, p. 381 - 386 (2011)
Four novel chiral 22-crown-6 ethers 6a-b, 7a-b bearing hydroxyl side groups derived from rosin acid and BINOL were prepared in optically pure forms, and their enantiodiscriminating abilities towards protonated primary amines and amino acid methyl ester salts were examined by UV-vis titration methods. These receptors exhibited good chiral recognition towards the isomers (up to K D/KL = 6.02, ΔΔG0 = 4.45 kJ mol-1) and showed different complementarity to various chiral guests.

, p. 1863 - 1867 (2021/02/16)
Azo-crown ether-based photoswitching chiral phase transfer catalysts have been developed to control the catalytic activity by photoirradiation. Azobenzene binaphthyl crown ether (ABCE) can switch its reactivity and selectivity through structural transform

Linking struts containing Cram-like bisbinaphthyl[22]crown-6 with Zn 4O(CO2)6 joints affords metal-organic frameworks with chiral recognition sites that are highly designed, ordered and placed in a precise manner throughou
Binaphthyl metallomacrocycles for complexation of neutral molecules
Reichwein, Arjen M.,Verboom, Willem,Reinhoudt, David N.
, p. 358 - 366 (2007/10/02)
Binaphthyl salophen crown ethers 1 and 2, containing an immobilized electrophilic uranyl cation, were synthesized by cyclization of dialdehyde 10 with 1,2-benzenediamine (14) or cis-1,2-cyclohexanediamine (15), respectively, in the presence of Ba(2+) as a
