heal.abstract	In this work, a new [2]rotaxane consisted of a diazobenzene containing α-conjugated linear compartment, including the 4,4-bipyridyl moiety and α-cyclodextrin (-CD) as the macrocyclic compartment, was synthesised with yields of nearly 57% and fully characterised. α-CD easily assembled with the linear compartment and suitable bulky ends (stoppers) in water to give a new [2]rotaxane. The characterisation of this supramolecular compound was accomplished using several spectroscopic techniques such as1H NMR,13C NMR and 2D NMR spectroscopy, powder X-ray diffraction, fourier transform infrared spectroscopy, induced circular dichroism and UV-vis spectrophotometry, as well as scanning electron microscopy and Energy Dispersive X-ray. Furthermore, the reversible E-Z photoisomerisation of both [2]rotaxane and its molecular dumbbell was investigated by irradiation with UV light. © 2012 Copyright Taylor and Francis Group, LLC.	en
