    STUDIA CHEMIA - Issue no. 4 / 2015  

Authors:  DAN PORUMB.
  Abstract:   A convenient procedure for the synthesis of 3-diethylamino-7-phenylaminophenothiazin-5-ium iodide was developed and the solvatochromism of this blue dye was examined by means of UV-Vis spectroscopy. The maximum of the absorption wavelength was detected in the range 550-665 nm, the asymmetrical phenothiazinium dye exhibiting a large red shift upon variation of the solvent structure from aprotic dipolar (THF, DMF) to protic solvents (water, methanol, acetic acid). 

Keywords: phenothiazin-5-ium, cationic dye; UV-Vis absorption, solvatochromism
