概要	Functional dyes are one of the most attractive materials because of their potential use in microenvironment probes, bioapplications, and optoelectronic devices. The modification of chemical structures of the functional dyes due to external stimuli such as heat and photo-irradiation affects the absorption and emission behavior of the dyes. Among them, solvatochromic molecules are attracting great interest because they are used as molecular sensors and indicators. Herein, we investigated chemiluminescence using betaine 30 and dansyl acid ethyl ester (DNSE) as solvatochromic molecules. We demonstrated chemiluminescent reactions using a mixture of betaine 30 or DNSE as the functional dye and bis(2,4,6-trichlorophenyl) oxalate as a precursor to introduce a high-energy moiety under chemiluminescence conditions in several solvents. Although betaine 30 did not exhibit fluorescence except with toluene, DNSE showed different emission colors depending on the solvent polarity, which indicated that chemiluminescence depends on the environment.
