Metallomicellar Systems Based on the Complexes of 1-Hexadecyl-4-aza-1-azoniabicyclo[2.2.2]octane Bromide with Transition Metal Nitrates

Аннотация

Potentiometry, fluorimetry, dynamic light scattering, and transmission electron microscopy were used to study the aggregation properties of the complexes 1-hexadecyl-4-aza-1-azoniabicyclo[2.2.2]octane bromide with transition metal nitrates [Cu(II), Ni(II), Co(II), and La(III)]. The critical micelle concentrations, aggregation numbers, the degree of counterion binding to micelles, the size of aggregates, and electrokinetic potentials were determined. The complexes exhibited a high antimicrobial activity, and some of them proved to be more potent than the reference drugs.
