Simple Synthesis, Outstanding Thermal Stability, and Tunable Light-Emitting and Optical-Limiting Properties of Functional Hyperbranched Polyarylenes

The synthesis, thermal stability and optical properties of functional hyperbranched polyarylenes were reported. The molecular structure of the polymers was determined by nuclear magnetic resonance (NMR) spectroscopy. The spectra showed that the hyperbranched polymers possessed a random molecular composition, an irregular stereostructure and a rigid core architecture. The optical limiting and tunable light emitting properties of the polymers make them suitable to be used for high-tech applications.
