Abstract

A selective Pd probe is described, which shows fluorometric and colorimetric responses towards both Pd(2+) ions and Pd(0)-complexes with excellent sensitivity and potential application. The fluorescence quenching effect of Pd(2+) is inhibited by filling up d-orbitals after the reduction from Pd(2+) (open-shell) to Pd(0) (closed-shell).

摘要

描述了一种选择性 Pd 探针，它对 Pd(2+)离子和 Pd(0)-配合物均具有荧光和比色响应，具有优异的灵敏度和潜在应用。从 Pd(2+)（开壳）还原为 Pd(0)（闭壳）后，填满 d 轨道会抑制 Pd(2+)的荧光猝灭效应。
