The control experiment involved using ABMDMA with a maximum absorbance of 1 in water. The solutions were irradiated in an open quartz cuvette by continuous stirring. The absorbance measurements followed by irradiation were taken every 5 min. A 520 nm green LED lamp was used as the light source.The absorbance spectrum of ABMDMA in water showed that the absorbance stayed constant for 30 minutes (Figure 2). Figure 3 shows the absorbance changes of 9‚10-anthracenediyl bis(methylene)dimalonic acid
