摘要: In this article, eight fluoroquinolone analogs showed intriguing chemiluminescence (CL) diversity in the presence of peroxynitrous acid. Compared to current literature, these studied fluoroquinolones exhibit many novel characteristics on CL spectra, CL quantum yield and reaction routes. Furthermore, when the distribution of CL was comparable to its fluorescence, a diversity of differences between the analogs were observed. These results indicate that the hydroxyl radical (OH)-O-center dot and excited state peroxynitrous acid may account for these observations. This discovery could deepen the understanding of mechanisms in CL systems and change the traditional theories about CL phenomena. (C) 2016 Elsevier B.V. All rights reserved.
