  Alternating Aromatic and Transannular Chromophores with and without Linker:  Effect of Transannular π−π Interaction on the Optical Property of Dithiaparacyclophane-based Copolymers

  摘要：

  A series of bithiophene-cyclophane (PPP-type), acetylene-fluorene-acetylene-cyclophane (PPE-type), and ethylene-fluorene-ethylene-cyclophane (PPV-type) copolymers, namely, 4-6, was synthesized via a nickel-catalyzed reaction, a palladium-catalyzed Sonagashira reaction, and a Heck coupling, respectively. Unlike in the fluorene-cyclophane copolymer 3, the transannular pi-pi interaction of the cylophane unit in copolymer 4 resulted in a significant blue shift in its emission spectrum compared to a reference polymer, giving it an essentially blue emitting light. By introducing an acetylene or ethylene linker in going from 3 to 5 or 6, the effective conjugation in the polymer backbone due to higher rigidity in coplanarity decreased the effect of the transannular pi-pi interaction. While the PPV-type copolymer 6 still exhibited an appreciable red shift in both absorption and emission with respect to a reference polymer, negligible shifts were observed for copolymer 5.

  Design, Synthesis, and Electroluminescent Property of CN−Poly(dihexylfluorenevinylene) for LEDs

  摘要：

  A new green electrolumineseence polymer, CN-poly(dihexylfluorenevinylene) (CN-PDHFV), which denotes poly [(9,9-dihexyl-9H-fluorene-2,7-diyl)(1-cyanoethene-1,2-diyl)(9,9-dihexyl-9H-fluorene-2,7-diyl)(2-cyaoethene-1,2-diyl)], was synthesized by condensation polymerization utilizing the Knoevenagel reaction. The resulting polymer exhibits good solubility in common organic solvents such as chloroform, THF, and ODCB. The polymer is also easily cast on a glass plate to green film. The UV-vis spectrum of the polymer exhibits characteristically a broad absorption band at 440 nm. This polymer shows photoluminescence around lambda(max) = 535 nm (exciting wavelength 410 nm) and green electroluminescence around.. = 530 nm. The current-voltage-luminance (I-V-L) characteristics of the polymer show a turn-on voltage of 4.8 V and a brightness of 600 cd/m(2) at 5.8 V in the Al/polymer/PEDOT/ITO device. The highest efficiency was observed to be 0.85 1m/W at 5.6 V.
