合成并表征了三种芳香族二亚胺配体和相应的均配型铜( I )和铜( II )配合物。铜 ( II ) 衍生物由辅助氯配体稳定。螯合配体的性质严重影响配合物的光物理和电化学性质。用甲氧基取代侧基甲基影响配合物的配位几何,导致不同配位模式(即氮和氧结合)之间的分子内动态平衡,由变温证明1H-NMR 测量。作为概念证明,最有前途的配合物被用作半透明染料敏化太阳能电池中的氧化还原介质。一旦在设备中实施,配体的性质就起着至关重要的作用:甲氧基取代的衍生物在与叔丁基吡啶严重的配体交换时出现,导致出乎意料的高开路电压。
A series of methoxylated imidazo[1,5-a]pyridines is presented and their optical and electrochemical properties investigated and interpreted on the basis of density functional theory calculations. The photophysical properties are discussed in relation to the chemical structure. The key role of the 1,3 substitutions on the imidazo[1,5-a]pyridine nucleus on rotational barriers and on frontier molecular
提出了一系列甲氧基化的咪唑并[1,5- a ]吡啶,并根据密度泛函理论计算对它们的光学和电化学性质进行了研究和解释。讨论了与化学结构有关的光物理性质。讨论了咪唑并[1,5- a ]吡啶核在旋转势垒和前沿分子轨道上的1,3取代的关键作用,涉及实验性增色效应,光发射量子产率和电化学性质。根据咪唑并[1,5- a ]吡啶核上引入的甲氧基取代基的位置,我们能够调整斯托克斯位移并将发射量子产率从22%提高到50%。
