Photoreversible switching between assembly and disassembly of a supramolecular polymer involving an azobenzene-bridged pillar[5]arene dimerElectronic supplementary information (ESI) available: Experimental section and characterization data. See DOI: 10.1039/c3cc44384a

We report a photo-reversible switching system between assembly and disassembly of a supramolecular polymer consisting of an azobenzene-bridged pillar[5]arene dimer. A photo-reversible switching system between assembly and disassembly of a supramolecular polymer is reported using an azobenzene-bridged pillar[5]arene dimer.
