About this Chemistry article
Red-emitting rhodamine-based probe with large Stokes shift for ClO− detection by Qin Liang; Wenqiang Chen; Xiaojie Ren; Xiangzhi Song is a Chemistry article available to read on EtoBox.
A fluorescent rhodamine dye, HN, was prepared by introducing tetrahydroquinoxalinyl donor, which displayed far-red emission (687 nm), large Stokes shift (84 nm), and relatively high fluorescent quantum yield (0.33). Based on HN dye, a fluorescent probe, HN-HClO, was developed for hypochlorite (ClO À ) detection. The probe HN-HClO exhibited fast response time (within 100 s), excellent sensitivity (LOD 1⁄4 74 nM), and good selectivity toward ClO À . The probe HN-HClO was capable of imaging ClO À in both living cells and zebrafish. It could also monitor the endogenously generated ClO À in the MPOcatalyzed system.
It is typically read by researchers, students, and practitioners in Chemistry.
