简单介绍


ossila材料C545T  的详细介绍

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.
