“…At present, this type of hyperbranched polymers have been intensively explored in many research fields, such as organic light‐emitting devices, liquid crystal devices, two‐photon absorption materials, supermolecular assembly, drug release, chemsensors, nanoscale catalysis, and so on,36–40 because of the efforts of scientists. Based on the unique properties of hyperbranched polymers, from 2006, our group have been prepared a series of new hyperbranched polymers as nonlinear optical (NLO) polymeric materials (one kind of material with the promise of performance and cost improvements related to telecommunications, computing, embedded network sensing, THz wave generation and detection, and many other applications) 41–47. The three‐dimensional (3D) spatial separation of the chromophore moieties in the hyperbranched polymers endows the polymers with favorable site isolation effect, which could minimize the strong intermolecular electrostatic interactions among chromophore moieties with high dipole moment, thus enhance the macroscopic optical nonlinearities of polymers, according to our previous work and the literatures 41–51…”
