Y. Kunugi et al., LIGHT-EMITTING-DIODES BASED ON LINEAR AND STARBURST ELECTRO-OLIGOMERIZED THIENYLTRIPHENYLAMINES, Synthetic metals, 89(3), 1997, pp. 227-229
4,4'-Dithienyl-4 ''-bromotriphenylamine or 4,4',4''-trithienyltripheny
lamine was oxidized on indium-tin oxide (ITO) electrodes providing lin
ear and starburst oligomers by thiophene coupling reactions. These oli
gomer layers were coated with aluminum and the resulting sandwiches we
re used as light-emitting diodes (LEDs). The photoemission and electro
emission were near 500 nm, with a luminance of about 35 cd m(-2)at 8 V
and 100 mA cm(-2). (C) 1997 Elsevier Science S.A.
