Abstract

In this article ferrocene monoamino phenyl boronic acid (FcMAPBA) and ferrocene diamino phenyl boronic acid (FcDAPBA) were synthesized and characterized by 1H NMR and FTIR. Particular emphasis is given to cis-diol and saccharide binding affinities with ferrocene amino phenyl boronic acid (FcAPBAs) which was investigated by 1H NMR and CV (using sorbitol). Free and bound forms of derivatives were depicted from disappearance of boronic acid hydroxyls signal in 1H NMR spectra. The presence of two discrete peaks in the CV curves is in agreement with 1H NMR spectra, as the indication of cis-diol binding with saccharides. It was also proposed that this approach using potential shift difference in CV curves can be applied for surface confined glycated molecules detection.
