Percarbonate is an important oxidant that is widely used in industrial applications and daily life. In this study, a simple colorimetric and fluorescence method for percarbonate determination using resorufin-based probe 1, carrying a pivaloyl protection group as a signaling switch, was developed. Probe 1 exhibited selective and sensitive signaling behavior for percarbonate via perhydrolysis of the pivaloyl group by hydrogen peroxide that was produced from percarbonate, in the presence of commonly encountered metal ions and anions. Among the esters tested as signaling switches, pivalate was optimal owing to its resistance to spontaneous hydrolysis and high signaling speed under the employed conditions. The detection limit for percarbonate was estimated to be 0.45 μM. The probe was applied to the analysis of percarbonate in domestic bleach using a scanner as a field-oriented signal-capturing device.

过碳酸盐是一种重要的氧化剂，广泛用于工业应用和日常生活中。在这项研究中，开发了一种简单的比色法和荧光法，用于使用过氧苯酚的探针1进行过碳酸盐的测定，该探针带有新戊酰保护基作为信号转导。探针1在常见的金属离子和阴离子存在下，过碳酸盐通过过氧化氢产生的过氧化氢对新戊酰基进行过水解，对过碳酸盐具有选择性和敏感的信号传导行为。在作为信号转换开关测试的酯中，由于新戊酸酯在使用条件下具有抗自发水解和高信号传输速度的特性，因此是最佳的。过碳酸盐的检出限估计为0.45μM。该探针使用扫描仪作为现场定向信号捕获设备，用于分析家用漂白剂中的过碳酸盐。
