摘要： 以3,5-二羟基苯甲酸为起始原料,经甲醇酯化保护羧基,与苯甲酰氯反应,得到3,5-二苯甲酰氧基苯甲酸甲酯,用AlCl3/NaI去掉保护基甲基,以高收率得到3,5-二苯甲酰氧基苯甲酸,此酸与3,5-二羟基苯甲酸甲酯反应得到第二代酯端基树枝,再去掉保护基甲基,得到第二代羧酸树枝,将其与联苯二酚反应得到聚芳酯树状分子,其结构均由IR、1HNMR、EA等方法证实。

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.

Key words: Polyester, Dendrimer, Protect-deprotect
