โœฆ Synopsis

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.

Equilibrium measurements at several temperatures between 293 K and 308 K have been performed on the tannase catalyzed reaction: 3,4,5-trihydroxybenzoic acid propyl ester(sln) + H2O(sln) = 3,4,5-trihydroxybenzoic acid(sln) + propan-1-ol(sln), where sln = aqueous phosphate buffer, aqueous acetate buff
