Organometallic Elaboration as a Strategy for Tuning the Supramolecular Characteristics of Aza-Crown Ethers
Smith, J. B., Camp, A. M., Farquhar, A. H., Kerr, S. H., Chen, C.-H., & Miller, A. J. M. (2019). Organometallic Elaboration as a Strategy for Tuning the Supramolecular Characteristics of Aza-Crown Ethers. Organometallics, 38(22), 4392-4398. https://doi.org/10.1021/acs.organomet.9b00462
Outfitting an aza-crown ether with an organotransition-metal pendant provides a mechanism for tuning its supramolecular properties. The binding affinity can be tuned by more than 2 orders of magnitude by changing the identity of the transition metal-center, altering the overall charge of the complex, or engaging in organometallic ligand substitution reactions. High Li+ selectivity (up to 29-fold higher affinity in comparison to Na+), proton-responsive behavior, and ion pair (ditopic) binding capabilities are observed in the metallacrown ethers.
