Existing fluorescent probes for palladium (Pd) species detection have revealed their vulnerabilities, such as low sensitivity, poor anti-interference ability and long reaction time. In order to develop a faster and more accurate detection method for palladium species at extremely low concentrations, in this study, we designed a novel ratiometric AIEE/ESIPT probe (HPNI-1) based on the Tsuji-Trost reaction for Pd. According to the data obtained, the probe was able to detect Pd species with an ultra-high anti-interference ability (Pd : other metals = 1 : 1000), rapid detection time (within 2 minute) and ratiometric fluorescent signal changes with a 1.34 nM detection limit. This study not only proves that existing methods can be improved but also provides future prospects for HPNI-1 as one of the greatest probes for Pd species detection.
现有的用于检测钯（Pd）物种的荧光探针已暴露出其弱点，如灵敏度低、抗干扰能力差和反应时间长。为了开发一种能在极低浓度下更快、更准确地检测钯物种的方法，在本研究中，我们基于钯的辻 - 特罗斯特反应设计了一种新型的比率型聚集诱导发光增强/激发态分子内质子转移探针（HPNI - 1）。根据所获得的数据，该探针能够以超高的抗干扰能力（钯：其他金属 = 1：1000）、快速的检测时间（2分钟内）以及比率型荧光信号变化来检测钯物种，检测限为1.34 nM。本研究不仅证明了现有方法可以改进，还为HPNI - 1作为检测钯物种的最佳探针之一提供了未来前景。
