Steps:
2,3-Diaminophenazine synthesis
2,3-Diaminophenazine was prepared according to the procedurereported in the literature [28]. 6 mL of 0.08 mol/L aq FeCl3solution was added into 30 mL of a 0.02 mol/L aqueous 1,2-phenylenediamine solution with fast stirring at ambient temperature. Aquick color change from purple-black to reddish-brown wasobserved upon the addition of FeCl3. After 5 h, white precipitatewas formed. The solid was washed many times with deionizedwater, and then separated by centrifugation and sublimated toachieve compound 1 as a white crystal.
