq or BAlq3, is a compound that is widely utilized in the field of organic light-emitting diodes (OLEDs). It is characterized by its ability to emit blue light and act as a hole-blocking layer or a "barrier-softening" interfacial layer between the electron transporting and emissive layers. BAlq3 possesses a glass transition temperature of 99 °C and demonstrates photochemical stability.
Uses
Used in Organic Light-Emitting Diodes (OLEDs) Industry:
Bis(2-methyl-8-quinolinolato-N1,O8)-(1,1'-Biphenyl-4-olato)aluminum is used as a blue-emitting layer material for its ability to produce blue light in OLEDs. This property makes it a crucial component in the development of energy-efficient and high-quality display technologies.
Bis(2-methyl-8-quinolinolato-N1,O8)-(1,1'-Biphenyl-4-olato)aluminum is also used as a hole-blocking layer in OLEDs to prevent the recombination of electrons and holes, which can lead to a decrease in device efficiency and lifetime.
Furthermore, BAlq3 serves as a "barrier-softening" interfacial layer between the electron transporting and emissive layers, enhancing the overall performance and efficiency of the OLED device.
Used in Red Phosphorescent OLEDs (PHOLEDs) Industry:

Its application in this context helps improve the efficiency and lifetime of PHOLEDs, with some devices achieving high lifetimes of up to 160,000 hours at a luminance level of 100 cd/m2.
Classification
Electron transporting materials, Hole blocking materials, Light emitter layer materials, Phosphorescent host materials, Organic light-emitting diodes, Organic electronics, Sublimed materials.
Check Digit Verification of cas no
The CAS Registry Mumber 146162-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,1,6 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146162-54:
(8*1)+(7*4)+(6*6)+(5*1)+(4*6)+(3*2)+(2*5)+(1*4)=121
121 % 10 = 1
So 146162-54-1 is a valid CAS Registry Number.
