Abstract
Abstract In this paper we report a variable temperature EPR investigation on auto-assembling inclusion compounds of tris( o -phenylenedioxy)cyclotriphosphazene (TPP), the nitroxide radical methyl ester of the 16-doxyl-stearic acid (16-dox), and diamagnetic co-guests of various polarities. By playing with the nature of the co-guest and the concentration of the radical we obtained radicals isolated, or in 1D clusters. Local order, dynamics and orientation of the guests have been obtained by simulations of the spectra of spin-carrying guests envisaged as probes. For the simulations, intra-channel and inter-channel radical pairs and trimers magnetic interactions have been modellized. The interest of similar compounds for 1D magnetic materials is discussed.
