“…For enhancing the capacitance, a composite was synthesized by combining PPy with one-dimensional iridium complex crystals [(C 2 H 5 ) 4 N] 0.55 [IrCl 2 (CO) 2 ] though an in situ electrodeposition process. 616 This hybrid composite electrode displayed the maximum C sp of 590 F g −1 . PPy has also been integrated with polyoxometalate (POM)-based MOFs.…”

“…1-D nanocrystals and conducting polymer composites were also created. Crystals of β-akaganeite (β-Fe 3+ O(OH,Cl)) with PEDOT [46,47] and crystals of iridium complex ([IrCl 2 (CO) 2 ] À ) with PPY [48] are examples of 1-D composites containing conducting polymer and crystal metalloorganic complexes. The advantage of fabrication of these materials is the possibility of their preparation by in-situ one-step or two-step approach, respectively.…”

“…First, needles of the iridium complex were prepared by electrochemical oxidation of (AsPh 4 )[IrCl 2 (CO) 2 ]. Next, pyrrole was electropolymerized on the surface of the iridium needles [48]. Both the crystals size and thickness of the polymer can be easily controlled very simply using the reaction conditions such as concentration of compounds, different reaction times, and kind of solvent.…”

Recent advances in the study of the synthesis, structure and applications of 1-D composites containing conducting polymers are discussed in this review. Conducting composites can form 1-D structures with metal and metal oxides, 1-D carbon nanomaterials, semiconducting materials, crystals of metalloorganic complexes. Advanced synthetic approaches allow for the formation of well-organized structures with polymeric phase deposited both on the surface of 1-D material and inside of the 1-D tubes. 1-D polymeric wires can also serve as a matrix for the formation 1-D composites with other materials. 1-D nanocomposites containing conducting polymers exhibit many exceptional properties which allow for various practical applications including energy converting and energy storage devices, electronic nanodevices, chemical, electrochemical and biochemical sensors, catalysis and electrocatalysis.

Pyrrole-3-carboxylic acid was electropolymerized on a glassy carbon electrode in 0.1 M NaClO4/ACN, Et4NBF4/ACN using cyclic voltammetry. Urease (Urs) was immobilized onto PPCA modified GCE via covalent binding, exploiting EDC/NHS chemistry. Electrochemical impedance spectroscopy was used to investigate the interfacial behavior of Urs immobilized PPCA surfaces at open circuit potential. The impedance spectra were fitted before and after immobilization of Urs using equivalent circuits of R(C(R(Q(RW)))). After immobilization of Urs onto the PPCA matrix, the charge transfer resistance (RCT) increased for electrodes, which RCT of urease immobilized PPCA-NaClO4 matrixes were lower than that of the Urs immobilized PPCA-Et4NBF4 matrixes indicating higher charge transfer ability. A decrease in double layer capacitance (Cdl) values when Urs was immobilized at the PPCA-NaClO4 electrode surface was observed, whereas an increase at the PPCA-Et4NBF4 electrode surface was observed. Urs immobilized electrodes resulted in a n-type semiconducting behavior revealing a positive slope. An increase in acceptor concentration of the electrodes, and a shift of the EFB to more positive values with increasing amount of urease was observed. The Urs based electrode (PPCA-NaClO4-Urs) was used for detection of urea, which was detected in range of 0.9 to 14 mM with a detection limit (LOD) of 8.28 μM.
