Abstract

In this paper, a facile synthetic route was designed to prepare two new hyperbranched polymers HP1 and HP2 useful as second-order nonlinear optical (NLO) materials through a one-pot “A2 + B4” approach via a simple Suzuki coupling reaction. Thanks to the effect of the isolation chromophores to the main chromophore and the three-dimensional spatial isolation effect of the hyperbranched structure, these hyperbranched polymers demonstrated high second-harmonic generation coefficients (up to 73.6 pm V−1) and good optical transparency (with the maximum absorption as 466 nm in film).
