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.
