Abstract

The dimeric (gemini) as well as metallosurfactants exhibit enhanced physicochemical properties compared to conventional surfactants. By uniting the benefits of both, a series of novel dimeric metallosurfactants of the type (12-2-12)MBr4] (M = Co, Ni, Cu and Zn) was successfully prepared with the reaction of the dimeric surfactant bis(N,N-dimethyl-N-dodecyl)ethylene-1,2-diammonium dibromide, 12-2-12, and the MBr2 salt. Structures and magnetic properties of the materials were studied comprehensively in the solid state, while their micellization was explored in solution. The obtained results unveil that the incorporation and the choice of transition metal more significantly influence surfactants' structures ((12-2-12)2+ cations adopt V-, U- or trans-conformations) and the magnetic features (metal ions form 1D or 2D magnetic lattice) than their solution properties. However, all synthesized metallosurfactants display improved self-assembly properties compared to the metal-free precursor. The investigated systems represent a fruitful platform for the development of multifunctional materials, as they are simple to produce, can be obtained in high yields, and show advanced properties both in solution and in the solid state. Notably, this work unveils a simple approach for the design and synthesis of novel low-dimensional magnetic systems of great potential for future spintronic and optoelectronic devices.
