Abstract :
A series of cross-linked poly(2-hydroxyethylmethacrylate) (polyHEMA) films doped with 1,2-diaminoanthraquinone (DAQ) are described. The synthesis of the DAQ-containing polymers does not require any previous derivatization of the diamine. The films can be used as solid-state colorimetric sensors for nitrite anion as well as for aqueous and gaseous nitric oxide. Polymers show no appreciable leaching of DAQ even after six months of storage in water.
