M. Linke et al., COMPLETE REARRANGEMENT OF A MULTI-PORPHYRINIC ROTAXANE BY METALATION-DEMETALATION OF THE CENTRAL COORDINATION SITE, Chemical communications, (22), 1998, pp. 2469-2470
A new multiporphyrinic [2]rotaxane has been made in which a gold(III)
porphyrin is part of the ring; rotation of the stringlike fragment wit
hin the ring between two diametrically opposed positions is triggered
by metallation-demetallation of the central coordination site.
