Application

1,2-Diaminoanthraquinone (DAQ) can be used as a building block to prepare:
  • Imidazoanthraquinone derivatives via palladium-catalyzed Suzuki–Miyaura and Sonogashira coupling reactions.
  • Anthra[1,2-d]imidazole-6,11-diones by reacting with various aldehydes in the presence of phosphotungstic acid/PEG-400 catalyst.
  • DAQ-containing polymer materials are applicable as solid-state colorimetric sensors for nitrite anion and nitric oxide.

The role of nitric oxide (NO) as a putative mediator of neuronal death can be understood best if NO is detected directly. For this purpose, we developed a new sensitive method that for the first time directly captures released NO
