C545T, for highly-efficient OLED devices as a green-emitting dopant
High-purity and available online for priority dispatch, 10-(2-Benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H,11H-(1)benzopyropyrano(6,7-8-I,j)quinolizin-11-one, Coumarin 545T, Sublimed ≥99.0%, CAS No. 155306-71-1
C545T (also known as Coumarin 545T) is a family member of Coumarins.
Coumarins have been studied extensively for their applications in electronic and photonic devices. They possess high emission yield, excellent photo-stability, variable absorption range, and good solubility. As such, coumarins are widely used as fluorescence probes, charge-transfer materials, and dyes for OLEDs, OPV and laser dye applications.
C545T is commonly used for highly-efficient OLED devices as a green-emitting dopant and electron transport host material. With four methyl groups and enhanced solubility, Coumarin 545T is also used in laser dyes with increased laser conversion efficiencies at higher concentrations.
* Sublimation is a technique used to obtain ultra pure-grade chemicals, see sublimed materials.
