  New Phenyl-Substituted PPV Derivatives for Polymer Light-emitting Diodes−Synthesis, Characterization and Structure−Property Relationship Study

  摘要：

  Three new PPV derivatives with dialkoxyphenyl substituents, BEH2P-PPV, BEH3P-PPV, and BEH4P-PPV have been synthesized. The polymers were characterized by FT-IR, H-1 NMR, and elemental analysis. The polymers possess excellent solubility, high molecular weights, high photoluminescence efficiencies and good thermal stability. The influence of substitution pattern on the formation of structural defects has been investigated by measuring the signal due to tolane-bisbenzyl moieties (TBB) in the proton NMR spectra. BEH2P-PPV with a steric phenyl group at the ortho-position on the side phenyl ring shows the lowest amount of TBB, which indicates suitable steric hindrance can be applied to suppress the formation of irregular head-to-head and tail-to-tail linkage in the polymer chains. In addition, the polarity of solvents used for the Gilch polymerization will also affect the amount of irregular structure in the polymers. Polar solvents such as THF will result in polymers with low TBB content. Energy level measurement from cyclic voltammetry revealed that the influences of the substitution pattern on the HOMOs and LUMOs are different. The three polymers possess similar HOMO energy levels while the LUMO of BEH4P-PPV is much higher than that of the other two polymers. Polymer light-emitting diodes fabricated from BEH2P-PPV, BEH3P-PPV, and BEH4P-PPV with the configuration of ITO/PEDOT/polymer/Ba/Al, emitted bright blue-green to green light with the maximum peaks at 496, 488, and 525 nm, respectively. The turn-on electric field and maximum external quantum efficiencies of the diodes are 0.30, 0.50, and 0.42 MV/cm and 0.37%, 0.66%, and 0.25% respectively. The quantum efficiency is mainly determined by the electron injection from the cathode. With the highest luminance, lowest turn-on electric field, and good quantum efficiency as well as negligible structural defects, BEH2P-PPV is the most promising material among the three polymers for polymer light-emitting diodes.

  支链和直链烷氧基链包裹的推挽卟啉用于开发高效的染料敏化太阳能电池

  摘要：

  已经设计，合成了四种包含吩噻嗪衍生的供体和乙炔基苯甲酸受体的烷氧基包裹的推挽卟啉染料，并将其用作制造高效染料敏化太阳能电池（DSSC）的敏化剂。支链或线性烷氧基链被引入到内消旋的邻位。苯基部分可抑制染料聚集和电荷重组。在不存在和存在另外的吸电子苯并噻二唑单元的情况下，研究了烷氧基链的作用。在前一种情况下，支链和直链烷氧基链的光伏效率几乎相同，约为8.3％，而在后一种情况下，平面苯并噻二唑单元会引起严重的染料聚集和电荷重组，从而导致效率降低6.46％即使获得了更宽的吸收率，对于直链和支链分别为7.50％和7.50％。具有支链的染料获得的相对较高的效率可能与抑制染料聚集和电荷重组的更好效果有关。此外，采用了共吸附法 具有支链和苯并噻二唑单元的染料的最高效率为9.62％。这些结果构成了一种通过开发共吸附剂和含有额外的苯并噻二唑受体和支链烷氧基链的卟啉染料来开发高效DSSC的新方法。
