ID molecular magnets

The first experimental confirmation of Glauber s prediction was shown with the material Co(hfac)2(NITPhOMe), based on a nitronyl nitroxide radical (Caneschi et al, 2001). Co(hfac)2(NITPhOMe) consists of alternating Co(hfac)2 and radical moieties arranged in ID arrays with a helical structure, and crystallizes in the P3i space group with a = b = 1.129 nm and c = 2.057 nm. A detail of the chain structure is depicted in Fig. 6.21. 

The temperature dependence of magnetic susceptibility x measured on single crystals reveals magnetic ID behaviour. Below 50 K x is strongly anisotropic with the trigonal axis corresponding to the easy axis of magnetization and therefore to 

An important characteristic of this material is the high spin value of the magnetic unit inside the chain (5 = 3). It is remarkable that with the small

However, these pentameric macrocycles are t) picaUy obtained after 15-16 steps with an overall yield of 1-2 % [45], greatly limiting their potential uses in targeting biological pentamers [39], searching such as novel ID molecular magnets, or as...
