• Detailed Description:

  The cyanocoumarin derivative 9-cyano-10-(2- benzothiazolyl)-1,1,7,7-tetramethyl-2,3,6,7-tetrahydro--benzo pyrano[6,7,8- ]quinolizin-11-one (RC545T), and its use in organic light-emitting diodes (OLEDs). Because RC545T exhibits (i) redshifted fluorescence and (ii) a narrower full width at half-maximum (fwhm; 48 nm) relative to the corresponding signal for 4-(dicyanomethylene)- 2-tert-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)--pyran (DCJTB;;), which is currently one of the most efficient red dopant materials, we could fabricate red OLEDs exhibiting improved colorpurity. A device incorporating RC545T as a dopant and rubrene as an assistant dopant in the configuration indium–tin oxide(ITO)/-bis(1-naphthyl)--diphenyl--biphenyl--diamine/tris(8-hydroxyquinoline)aluminumrubrene:RC545Texhibited a maximum luminance ofat, with near-saturated CIE coordinates of (0.64, 0.35), significantly better red color purity than that of the device featuringDCJTB as the dopant material [CIE coordinates: (0.63, 0.37)], thereby rendering RC545T a good red-emitting dopant for OLEDapplications.HanShang Chemical Scientific Limited(mrHou,tel: 8.6.0.2.1.5.0.1.8.9.2.9.8 )is specialized in4-(4-chlorophenyl)dibenzothiophene/custom synthesis/organic intermediates.Are you looking for the best4-(4-chlorophenyl)dibenzothiophene/custom synthesis/organic intermediatesin Shanghai?HanShang Chemical Scientific Limited is the best4-(4-chlorophenyl)dibenzothiophene/custom synthesis/organic intermediatesmanufacturer In shanghai.&&&
