PY shows high selectivity and sensitivity for In3＋ in NaOAc/HOAc（pH 4.8） buffer solution but rather for Al3＋ in methanol. Moreover, this probe shows good cell permeability, and the recognition of In3＋ by PY was successfully applied in bioimaging, which was the first example for detection of this metal ion in living cells.展开更多
