Long-lived Charge-Transfer States in 9-Aryl-Acridinium Ions; A Critical Reinvestigation
In the recent literature a simple 9-aryl-acridinium ion was claimed to undergo an intramolecular, photoinduced charge shift to produce an extremely long-lived and very high energy charge-transfer state. The possible consequences of this observation are discussed and the tenability of the claims made...

| description | In the recent literature a simple 9-aryl-acridinium ion was claimed to undergo an intramolecular,
photoinduced charge shift to produce an extremely long-lived and very high energy charge-transfer state. The
possible consequences of this observation are discussed and the tenability of the claims made is investigated
via time resolved spectroscopy of a closely related system with spectroscopic characteristics allowing more
solid identification of the actual photophysical events taking place. From the results obtained it appears
likely that the long-lived species observed earlier in solution cannot be charge transfer in nature but must
instead be identified as the lowest triplet state of the acridinium chromophore. |
