PPP ~a l c u l a t i o n s ~~~ the electron spectra of the acepleiadylenes (5a)-(5f)-alI strongly fluorescent-depend little on the nature of the substituents R'-R4. Not unexpectedly the UV spectrum of the non-fluorescent ( 5 9 ) is distinctly different.

in DMF hampered the measurement of its transient spectra, we examined the dynamics of the photoexcited states of 2 and 4 in DMF. The energy levels of the ion pairs were calculated to be 1.41 eV for Dp+-Hp--Im and 1.19 eV for Dp'-Hp-Im-. Analysis of the transient absorption spectra of 2 and 4 reveals
