摘要

A new series of cytosine-substituted metalloporphyrin conjugates (containing Co(II) and Zn(II) as the coordinated metals) were designed and investigated as nucleotide receptors in PVC-membrane-based ion-selective electrodes under neutral conditions. The potentiometric results indicate that these systems, in particular the Co(II)-containing complex, may be potentially useful sensors for complementary nucleotide substrates in the presence of 10 mol% tridodecylmethylammonium chloride (K(Pot.)(5'-GMP/5'-AMP)= 0.045).
