| Popis: | Interactions of cationic tetrakis (N, N´, N´´, N´´´- tetramethyltetra-3, 4-pyridinoporphyrazinatozinc (II) [Zn (tmtppa)] with various anionic micelles of surfactants n- alkyl sulfonate and sulfate (n=11, 12, 14) have been investigated spectrophotometrically at 25 ◦C in premicellar and postmicellar region. The results have shown that with increasing the alkyl chain length of surfactants, the maximum absorbance of Zn (tmtppa) shifted to a higher wavelength and binding affinity of Zn (tmtppa) to anionic micelles increases. This confirms that the surfactant micelle, which has a longer alkyl hydrocarbon chain, enables greater solubilization of porphyrazine. Thus, the hydrophobic interaction of the porphyrazine with micelles increases in the order: C11H23SO3Na < C12H25SO4Na < C14H29SO3Na..
