The photoionization yields of N-alkylphenothiazines solubilized in either cationic or anionic micelles at 77 K were studied as a function of both alkyl and surfactant chain length. The results are compared to similar work on sulfonated N-alkyl-phenothiazines. The location of the phenothiazine moiety with respect to the micelle-water interface together with cation-water interactions is a major factor controlling the photoionization efficiency. The position of the N-alkylphenothiazine chromophore within a micelle can be altered by changing the alkyl chain length. The photoefficiency is also affected by the surface charge of the micelle.
