摘要
A fluorescence-enhanced probe PY, which is based on integration of pyrene moiety and amino acid group,was developed for the orthogonal recognition of In3+ and Al3+ by the quick formation of 1:1 complex. 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.
