Macro-arrays components

The examples reported above refer to pseudorotaxane species with a 1 1 thread/macrocycle ratio ([2]pseudoro-taxanes). It is also possible to obtain species exhibiting different stoichiometric ratios, as illustrated by the fascinating [5]pseudorotaxane formed from four cyclophane 4 + components and a Zn(II)-phthalocyanine with appended four polyether substituents carrying 77-electron-rich hydroquinone units [35]. Examples of pseudorotaxanes are known in which a macrocycle is threaded by two linear components [36] and a linear component threads two macro-cycles [37]. Long linear arrays can be obtained by using homoditopic threads and macrocycles [38] homogeneous or...
