  exist in both cis-enol and keto forms in solution, and their relative contents were determined by 1H NMR measurements. In contrast, for the β-triketone, only enol form was observed in a solution. A strong fluorescence quenching was observed for unsaturated diketones as compared with the saturated ones. These β-diketones displayed reversible photoinduced ketonization as revealed by UV–vis spectroscopy. The
