“…These new materials, also called synthetic metals, can reach high electrical conductivity, very close to the value of some metals and offer an extensive possibility to modify the surface of conventional electrodes supplying fascinating properties [17]. It was found that they can be used in many areas, such as electrochromic materials [18], organic-based solar cells [19,20], organic field effect transistors [21,22] and organic light-emitting diodes [23,24]. Moreover, providing simplicity and high reproducibility in preparation, easiness in arranging the thickness of the film, compatibility with biological molecules, and possibility to produce at room temperature make electrochemically synthesized CPs charming in designing biosensors [25,26].…”

1-3,4-Dihydroxy phenylalanine called as l-Dopa is a precursor of dopamine and an important neural message transmitter and it has been a preferred drug for the treatment of Parkinson's disease. In this study, with regards to the synthesis of l-Dopa two types of biosensors were designed by immobilizing tyrosinase on conducting polymers: thiophene capped poly(ethyleneoxide)/polypyrrole (PEO-co-PPy) and 3-methylthienyl methacrylate-cop -vinylbenzyloxy poly(ethyleneoxide)/polypyrrole (CP-co-PPy). PEO-co-PPy and CP-co-PPy were synthesized electrochemically and tyrosinase immobilized by entrapment during electropolymerization. l-Tyrosine was used as the substrate for l-Dopa synthesis. The kinetic parameters of the designed biosensors, maximum reaction rate of the enzyme (V max) and Michaelis Menten constant (K m) were determined. V max were found as 0.007 mol/(min electrode) for PEO-co-PPy matrix and 0.012 mol/(min electrode) for CP-co-PPy matrix. K m values were determined as 3.4 and 9.2 mM for PEO-co-PPy and CP-co-PPy matrices, respectively. Optimum temperature and pH, operational and shelf life stabilities of immobilized enzyme were also examined.

“…The difference of optical band gap is particularly owed to the different molecular structures and the number of electron donating functional groups. [42,43] Both of them have relatively small band gap, so the electron transition is easy to occur. It is suitable for the applications in photoelectric materials, especially for O1.…”

Two conjugated ethynyl-linked oligomers, oligo(benzodithiophene-ethynylene-benzothiadiazole) (O1) and oligo(benzodithiophene-ethynylene-carbazole) (O2), were synthesized by Sonogashira coupling reaction. Their degrees of polymerization were 7 and 10, respectively. Their photophysical and electrochemical properties were investigated. O1 exhibitd two strong absorption bands at 404 nm and 483 nm, and O2 at 401 nm and 429 nm. The results of UV-Vis, cyclic voltammetry (CV) and theoretical calculations showed that O1 has a narrower band gap than O2. The conductivities of O1 and O2 were 1.05×10 −15 and 6.98×10 −16 S/cm, respectively, and would increase to 1.23×10 −10 and 1.05×10 −10 S/cm after doping with iodine.

“…Organic semiconductors have attracted considerable scientific and industrial interest for applications in organic electronics and optoelectronics including organic field‐effect transistors (OFETs),1–14 organic light emitting diodes (OLEDs),15–18 and organic photovoltaic cells (OPVs) 12, 19–23. In particular, polymer semiconductors have been widely studied because of their unique advantages such as chemical tunability, compatibility with plastic substrates, structural flexibility, and favorable solution processability (ink‐jet printing and roll‐to‐roll process) 6, 24–26…”

New semiconducting copolymers, poly((TIPS‐ADT)‐(4,4′‐didodecyl‐2,2′‐bithiophene)) (PTADT2) and poly((TIPS‐ADT)‐(2,2′‐(4,4′‐didodecyl‐2,2′‐bithiophene)dithiophene)) (PTADT4), produced by incorporating 5,11‐bis(triisopropylsilylethynyl) anthra[2,3‐b:7,6‐b']dithiophene (TIPS‐ADT) and alkyl‐thiophene derivatives were synthesized via Stille coupling polymerization. The optical, electrochemical, structural, field‐effect transistor, and solar cell properties of the polymers were investigated. The polymers showed good solubility at room temperature in common organic solvents due to their abundant side groups including TIPS and dodecyl side chains. Both polymers showed very broad UV absorption spectra covering the spectral range from 300 to 750 nm as a result of the combination of the different absorption ranges of the TIPS‐ADT unit (short wavelength region) and thiophene derivatives (long wavelength region). The FET device fabricated using PTADT4 containing additional unsubstituted thiophene rings as a spacer between TIPS‐ADT and thiophene derivatives showed a higher hole mobility (5.7 × 10−4 cm2/V s) than the PTADT2 device (2.8 × 10−5 cm2/V s), due to the improved intermolecular ordering caused by the reduced steric hindrance between bulky side chain groups. In addition, the PTADT4:(6,6)‐phenyl‐C70‐butyric acid methyl ester (PC70BM) device showed an enhanced power conversion efficiency (PCE) of 1.30% compared with the PTADT2:PC70BM device (PCE of 0.55%) under AM 1.5G irradiation (100 mW/cm2). © 2012 Wiley Periodicals, Inc.
