Controlling the Fluorescence Performance of AIE Polymers by Controlling the Polymer Microstructure

zu Verbundenen Objekten

Abstract: Aggregation‐induced emission (AIE) polymers with expected emission wavelength/color and fluorescence efficiency are valuable in applications. However, most AIE polymers exhibit irregular emission wavelength/color changes compared to the original AIE monomers. Here, we report the synthesis of AIE polymers with unchanged emission wavelength by ring‐opening (co) polymerizations of 4‐(triphenylethenyl) phenoxymethyloxirane (TPEO) and other epoxides or phthalic anhydride. The chemical structures/physical properties of all (co) polymers were characterized by NMR, SEC, MALDI‐TOF, and DSC. The co‐polyether microstructures were revealed by calculating the reactivity ratios and visualized by Monte Carlo simulation. The photoluminescence quantum yields of all the (co) polymers were determined in the solid state. We systematically correlated the fluorescence performance with molecular weights, crystallinity, monomer compositions, glass transition temperatures, side lengths, and flexibility/rigidity.
