2D organic-inorganic nanosheets via self-assembly of a pillar[6]arene and polyoxometalate for enhanced degradation efficiency.

Construction of 2D hybrid nanosheets was realized through a self-assembly strategy using a pillar[6]arene (P-6) and polyoxometalate (POM) in water. More fascinatingly, the macrocyclic cavity of P-6 could impose a restriction effect on the lamellar arrangement and significantly enhance the catalytic ability of nanosheets for dye degradation.
