TL;DR: In this paper, the π,π * absorption spectra of fluorenone and 9,10-phenanthrenequinone were examined and it was found that there is an exact similarity between these two spectra up to near 250 nm.

Abstract: A series of polyethers consisting of a modified terfluorenediol connected with a nonconjugated spacer were synthesized and characterized in respect to their thermal, electrochemical, optical and morphological properties. The polymers were further investigated as thin deposits with the use of the FT‐IR technique after thermal (200°C for 30 min) and photo‐oxidation treatment. After thermal treatment no generation of the carbonyl stretching mode of the fluorenone moiety is observed, while after photo‐oxidation in various times (between 5 to 30 min) the appearance of the fluorenone unit is well established. Furthermore, the length of the flexible spacer used influenced the optical properties of the polyethers after thermal treatment. In particular, odd ones showed more intensely the low energy emission band at 520 nm after the thermal treatment in contrast to even ones.

TL;DR: The potential of the analogs of 2 as biochemical research tools has been demonstrated by the findings that 7 and 8 can replace 2 in apolipoprotein A-I-induced cellular efflux of 2 and that fluorescence is easily visible at the surface of smooth muscle cells equilibrated with 8.
