摘　　要：Substituted 10H-pyrido [1, 2-a] indolium salts can be used as sensitizing dyes and fluorescent whiteners. Their utilities have close relation with their spectral properties and the study on this relation has great significance in the synthesizing designation of the compounds. The ultraviolet absorption spectra and fluorescence emission spectra of nine known series compounds have been investigated. It has been found that the conjugated substituents introduced in position 8 make the maximum absorption band λ_max and maximum
