Fluorescent supramolecular polymers are an important kind of smart material. In this work, a new fluorescent supramolecular hyperbranched polymer (FSHP) is constructed by orthogonal self-assembly: pillararene-based host-guest interaction and metal ion complexation interaction. The FSHP exhibits concentration-controllable fluorescence emissions. The photoluminescence spectra and light-emitting colors of FSHP can be effectively tuned by changing metal ion types or using mixed metal ions. The fluorescence quenching of FSHP solutions or FSHP-based films would occur when removing the metal ions from the backbone of FSHP. This study supplies a convenient approach toward the construction of structure-tunable fluorescent supramolecular materials with different colors.
荧光超分子聚合物是一种重要的智能材料。在这项工作中，通过正交自组装构建了一种新型的荧光超分子超支化聚合物（FSHP）：基于柱芳烃的主客体相互作用和金属离子配位相互作用。FSHP 表现出浓度可控的荧光发射。通过改变金属离子类型或使用混合金属离子，可以有效地调节 FSHP 的光致发光光谱和发光颜色。从 FSHP 的主链中除去金属离子时，FSHP 溶液或 FSHP 基膜的荧光猝灭会发生。这项研究为构建具有不同颜色的结构可调谐的荧光超分子材料提供了一种简便的方法。
