functionalized acyclic CB[n]-type receptors (2-4) by click chemistry. The compounds have good solubility in water (≥8 mM) and do not undergo strong self-association (Ks ≤ 903 M-1). We measured the binding constants of 2-4 toward guests 9-24 and compared the results to those obtained for the prototypical acyclic CB[n]-type receptor 1. The X-ray crystal structure of 4 is also described.

A polishing composition contains cerium oxide particles of 50 nm or more to 160 nm or less in average secondary particle diameter and at least one kind of nitride film polishing accelerating agent selected from a group consisting of a methonium compound and a primary or secondary alkanolamine compound, wherein a concentration of the methonium compound is 1.0 mass % or less, and a pH is 3.5 or more to less than 6. A polishing method includes bringing a surface to be polished of an object into contact with a polishing pad while a polishing composition according to claim

is supplied to the polishing pad, and polishing by a relative movement between the surface of the object and the polishing pad.
