Porphyrinic phenoxynaphthacenequinones
Myles, Andrew J.,Branda, Neil R.
, p. 3785 - 3788 (2007/10/03)
The photophysical properties of porphyrinic phenoxynaphthacenequinones 1 and 2 were investigated to assess their potential use as gated photoinduced electron transfer systems. Although the photophysical properties of the porphyrin chromophores remain unal
