摘要	A trinuclear cobalt-based multifunctional coordination polymer with a dual loop pseudo-rotaxane motif, namely [Co-3(DPFE H+)(2)(sdba(2-) )(4)(OH-)(2)](DPFE 2H(+))(CH3CN) (1), has been synthesized by a mixed ligand strategy under hydrothermal conditions (DPFE = 2,7-di(pyridin-4-yl)-9H-fluorene, H(2)sdba = 4,4'-sulfonyldibenzoic acid). Compound 1 has 1D + zero-dimensional (0D) -> 1D armed pseudo-polyrotaxane character, in which the 1D dual ring chain [Co-3(COO-)(4)(OH-)(2)(sdba(2-))(4) is threaded by doubly protonated free DPFE ligands. The trinuclear cobalt cluster and p-electron rich system involving the ligands jointly endow compound 1 with magnetism, photocatalytic and electrochemical properties. Magnetic property measurements of 1 indicate that there exists weak antiferromagnetic coupling in the trinuclear [Co-3(COO-)(4)(OH-)(2)] unit, the experiments of photocatalytic degradation of dyes demonstrated that 1 has good catalytic activity for the degradation of methylene blue (MB) and the electrochemical results show that compound 1 exhibits a specific capacitance of 52.25 F g(-1) at a current density of 1 A g(-1) and retains 93.75% specific capacitance after 960 cycles.
