CAT gene -- fluorescent substrates?

Hello fellow netters,
I have a question for those who work with the chloramphenicol
acetyltransferase gene.  I was wondering if a substrate for CAT exists

   (i)  is fluorescent and
   (ii) has a reaction product that is retained within a live cell.

Such a substrate night work in the same way that FDG
(fluorescein-D-galactopyranoside) works for live staining of LacZ-positive

Thanks in advance,
