Abstract
Electroluminescent diodes utilizing poly(3-alkylthiophene) (PAT) conta ining fluorescent dyes have been fabricated and their unique enhanceme nt of emission characteristics have been studied. Remarkable Enhanceme nt of the electroluminescence efficiency has been observed for diodes with PAT doped with oxadiazole derivative phenylyl)-5-(4-tert-butylphe nyl)-1,3,4-oxadinzole; PBD) and perylene derivative (N,N' - Bis(2,5 di - tert - butylphenyl) - 3,4,9,10 - perylenedicarboximide; BPPC). The mechanism of emission enhancement by doping of PBD into PAT has been d iscussed with different alkyl side-chain lengths. (C) 1997 by John Wil ey & Sons, Ltd.
