通过高效的两步转化新合成的大环配体H4L2,实现了阳离子结合亲和力的精确调制,该配体具有24冠8状腔和两个saloph基团。H4L2转化为L2Ni2后,对Cs+的结合亲和力提高了120倍。电化学还原后的L2Ni2进一步提高了3个数量级的识别能力。
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 of magnitude.
