Synthesis of poly (3,4,5-trihydroxybenzoate ester) dendrimers and their chemiluminescence

Gallic acid (GA) and gallic acid methyl ester (GM), polyphenol chemiluminescence (CL) compounds, produces light in the presence of alkali and hydrogen peroxide. We synthesized first-generation polyphenol dendrimers with GA units in the periphery and measured their CL for developing a polyphenol compound which has a strong CL intensity. The CL intensities of the poly (3,4,5-trihydroxybenzoate ester) dendrimers 4 and 8 in MeOH are approximately 400- and 600-fold stronger than that of GA, respectively.
