Sh. Lee et al., Synthesis and characterization of oligo(9,9-dihexyl-2,7-fluorene ethynylene)s: For application as blue light-emitting diode, ORG LETT, 3(13), 2001, pp. 2005-2007
Highly soluble and strongly blue fluorescent oligo(9,9-dihexyl-2,7-fluorene
ethynylene)s (OFEs) were synthesized by a Pd/Cu-catalyzed Sonogashira coup
ling reaction. An organic light-emitting diode using pentamer 15 as the emi
tting material was successfully fabricated and emitted a bright blue light.
