The hydrothermal reaction of 4,4′-dicarboxybiphenyl sulfone and dysprosium(III) nitrate in the presence of L-histidine yielded the first 2D → 2D polyrotaxane lanthanide–organic framework, which possesses both polyrotaxane and polycatenane topology features. Magnetic investigations indicated that it is a field-induced single-molecule magnet with two-step magnetic relaxation processes.
