Phloroglucinol 4, hydroquinone 5 and naphthalene-2,6-diol 6 react with the monomer 2, activated either by 1,3-dicyclohexylcarbodiimide (DCC) or as its acid.chloride 3. Hydrogenolysis of the benzyl protecting groups, followed by repetition of these procedures leads, divergently, to three series of analytically pure aryl polyester dendrimers in high yields. The de Gennes limit appears to lie between generations three and four with the three-branched initiator core 4 and between generations four and five with the two-branched cores 5 and 6.
氯代葡萄糖醇 4、对苯二酚 5 和萘-2,6-二醇 6 与单体 2 反应,单体 2 通过 1,3-二环己基碳二亚胺 (DCC) 或其酸性氯化物 3 活化。苄基保护基团氢解,然后重复这些步骤,以不同的方式产生了三个系列的高产率分析纯芳基聚酯树枝状聚合物。三支化引发剂核心 4 的德-吉尼斯极限似乎位于第三代和第四代之间,而双支化核心 5 和 6 的德-吉尼斯极限似乎位于第四代和第五代之间。
