Abstract: As spectral sensitizers, the indolyl-10H-pyrido[1,2-a]indolium perchlorates Ia~k were synthesized. The UV and FL spectra of Ia~k bave been studied. In UV spectra, good correlation between λmax1 and substituent constants Δσ+p+m+) was obtained. In FL spectra, the intramolecular energy transfer was observed. The spectral sensitization for polyvinylcarbazole (PVCz) of Ia~k has been tested. It was found that the sensitivity of PVCz/TNF was increased witb addition of I (R=NMe2).

Key words: pyridoindolium salt, substituent effect, intramolecular energy transfer, spectral sensitizer
