DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 22, 76 The optical and electroluminescent properties of 3,4,6-triphenyl-a-pyrone (a-pyrone), a new blue fluoresce dye, are investigated using films prepd. by wet and dry process and org. light-emitting diodes (OLEDs) fabricated with an a-pyrone-emitting layer. The optical properties of a-pyrone are found to be affected by its crystallinity. In the fabrication of OLEDs, wet processing (spin coating) is shown to be more suitable for prepn. of the a-pyrone layer than dry processing (thermal evapn.). The best device performance is obtained for a device prepd. using poly (n-vinylcarbazole) as the dye host, and a bathocuproine/tris-(8-hydroxyquinoline)aluminum bilayer as a hole-blocking and carrier-injection layer. The max. luminance of this device is 3000 cd/m2 at a c.d. of 0.2 A/cm2, with a current efficiency of 1.8 cd/A at 0.02 A/cm2.Except for chemicals metioned above, 155090-83-8 and 50926-11-9 are also used. .

DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 36, 76 Single-walled carbon nanotube (SWNT) films on flexible PET (polyethyleneterephthalate) substrates are used as transparent, flexible anodes for org. light-emitting diodes (OLEDs). For polymer-based OLEDs having the structure: SWNT/PEDOT-PSS:MeOH/TFB (poly(9,9-dioctylfluorene-co-N-(4-butylphenyl)diphenylamine)) + TPD-Si2 (4,4'-bis[(p-trichlorosilylpropylphenyl)phenylamino]biphenyl) /BT (poly(9,9-dioctylfluorene-co-benzothiadiazole))/CsF/Al, a max. light output of 3500 cd/m2 and a current efficiency of 1.6 cd/A have been achieved. The device operational lifetime is comparable to that of devices with Sn-doped In2O3 (ITO)/PET anodes. 7440-44-0 and 155090-83-8 are just another two chemicals used in this study. The advantages of this novel type of anode over conventional ITO are discussed. .
