and significantly reduces the hydrodynamic volume of the oligomers. The electronic properties (absorption and emission spectroscopy and cyclic voltammetry) give reasonable correlations with the chain length. With regard to the emission maxima, the effective conjugation length is already reached with the hexamer. Oligophenothiazines are highly fluorescent, with high fluorescence quantum yields, and are
从N-己基吩噻嗪开始,可以通过一系列的溴化,溴-锂交换/硼化和Suzuki偶联,轻松制备通用的溴化和硼化吩噻嗪构建试剂盒。随后的构建基的Suzuki芳基化以良好的产率提供了可溶的,单分散的和结构良好的低聚吩噻嗪。通过GPC(凝胶渗透色谱法)获得的最大峰分子量(Mp)与通过质谱法获得的低聚物系列的实际分子量显示出极好的相关性。对整个系列的QM / MM构象分析表明,明显的蝴蝶形吩噻嗪结构成倍增加,并显着降低了低聚物的流体动力学体积。电子性质(吸收和发射光谱和循环伏安法)与链长合理地相关。关于发射最大值,六聚体已经达到有效的共轭长度。寡吩噻嗪具有高荧光性,高荧光量子产率,并且同时具有高电活性和低氧化电位。
