Abstract
An NLO hyperbranched polymer (HP1) derived from both “H”-type and star-type chromophores was synthesized successfully for the first time with high yield via one-pot “A2 + B3” Suzuki polymerization reaction. Isolation chromophore was also introduced to further improve its performance. Although under the test conditions, the films of HP1 could not be poled completely, it still demonstrated satisfactory macroscopic NLO effect with the second harmonic generation (SHG) coefficient d 33 value of 36 pm/V.
