Abstract
Dendronized hyperbranched polymer (DHP) is a new kind of polymer, which combines the advantages of dendrimers and hyperbranched polymers. In this work, two dendronized hyperbranched polymers, DHPG0 and DHPG1, were successfully prepared through the simple “A3+B2” type Sonogashira coupling reaction. The nonlinear optical (NLO) effects of DHPG0 and DHPG1, characterized by the d 33 values, were 183 and 220 pm V–1 respectively, higher than those of their analogues of dendronized polymers and dendrimers, thanks to the special topological structure. Also, the obtained polymers displayed excellent solubility, good processability, and high thermal stability.
