The present invention discloses a diverse arylimidazole quaternary ammonium salt, a preparation method and an application thereof. The diverse arylimidazole quaternary ammonium salt is a compound represented by a formula (L-n'). The diverse arylimidazole quaternary ammonium salt has the following beneficial effects that: the diverse arylimidazole quaternary ammonium salt can be prepared through the one-pot method and is not prepared in a glove box, the raw material (aliphatic or aromatic imine) is subjected to the reaction, the yield is 78-94%, and the target product with high optical purity dr of more than 98:2 is obtained. According to the present invention, operations can be simplified, the yield can be increased, importantly an application range of the compound is expanded, and wide versatility is provided.
