Abstract: Dihydroxybenzoic acid,the starting material, is esterified with methanol to protect the carboxylic group,then react with benzoyl chloride to obtain methyl 3, 5-bisbenzoyloxybenzoate,3,5-Bisbenzoyloxybenzoic acid is obtained with high yield by removing the protecting group with AlCl3/NaI. Then this acid reacts with methyl 3, 5-dihydroxybenzoate to obtain the second generation dendron with methyl ester at the anchor point.The second genration acid is obtained by deprotecting with AlCl3/NaI.Aryl poly-ester dendrimer is obtained by the reaction of the acid with 4, 4' -biphenol.Their structures are established with IR and NMR spectra.
