3-Morpholino-7-[N-methyl-N-(4′-carboxyphenyl)amino]phenothiazinium Chloride

Abstract

The synthesis of 3-morpholino-7-[N-methyl-N-(4′-carboxyphenyl)amino]phenothiazinium chloride is reported here. Interestingly, non-symmetric phenothiazinium salt is functionalized with a carboxylic acid group that allows the easy and stable anchoring on metal oxides. In addition, the morpholine unit reduces the dye aggregation tendency; thus, improving its potential applications in the biomedical and photo-electrocatalytic field.
