A new quadruple hydrogen-bonding module with a DDAA array: formation of a stable homodimer without competition from undesired hydrogen-bonded dimers.
A new DDAA hydrogen-bonding module (UImp-2), based on a ureidoimidazo[1,2-a]pyrimidine structure, forms a highly stable homodimer (K(dim) > 1.1 x 10(5) M(-1) in CDCl(3)) without competition from undesired hydrogen-bonded dimers.
