Synthesis and characterization of oligo(9,9-dihexyl-2,7-fluorene ethynylene)s: for application as blue light-emitting diode.
[reaction: see text] Highly soluble and strongly blue fluorescent oligo(9,9-dihexyl-2,7-fluorene ethynylene)s (OFEs) were synthesized by a Pd/Cu-catalyzed Sonogashira coupling reaction. An organic light-emitting diode using pentamer 15 as the emitting material was successfully fabricated and emitted a bright blue light.
