Paper 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.
