Dication Ethers, 6. Spectroscopic Comparisons of 9,9'-Oxy-bis(acridinium)- and 9,9'-Thio-bis-(acridinium) Salts with Other 9-Substituted Acridinium Ions

9,9'-Oxy-bis(acridinium) salts 2a and 2b as well as the 9,9'-thio-bis(acridinium) salt 2c have been compared with other 9-substituted acridinium salts by 1H NMR, 13C NMR, and UV/VIS spectra.The data show that the bond state of the acridine rings in 2a-c is quite similar to that in 9-(pseudo)halide-substituted acridinium ions, i.e., the aromatic conjugation throughout the heterocyclic system is not disturbed. - Keywords: Bis(acridinium) Ethers, 9-Substituted Acridinium Ions, 13C NMR Spectra, UV Spectra, 1H NMR Spectra
