The quantum yield (F D ) of singlet oxygen (O 2 ( 1 D g ) production by 9H-fluoren-9-one (FLU) is very sensitive to the nature of the solvent (0.02 in a highly polar and protic solvent, such as MeOH, to 1.0 in apolar solvents). This high sensitivity has been used for probing the interaction of FLU w
