Novel Bis-Crown-Ether Derivatives for Potassium Sensors


A variety of bis-benzo-15-crown-5 derivatives were designed and studied with the aim of developing potassium sensors of biological relevance. The significant advantages of bis-/o-nitrophenyl/urethanes have been explained by the existence of NO2-NH hydrogen bonds proved indirectly. The performance characteristics of the prime ligands based sensors were compiled together with potassium assays in biological matrices. © 1989, Taylor and Francis Group, LLC. All rights reserved.
