In the present work, we investigated guest‐host interactions between the palmatine guest and the Q[8] host. The results revealed the formation of a 1:2 host‐guest inclusion complex accompanied by strong fluorescence emission. Using the palmatine@Q[8] inclusion complex as a fluorescent probe, we detect various metal cations, including alkali (A + ), alkaline earth (AE 2+ ), transition (Tr n+ ) and lanthanides (Ln 3+ ) metal cations. The probe underwent fluorescence quenching only with ferric metal cations, demonstrating its ability to specifically detect Fe 3+ ions.
