Catenanes diazapyrenium

Figure 13.22 The circumrotation of the tetracationic cyclophane component of catenane 254+ can be controlled reversibly by adding-protonating -hexylamine that forms a charge transfer adduct with the diazapyrenium unit of the catenane. Figure 13.22 The circumrotation of the tetracationic cyclophane component of catenane 254+ can be controlled reversibly by adding-protonating -hexylamine that forms a charge transfer adduct with the diazapyrenium unit of the catenane.
Upon addition of CF3S02H, protonation of -hexylamine occurs and the adduct formed between -hexylamine and the diazapyrenium unit of the catenane is destroyed. Consequently, the original coconformation associated with 254+ is... [Pg.402]
