Abstract:

A cross-linked polymer composed of polyethylenimine (PEI) reacted with 1,4-dibromobutane coated on a glassy C electrode (GCE) and contg. neg. charged ions, Fe(CN)63-/4-, is proposed as a ref. electrode in org. solvents. The system exhibits a relatively stable potential (±10 mV) over a period of several days in MeCN and a reasonable potential stability for several hours in DMF and CH2Cl2. The different parameters that affect the behavior of the GCE/PEI/Fe(CN)63-/4- are characterized. [on SciFinder(R)]
