“…The conjugated polymers with extending π-conjugated electron systems such as polyaniline, polythiophene, polypyrrole, and their derivatives have shown great promises due to their high absorption coefficients in the visible part of the spectrum, high mobility of charge carriers, and excellent stability [7]. In general, they are also efficient electron donors and good hole transporters upon visible light excitation [8].…”

In this study, polythiophene-TiO 2 nanotube films (PTh/TNT) were successfully prepared by a two-step electrochemical process of anodizaton and electropolymerization, in which a highly-ordered TiO 2 nanotube (TNT) film was anodized at a low-voltage with post calcination first and then the prepared TNT film was deposited with a polythiophene layer by electropolymerization in the BFEE electrolyte. The morphology and structures of PTh/TNT composites were examined by FESEM, EDX, XRD, and XPS methods. XPS spectra of PTh/TNT composites indicate the strong interaction between S sites of polymer backbone and TiO 2 nanotubes, in which electron transfer from polythiophene to titania takes place. UV-vis DRS analysis shows that these composites have a strong photoresponse in the visible region at 500 nm. The prepared PTh/TNT films revealed significant activity for 2,3-DCP degradation under visible light irradiation and also sunlight irradiation, in which the PTh3/TNT film achieved the best performance. On the other hand, this study also confirmed that the sidechains of polythiophene could influence its photocatalytic activity significantly in an order from high to low as poly3-methylthiophene ≈ polythiophene > polythiophenecarboxylic acid > poly3-hexylthiophene. The results may provide useful information to further develop This is the Pre-Published Version.2 some effective polymer-semiconductor catalysts for pollutant degradation under sunlight irradiation for water and wastewater treatment.

“…4 The advantages of polymers over conventional inorganic semiconductors are their relatively low cost, suitability for both large areas and nanoscale applications, 5 mechanical flexibility, and most importantly, the potential for printable electronic circuits for integrated plastic electronics. 6 The use of conjugated polymers 7 for ionizing radiation detection is likewise expected to offer several advantages in comparison to silicon, which is the most commonly used semiconductor for high fluence x-ray detection, e.g., at synchrotron sources or for medical dosimetry.…”

The authors report the first direct detection of x-ray induced photocurrents in thick films ͑up to 20 m͒ of conjugated polymers. Schottky-based "sandwich" structures were fabricated from layers of either poly͓1-methoxy-4-͑2-ethylhexyloxy͒-phenylenevinylene͔ ͑MEH-PPV͒ or poly͑9,9-dioctylfluorene͒ ͑PFO͒ on indium tin oxide substrates using a top contact of aluminum. Good rectification was achieved from the Al-polymer contact, with a reverse bias leakage current density as low as 4 nA/ cm 2 at an electric field strength of 25 kV/ cm. Irradiation with x-rays from a 50 kV x-ray tube produced a linear increase in photocurrent over a dose rate range from 4 to 18 mGy/ s. The observed x-ray sensitivities of 240 nC/ mGy/ cm 3 for MEH-PPV and 480 nC/ mGy/ cm 3 for PFO structures are comparable to that reported for Si devices. A response time of Ͻ150 ms to pulsed x-ray irradiation was measured with no evidence of long-lived current transients. Conjugated polymers offer the advantage of easy coatability over large areas and on curved surfaces. Their low average atomic number provides tissue-equivalent dosimetric response, with many potential applications including medical x-ray and synchrotron photon detection.

“…proton conductors for fuel cell membranes [97] and the Li + conductors [98,99] for batteries, where the aim is to combine high protonic or ion transport with sufficient mechanical properties and stability. Undoped conjugated polymers are semiconducting, they can be doped for conductivity and they have interesting electrical and optical properties [47,[100][101][102]. Due to the rigidity of the conjugated chains, there is a tendency for aggregation, which can lead to infusibility and poor solubility.…”
