Abstract
Steady organic-inorganic perovskite hybrids with [H22-AMP]3/2Fe(CN)6, [H23-AMP]3/2Fe(CN)6 and [H24- AMP]3/2Fe(CN)6 (AMP = aminomethylpyridine) were formed in the air. Each structure shows an unusual layered organic-inorganic structural type. The hybrids enveloped in paraffin, respectively, to prepare hybrid paste electrode (HPE) (HPE-2 with [H22-AMP]3/2Fe(CN)6, HPE-3 with [H23-AMP]3/2Fe(CN)6, HPE-4 with [H24-AMP]3/2Fe(CN)6). Three hybrids in HPEs showed good electrochemical characteristics. The sequence of redox activity is [H24- AMP]3/2Fe(CN)6 > [H22-AMP]3/2Fe(CN)6 > [H23-AMP]3/2Fe(CN)6 and that of electrocatalytical characteristics is [H23- AMP]3/2Fe(CN)6 > [H22-AMP]3/2Fe(CN)6 > [H24-AMP]3/2 Fe(CN)6. Three hybrids have been employed to investigate the interaction between DNA and three hybrids. The results indicate that between [H23-AMP]3/2Fe(CN)6 and DNA is useful and [H23-AMP]3/2Fe(CN)6 can detect the hybridization of DNA. And the interaction between [H22-AMP]3/2Fe(CN)6 and DNA and between [H24-AMP]3/2Fe(CN)6 and DNA is slender. Three HPEs display remarkable electrochemical sensitivity and stability. The variation coefficients (RSD) of repeatedly successive and interval assays are less than 2.5%. The chemical and physical stability of three hybrids is satisfactory.
