英文摘要：

Pyrylium salts are a type of heterocyclic compounds with unique chemical reactivity and photophysical properties. They show great potential applications in the many fields such as organic synthesis, biosensor and organic optoelectronic materials. Based on our recent research results, in this review, the developments in the synthesis of both α-non-active pyrylium salts and α-active pyrylium salts are summarized, and the applications of some typical pyrylium salts in the organic synthesis, photosensitizers, ion liquid and fluorescent sensor are exemplified.
