Precise modulation of cation binding affinity was accomplished by the efficient two-step conversion of a newly synthesized macrocyclic ligand H4L2 having a 24-crown-8-like cavity and two saloph moieties. The conversion of H4L2 into L2Ni2 resulted in a 120-fold enhancement in the binding affinity towards Cs+. The electrochemical reduction of L2Ni2 further enhanced the recognition ability by 3 orders
阳离子结合亲和力的精确调节是通过新合成的具有24冠8样腔和两个saloph部分的大环
配体H 4 L 2的有效两步转化来实现的。H 4 L 2转化为L 2 Ni 2导致对Cs +的结合亲和力提高了120倍。L 2 Ni 2的电
化学还原进一步将识别能力提高了3个数量级。
