Abstract: The UV and FL spectra of the title compounds were reported and substituent effects of them were discussed in this work. Fairly good correlations between λ_(max)~(uv) and Δσ(σ_p-σ_m), λ_(max)~(FL) and σ_p~+(or σ_m~+), stokes shift values and Δσ were established respectively.It showed that the electron effects of the substituents played a main role Spectra sensitivity toward N(CH_3)_2 and OH substituted compounds were also studied.

Key words: Pyrido[1,2-a]Indolium Salts, Spectral property, Substituent effect
