title: A cucurbit[5]uril analogue from dimethylpropanediurea-formaldehyde condensation.
abstract: A new host was prepared for the first time from propanediurea-formaldehyde condensation. is soluble in both water and common organic solvents, and binds protonated amines in a 1 : 2 stoichiometry in H2O with the K1 and K2 values on the order of 10(3) M(-1). The self-assembly of with 1,4-xylylene diamine dihydrochloride results in the formation of a linear supramolecular polymer.
