Synthesizers synthesizers [12024]. In the field of mechanically linked artificial photosynthetic models, a single sophisticated study Inside the field of mechanically linked artificial photosynthetic models, one elegant by Weiss, Hyashi and Guldi Guldi has been lately published, in which the ZnP 60 study by Weiss, Hyashi and groupsgroups has been not too long ago published, in which the rotaxane was assembled by the AMT method (Figure 15) [125]. Specifically, treatment ZnP 60 rotaxane was assembled by the AMT method (Figure 15) [125]. Especially, of a ZnP(II)porphyrinate-based macrocycle with [Cu(MeCN) [Cu(MeCN)4 formation of therapy of a ZnP(II)porphyrinate-based macrocycle with 4 ][PF6 ] led to][PF6] led to bimetallic complex 28, in which the which the appended bidentate phen moiety seformation of bimetallic complicated 28, inappended bidentate phen moiety sequesters and positions thepositions the Cu(I) ion inside the macrocycle.
