Alty, Isaac G.; Abelt, Christopher J. published the artcile< Stereoelectronics of the Hydrogen-Bond-Induced Fluorescence Quenching of 3-Aminofluorenones with Alcohols>, Product Details of C7H4BrNO4, the main research area is stereoelectronics hydrogen bond induced fluorescence quenching aminofluorenone alc.
Two derivatives of 3-amino-9-fluorenone (1) bearing one (2) and two Me (3) groups flanking the carbonyl group are prepared Comparison of their photophys. properties show that all suffer efficient radiationless deactivation in the presence of alcs. Preferential solvation studies with mono alcs. reveal that a single H-bonding interaction quenches the excited states of 1 and 2, but not that of 3. In contrast, a single mol. of ethylene glycol quenches all three. These results are interpreted in a quenching mechanism similar to one proposed by Inoue et al., but where an out-of-plane H-bond with the carbonyl group gives rise to an emissive species, while an in-plane H-bond results in quenching.
