dependence of the intramolecular hydrogenabstraction reaction of n-alkyl anthraquinone-2-carboxylates (AQ-n, n=2–20) has been studied by steady-state photolysis, phosphorescence, laser flash photolysis, and two-step laser induced fluorescence spectroscopies. All the results indicate that the excited triplet of the anthraquinone chromophore abstracts a hydrogen atom from its methylene side chain, whose rate

The photoinduced charge transfer between tetracyano-anthraquino-dimethane (TCAQ) derivatives and poly[2-methoxy-5-(3,7-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO−PPV) has been studied by photoinduced absorption (PIA) spectroscopy in the VIS and IR spectral region and by light induced electron spin resonance (LESR). Studies on three different TCAQ derivatives with different side chain substitutions
通过光诱导吸收 (PIA) 研究了四氰基蒽醌二甲烷 (TCAQ) 衍生物与聚[2-甲氧基-5-(3,7-二甲基辛氧基)-1,4-亚苯基亚乙烯基] (MDMO-PPV) 之间的光诱导电荷转移。 ) 在 VIS 和 IR 光谱区域中的光谱和光诱导电子自旋共振 (LESR)。报道了对具有不同侧链取代的三种不同 TCAQ 衍生物的研究。其中,已合成了一种与富勒烯相连的 TCAQ 超分子,用作串联电子受体。在可见光/近红外范围内的光致吸收显示出一个大约 1.8 eV 的宽平台,然后是 1.35 和 1.24 eV 的两个峰,对于与 MDMO-PPV 复合的所有三个受体,还有一个低于 0.5 eV 的额外宽特征。所有 PIA 特征都具有幂律激发强度依赖性,其指数接近 0.5,正如双分子动力学所预期的那样。LESR 研究表明,g 因子为 2.0028,宽度(峰到峰)为 3.5 G,源自 TCAQ ...
