[3]Rotaxane−Porphyrin Conjugate as a Novel Supramolecular Host for Fullerenes
摘要:
A new supramolecular host with good affinity toward fullerenes has been developed. This host having a tweezer-like shape is built on a [3]rotaxane scaffold and contains two free-base porphyrin moieties as recognition units for fullerenes. The ability of this tweezer to bind fullerenes strongly depends on the solvent system used and the size of fullerene.

by TRPL measurements with the shortest lifetime of 1.1 ns and FRET efficiency of 81.7% in comparison with the longer lifetime of 6.0 ns for mono-fluorophoric [2]pseudo-rotaxane polymer analogue before detection of HS−. The 1:1 host–guest molar ratio and the formation of the [2]pseudo-rotaxane polymer can be further verified using 1H NMR complexation and DOSY experiments. The effects of pH and temperature
