A cucurbit[5]uril analogue from dimethylpropanediurea-formaldehyde condensation

A new host Me 10 TD[5] was prepared for the first time from propanediurea-formaldehyde condensation. Me 10 TD[5] is soluble in both water and common organic solvents, and binds protonated amines in a 1 : 2 stoichiometry in H 2 O with the K 1 and K 2 values on the order of 10 3 M −1 . The self-assemb...

Zusammenfassung:A new host Me 10 TD[5] was prepared for the first time from propanediurea-formaldehyde condensation. Me 10 TD[5] is soluble in both water and common organic solvents, and binds protonated amines in a 1 : 2 stoichiometry in H 2 O with the K 1 and K 2 values on the order of 10 3 M −1 . The self-assembly of Me 10 TD[5] with 1,4-xylylene diamine dihydrochloride results in the formation of a linear supramolecular polymer. A new cucurbit[5]uril-like macrocycle has been synthesized and shows good solubility in water and organic solvents.
