Synthetic method of N-arylated viologen molecule containing aldehyde group

The invention discloses a synthesis method of an aldehyde group-containing N-arylated viologen molecule, which adopts a Nesmeyanov reaction, and the aldehyde group-containing N-arylated viologen molecule is prepared through a reaction of a pyridine compound and an aldehyde group-containing asymmetric iodonium molecule. The synthesis method provided by the invention is simple in process, easy to purify, high in yield and strong in universality. The prepared molecules have excellent electrochemical performance and electrochromic performance. The introduction of the aldehyde group further expands the modifiable space, provides infinite possibilities for constructing various functional materials containing viologen, and is expected to be applied to a plurality of fields such as electro/photochromism, energy storage, adsorption, supramolecular chemistry, catalysis, sensing and the like. 本发明公开了一种含醛基的N-芳基化紫精类分子的合成方法，该方法采用Nesmeyanov反应，通过吡啶类化合物和含醛基的不对称碘鎓分子反应制备含醛基的N-芳基化紫精类分子。本发明提供的合成方法工艺简单，易于纯化、收率高、通用性强。所制备的分子具有优异的电化学性
