摘　　要：取代10H-吡啶并[1,2-a]吲哚盐是一类较好的离子型染料和萤光增白剂,在纤维织物的染色以及照相化学中得到广泛应用,其性能与光谱特性密切相关。对于此类化合物的电子光谱,仅有文献就其紫外光谱作了研究。作者合成了12个题示新化合物,测定了紫外和萤光光谱。本文进一步研究取代基对题示化合物紫外和萤光光谱特性的影响,寻找化合物结构与性能之间的定量关系。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) andΔσ(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.
