摘要：
Fluorescent hyperbranched polymers (FHBPs), which combine the versatile fluorescent property with unique characteristics of hyperbranched architecture, are desirable candidates for stimulus responsive materials. This review demonstrates the structure and environment-dependent emission behaviors of a series of FHBPs. AEE active FHBPs showing opposite performance to ACQ effect are used to sensitively detect explosives and a superamplification effect is found. Specially designed FHBPs can complex with metal ions, leading to fluorescence turn-off due to complex quenching effect. The protonation of amino-containing FHBPs exhibits pH-dependent fluorescence responses to solution acidity. Some FHBPs containing responsive moieties are photo- and thermo-sensitive, and show potential applications as smart materials.
