Sh. Lee et al., Highly soluble fluorenyl-substituted poly(1,4-phenylenevinylene) for bright and efficient blue-green light-emitting diode, CHEM LETT, (10), 2000, pp. 1184-1185
Poly[2-(9',9'-dihexyIfluorenyl)-1,4-phenylenevinylene] (DHF-PPV), which con
tains 9,9-dihexylfluorene as a pendant group, was synthesized by the modifi
ed Gilch polymerization of the corresponding bischloromethyl-substituted be
nzene monomer. Light emitting device fabricated with DHF-PPV showed high el
ectroluminescence efficiency with low turn-on voltage.
