摘要：
A chemosensor NBD-PMA with colorimetric and fluorometric responses for Pd2+ cations has been described. NBD-PMA selectively coordinated Pd2+ cations with a colour change from bright yellow to pink, which enabled detection of Pd2+ cations in environmental water samples with the naked eye. NBD-PMA also exhibited high selectivity and sensitivity for Pd2+ cations in fluorometry even in the presence of other metal cations, which makes it practically applicable for detecting Pd2+ cations in environmental samples and in living cells.
