摘　　要：A meso–molecular muscle was prepared by capping the[c2]daisy chain based on a mono-functionalized copillar[5]arene with an imidazolium group in its axle.From its crystal structure,we observed that it was a cyclic dimer composed of two mirror image subcomponents,a pR-and a pS-copillar[5]arene.Their conformations were fixed by the doubly interlocked mechanical bond.By comparison of the^1H NMR and COSY spectra,we found that the length of this meso–molecular muscle could be controlled not only by the solvents,but also by the counter anions.
