“suitable isolation group,” six new AB2‐type polytriazoles containing azo‐chromophore moieties, derived from the same hyperbranched polymer intermediate, were successfully prepared through click reaction under copper(I) catalysis by modifying the synthetic route, in which different isolation groups in different size were introduced to the periphery of the hyperbranched polymers as end‐capping moieties.

在本文中,根据“合适的隔离基团”的概念,通过铜(I)催化下的点击反应,通过改性,成功地从相同的超支化聚合物中间体中衍生出了六种新的含偶氮发色基团的新型AB 2型聚三唑。合成路线,其中将不同大小的不同隔离基团作为封端基团引入到超支化聚合物的外围。具有不同的封端基团,这些超支化聚合物P1 - P6,表现出不同的溶解度和可加工性;同时,对它们的非线性光学性质进行了相应的修饰,通过结构设计实现了对超支化聚合物性质的调节。©2011 Wiley Periodicals,Inc. J Polym Sci A部分:Polym Chem,2011年
