The inclusion behavior of [5-(4-93-trymethylammonium0propyloxyphenyl)-1-,15,20-triphenylporphyrin] chloride (1H2), 2-[2-(2-(4-(10,15,20-triphenyl-5-porphyrinyl)-phenoxy)-ethoxy)ethoxy]ethanol (2H2), and their Mn(III) derivatives 1MnCl and 2MnCl, respectively, in micellar phase of CTAB and Brij 35 aqueous solutions have been studied by means of several spectroscopic techniques. The results obtained show that a suitable functionalization of the periphery of the porphyrin macrocycle influences the specificity of their binding to different micellar aggregates. This, consequently, allows for a tuning of the location and the aggregation mode of inclusion. These findings give a sound basis for the interpretation of the, earlier reported, P450 biomimetic catalytic activity featured by 1MnCl and 2MnCl in the epoxidation of some probe olefins.

Abstract
The inclusion behavior of [5-(4-93-trymethylammonium0propyloxyphenyl)-1-,15,20-triphenylporphyrin] chloride (1H2), 2-[2-(2-(4-(10,15,20-triphenyl-5-porphyrinyl)-phenoxy)-ethoxy)ethoxy]ethanol (2H2), and their Mn(III) derivatives 1MnCl and 2MnCl, respectively, in micellar phase of CTAB and Brij 35 aqueous solutions have been studied by means of several spectroscopic techniques. The results obtained show that a suitable functionalization of the periphery of the porphyrin macrocycle influences the specificity of their binding to different micellar aggregates. This, consequently, allows for a tuning of the location and the aggregation mode of inclusion. These findings give a sound basis for the interpretation of the, earlier reported, P450 biomimetic catalytic activity featured by 1MnCl and 2MnCl in the epoxidation of some probe olefins.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
