Abstract Nitro derivatives of bis-crown ethers with urethane (2), ether (10), and ester (9, 16) linkage not being able to form hydrogen bridges were synthesized, and their K+ selectivities were determined. A remarkable effect of the NO 2 group on the selectivity was observed when a NO 2… NH hydrogen bond could be formed while the others showed only slight improvement in general electroanalytical parameters. Several analogues without the ...
