An alkaloid pain reliever, morphine, is an often abused drug. Chronoampero-metric MIP chemosensors have been devised for its determination [204]. In these chemosensors, a poly(3,4-ethylenedioxythiophene) (PEDOT) film was deposited by electropolymerization in ACN onto an ITO electrode in the presence of the morphine template to serve as the sensing element [204], Electrocatalytic current of morphine oxidation has been measured at 0.75 V vs AglAgCllKClsat (pH = 5.0) as the detection signal. A linear dependence of the measured steady-state current on the morphine concentration extended over the range of 0.1-1 mM with LOD for morphine of 0.2 mM. The chemosensor successfully discriminated morphine and its codeine analogue. Furthermore, a microfluidic MIP system combined with the chronoamperometric transduction has been devised for the determination of morphine [182] with appreciable LOD for morphine of 0.01 mM at a flow rate of 92.3 pL min-1 (Table 6). 

The -conjugated polyselenophene named PEDOS (182) the analog of poly-3,4-ethylenedioxythiophene (PEDOT) [281], one of the most successful conductive polymers, was obtained from 3,4-ethylenedioxyselenophene (89) using different polymerization techniques. These were oxidative chemical polymerization, solid-state polymerization, transition metal-mediated polymerization, and electrochemical polymerization (Scheme 46) [293, 294], The derivatives of PEDOS having the...

Poly(3,4-ethylenedioxythiophene) (PEDOT) is a particularly popular conducting polymer as it can have good conductivity and stability and has a low band gap, which is pertinent to its use in photovoltaic devices. A number of authors have now studied the electrochemical synthesis of this polymer in different ionic liquids. Lu et al. [77] first demonstrated the use of [C4mim][BF4] to electrodeposit PEDOT onto ITO, and its application in an electrochromic numeric display. 

In the meantime, this phenomenon has also been observed by other groups for thermosensitive polymer-based metal nanoparticles [77, 78]. Pich et al. have used microgel particles based on the copolymer of A-vinylcaprolactam (VCL) and ace-toacetoxyethyl methacrylate (AAEM) (PVCL/PAAEM) as the carrier system for the deposition of metal nanoparticles. The microgels were first modified with poly(3,4-ethylenedioxythiophene) (PEDOT) nanorods through an in situ oxidative polymerization process. Microgels with PEDOT nanorods in the shell were then used for the... 

Fig. 2.11. Three organic semiconducting polymers, (a) Polypyrrole, (b) plythipo-hene, and (c) poly(3,4-ethylenedioxythiophene) (PEDOT). All three have an sp conjugated backbone identical to polyacetylene. It is along the pi-bonds in this backbone that these materials exhibit carrier delocalization and electrical activity.

Fig. 3.10. Some of the more commonly encountered organic conductor materials (a) polypyrrole, (b) polyaniline, and (c) poly(3,4-ethylenedioxythiophene) (PEDOT). When combined with water soluble organic acids (e.g. sulfonic acids like benzosul-fonic acid) many of these polymers can form doped complexes which are highly conductive and can be dispersed into suspension. Substituted versions of these polymers which are self-doped have also been developed.

Three-layered EL device, ITO/poly(3,4-ethylenedioxythiophene) (PEDOT)/ dye-doped PVK/Bphen Cs/Al On an ITO electrode, PEDOT and then PVK were spin-coated from their toluene solution, and the solvent was removed under reduced pressure. Bphen and Cs were coevaporated under high vacuum below 10 Torr on top of the PVK layer, and then the A1 cathode was evaporated on the top of the Bphen Cs in the same way. 2,3,7,8,12,13,17,18-octaethyl-21//,23//-porphyrinplatinum(II)(PtOEP) was doped in the PVK layer by using a mixed solution of the Pt complex and PVK on spin-coating. Optimum conditions were obtained at a dopant concentration of 1.0 mol% and a PVK thickness of 100 nm. The EL spectrum is shown in Fig. 14-22. 

Poly(vinyl pyrrolidone) (PVP) was used by Nguyen et al. as a polymer matrix to prepare electrically conducting nano(micro)poly(3,4-ethylenedioxythiophene) (PEDOT) fiber non-woven web [50]. The electrical conductivity of the electrospun PEDOT non woven web was as high as 7.5 S cm when 1-propanol was used as the solvent. An electrochemical capacitor was assembled using one pair of the PEDOT nonwoven webs as the electrodes by a simple stack method, where metal plates were used as current collectors. They observed the electrochemical charge and discharge behavior of the capacitor, confirming that the PEDOT nonwoven web can be used as an electrode for flexible electrochemical capacitors.

Polymerization of the conducting polymer poly (3,4-ethylenedioxythiophene) (PEDOT) around living neural cells. Biomaterials 28,1539-1552. 

Various kinds of conducting polymers can work as coimter electrode in DSSC. Poly(3,4-ethylenedioxythiophene) (PEDOT), polypyrrole (PPy), PANI are most investigated polymer materials. With the development of nanomaterial, the nanostructure has been introduced into previously mentioned polymers. These polymers are readily deposited by either chemical or electrochemical polymerization process. And they are readily modified into aligned nanostructure that might enhance charge transport and surface area simultaneously (Sun et al., 2015a).
