Synthesizers synthesizers . Within the field of mechanically linked artificial photosynthetic models, a single elegant study Within the field of mechanically linked artificial photosynthetic models, one particular elegant by Weiss, Hyashi and Guldi Guldi has been not too long ago published, in which the ZnP 60 study by Weiss, Hyashi and groupsgroups has been lately published, in which the rotaxane was assembled by the AMT strategy (Figure 15) . Especially, treatment ZnP 60 rotaxane was assembled by the AMT strategy (Figure 15) . Specifically, of a ZnP(II)porphyrinate-based macrocycle with [Cu(MeCN) [Cu(MeCN)4 formation of remedy of a ZnP(II)porphyrinate-based macrocycle with 4 ][PF6 ] led to][PF6] led to bimetallic complicated 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. As Cu(I) ions As Cu(I) ions are questers and Cu(I) ion inside the cavity from the cavity of the macrocycle. are the promoters of promoters of “click reactions”, an endotopic an endotopic catalyst that within the presthe “click reactions”, complicated 28 is complex 28 is catalyst that in the presence of alkynyl fullerene 29 and azide stopper azide stopper 30 promotes the “click reaction” by way of ence of alkynyl fullerene 29 and30 promotes the “click reaction” through the macrocycle cavity to yield cavity to yield 31 in rotaxane following removal in the removal with Cu(I) the macrocycle target rotaxanetarget48 yield,31 in 48 yield, afterCu(I) ionsof the EDTA.
