It was anticipated that fluorescein would be appropriate as such an acceptor,
because it has two conformations (lactone form and quinoid form) with distinctly
different absorption properties. Fluorescein in quinoid form has strong absorption
at ...

It is anticipated that the P+ can, in turn, be trapped near a quinoid group, leading
to a formation of P+Q, whose electronic transitions are at -1.4 eV and 3.0 eV. The
negative polaron, in contrast, is not expected to be trapped by ring torsion ...
