Abstract

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.
