| 英文摘要 | A series of ethynyl-linked pi-conjugated light-emitting molecules with good photolummescence properties were designed and synthesized through Pd/Cu-catalyzed Sonogashira coupling reaction. The main Structure comprised of different fluorophors (pyrene, carbazole, and fluorene), which were linked with triple bonds in order to be screened for high emission efficiency. Optical properties of these synthesized compounds (I-a-I-f) were examined in solutions, thin films and solid states, respectively. All of them showed relative high quantum yields both in solutions(phi(s):0.70-0.83)and in films(phi(f): 0.17-0.34). Light-emitting diode using I-c as an emissive layer was fabricated in the ITO/poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS)/I-c/2, 2 ', 2 ''-(1, 3, 5)-benzene-triyl)tris[1-phenyl-1H-benzimidazole] (TPBI)/A1 configuration. The maximum emission wavelength of the device was 496 nm. The maximum luminance and electroluminescence efficiency was 1000 cd/m(2) and 0.41%, respectively. (c) 2005 Elsevier B.V.
