  Chromogenic bis(urea) spherands: synthesis and complexation of lithium and sodium ions

  摘要：

  Syntheses of two novel 18-membered bis(urea) spherands bearing 2,4,6-trinitroanilino and 4-(diethyl-amino)phenylazo chromophores are described. The UV-vis spectral changes in the presence and absence of Na+ and Li+ ions are reported at pH optima. Chromogenic spherand 2 exhibits selectivity for Na+ over Li+ in chloroform-water extractions. In contrast, Li+ ions are bound better than Na+ by both spherands in homogeneous aqueous media. The pK(a) values are determined for spherand 2 with Na+ and Li+ in 10% aqueous diethylene glycol monoethyl ether (DEGMEE). The extraction constants (K(ex)) for K+, Na+, and Li+ are determined for 2 in chloroform saturated with water, and the extraction selectivity order is Na+ > Li+ > K+.
