DAAD hydrogen bond donor (D) and acceptor (A) arrays 1 were synthesized and the recognition of the complementary ADDA substrates 2 and heterodimer formation by four hydrogenbonds was measured by 1H NMR titrations. The binding energy of a sterically not crowded dimer is in accordance with the value calculated from increments.
合成DAAD氢键供体(D)和受体(A)阵列1,并通过1 H NMR滴定测量互补的ADDA底物2的识别和通过四个氢键形成的异二聚体。空间上不拥挤的二聚体的结合能与根据增量计算的值一致。
