4,4',4''-Tris(carbazol-9-yl)-triphenylamine, also known as tris(4-carbazoyl-9-ylphenyl)amine (TCTA), is an electron-rich organic compound characterized by its light yellow solid appearance. It features three carbazole units as pendants and a triarylamine at the core, which contributes to its unique electronic properties. Usage: Used in Light-Emitting Materials: 4,4',4''-Tris(carbazol-9-yl)-triphenylamine is used as a key component in the preparation of light-emitting materials for organic electroluminescent devices. Its electron-rich nature, low electron mobility, and high lying LUMO energy level (2.4 eV) make it an ideal candidate for this application. Used in Light-Emitting Diodes (LEDs): In the electronics industry, 4,4',4''-Tris(carbazol-9-yl)-triphenylamine is used as a hole-transport and hole-injection material in light-emitting diodes. Its ability to efficiently transport holes and inject them into the emissive layer contributes to the improved performance of these devices. Used in Perovskite Solar Cells: 4,4',4''-Tris(carbazol-9-yl)-triphenylamine is also utilized in the development of perovskite solar cells. Its electron-rich properties and low electron mobility make it a suitable material for enhancing the efficiency of these solar cells. Used as Exciton/Electron Blocking Layer Materials: Due to its high lying LUMO energy level, 4,4',4''-Tris(carbazol-9-yl)-triphenylamine is used as an exciton/electron blocking layer material. This application is particularly relevant in the design of multilayered organic light-emitting diodes, where it helps to confine excitons and electrons within the emissive layer, thus improving device performance. Used in Phosphorescent Host Materials: In the field of green, red, and white phosphorescent organic light-emitting diodes (PhOLEDs), 4,4',4''-Tris(carbazol-9-yl)-triphenylamine is used as a popular phosphorescent host material. Its large band gap (3.4 eV) allows for efficient energy transfer to phosphorescent emitters, resulting in enhanced device performance and longer operational lifetimes.
The CAS Registry Mumber 139092-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,9 and 2 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 139092-78: (8*1)+(7*3)+(6*9)+(5*0)+(4*9)+(3*2)+(2*7)+(1*8)=147 147 % 10 = 7 So 139092-78-7 is a valid CAS Registry Number.
