Zum Fluoreszenzverhalten des 8,8′‐Bis(acridizinium‐yls)

Fluorescence Behaviour of the Isomeric Bis(acridizinium‐yl)Dications The fluorescence behaviour of the isomeric bis(acridizinium‐yl)dications is characterized by anomalies of the spectra. At room temperature the emission spectra of the 7,7′‐ and the 8,8′‐isomer show the typical characteristics of a TICT fluorescence band, they are strong red shifted and structureless. The emission wavelength shows the typical dependence on the solvent. At 77 K the expected spectra are obtained. The room temperature spectrum of the 9,9′‐isomer is the result of a plain emitting molecular state. The emission wavelength is only slightly red shifted. The solvent influences the molecular dynamics in the excited state. The differences in the deactivation behaviour of the isomers are caused by different energies of the Frank Condon singlet states.
