Dendritic-macrocyclic polyradicals consist of small dendritic branches which may be connected to calix[4]arene macrocyclic cores via 3,4 -biphenylene linkers. Polyradicals 45-50 correspond spin dimers, trimers, and pentamers, as illustrated in Fig. 28. Their connectivity is consistent with ferromagnetic coupling scheme. 

Macrocyclic-macrocyclic polyradicals were designed to attain the scaling of S with the number of radical sites, thus allowing for attaining very large values of S in... 

Macrocyclic-macrocyclic polyradicals consist of macrocyclic branches connected to macrocyclic cores via bis(3,4 -biphenylene)methyl linkers (Figs 32 and 33). The connection of calix[4]arene-based macrocycles via bis(3,4 -biphenylene)methyl linkers provided special type of organic spin clusters, in which large component spins of the macrocycles were exchange coupled via much smaller spins 1/2 of the linkers, as illustrated in Figs 32 and 33 for polyradicals 51-53.8 112... 

High-spin polymers 57 and 58 consist of calix[4]arene-based macrocycles either linked or annelated via bis(3,4 -biphenylene)methyl linkers. Their design, including ferromagnetic-ferrimagnetic coupling scheme with unequal spin modules, was derived from macrocyclic macrocyclic polyradicals and annelated macrocyclic polyradicals (Fig. 38).
