Urea, with its ability to both accept and donate hydrogen bonds, serves as an ideal structure for supramolecular synthesis. Recent developments have focused on various functions of urea derivatives, including the formation of discrete and continuous urea-urea intermolecular hydrogen bonds, as well as the development of catalytic reactions based on the molecular recognition ability of the ureido group.
Urea, which has both hydrogen bond acceptor and donor moieties, is an ideal structure for a supramolecular synthon. Various supramolecules having ureido group(s) have been widely developed. This article summarizes recent developments of urea derivatives that exhibit various functions: i) supramolecular capsules that form discrete urea-urea intermolecular hydrogen bonds, ii) supramolecular polymers that form continuous urea-urea intermolecular hydrogen bonds, iii) supramolecular gels that form continuous urea-urea intermolecular hydrogen bonds, iv) artificial host molecules based on the molecular recognition ability of the ureido group, and v) catalytic reactions developed by utilizing the molecular recognition ability of the ureido group.
