Abstract

So far, second-order nonlinear optical (NLO) hyperbranched polymers have been widely reported; however, introduction of highly polarizable NLO chromophores into them remains a challenge. In this work, we have successfully prepared a tetracyanobutadienyl (TCBD)-based AB2-type hyperbranched polymer HP3 by integrating double click-type postfunctionalization reactions including Cu(I)-catalyzed Huisgen's 1,3-dipolar cycloaddition and alkyne-TCNE [2 + 2] cycloaddition. The NLO property of HP3 was carefully studied based on the second-harmonic generation (SHG) measurement, showing a SHG coefficient of 55.6 pm V−1 and good alignment stability with a depoling temperature of 125 °C.
