Here, we describe a readily accessible AAAA-DDDD quadruple hydrogen-bonding array that exhibits exceptionally strong binding for a small-mol. hydrogen-bonded complex in a range of different solvents (Ka > 3 x 1012 M-1 in CH2Cl2, 1.5 x 106 M-1 in CH3CN and 3.4 x 105 M-1 in 10% vol./vol. DMSO/CHCl3).

Here, we describe a readily accessible AAAA–DDDD quadruple hydrogen-bonding array that exhibits exceptionally strong binding for a small-molecule hydrogen-bonded complex in a range of different solvents (K (a) > 3 × 10 (12) M (-1) in CH2Cl2, 1.5 × 10 (6) M (-1) in CH3CN and 3.4 × 10 (5) M (-1) in 10% v/v DMSO/CHCl3).
