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 Usage And Synthesis

Description

2,3,6,7‐tetrahydro‐1,1,7,7,‐tetramethyl‐1H,5H,11H‐10(2‐benzothiazolyl)quinolizine‐[9,9a,1gh]coumarin (C545T) can be doped in Fluorescent white organic light‐emitting diodes (WOLEDs) with single‐emitting layer (EML) and double‐EML structures. The intermediation of C545T has high energy transfer ability.[1]

Chemical Properties

Vermeil powder

Definition

ChEBI: C545T is a member of 7-aminocoumarins and a member of benzothiazoles. It has a role as a fluorochrome.
