In this article, according to the concept of suitable isolation group,'' six new AB(2)-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. With the different end-capping groups, these hyperbranched polymers, P1-P6, exhibited different solubility and processability; also, their nonlinear optical properties were modified accordingly, realizing the adjustment of the properties of hyperbranched polymers through the structural design.
