Synthesis of polyhalo acridones as pH-sensitive fluorescence probes
摘要:
Polyhalo isophthalonitriles were reacted with substituted anilines and subsequently cyclocondensed in the presence of sulfuric acid to give polyhalo acridones. These polyhalo acridones were proven to be useful as pH-sensitive fluorescent probes for a wide range of acidic and basic conditions. (C) 2010 Elsevier Ltd. All rights reserved.
