Abstract
In this paper, the structural and electronic properties of polythiophene and polyprrrole-based systems have been investigated using first-principles calculations both in periodic and oligomer forms. Of particular interest is the band gap modulation through substitutions and bilayer formation. Specifically, S has been substituted by Se and Te in polythiophene, leading to polyseleophene and polytellurophene, respectively, and N has been substituted by P and As in polypyrrole. The values obtained of the binding energy suggest that all the systems studied can be realized experimentally. Stacking (bilayer formation) of pure polythiophene, polypyrrole and their derivatives leads to linear suppression of the band gap or HOMO-LUMO gap as a function of the stacking. Mixed bilayers, including one formed from polythiophene on top of polypyrrole, have also been considered. Overall, a wide range of band gaps can be achieved through substitutions and stacking. Hybrid (B3LYP) calculations also suggest the same trend in the band gap as PBE calculations. Trends in the binding energy are similar for both periodic and molecular calculations. In addition, Γ-point phonon calculations were performed in order to check the stability of selected systems.

Abstract
Singlet exciton localization in conformationally disordered poly(3-hexylthiophene) (P3HT) is investigated via configuration interaction (singles) calculations of the Pariser-Parr-Pople model. The P3HT structures are generated by molecular dynamics simulations. The lowest-lying excitons are spatially localized, space filling, and nonoverlapping. These define spectroscopic segments or chromophores. The strong conformational disorder in P3HT causes breaks in the pi-conjugation. Depending on the relative values of the disorder-induced localization length and the distances between the pi-conjugation breaks, these breaks sometimes serve to pin the low-lying localized excitons. The exciton confinement also causes a local spectrum of low-lying exciton states. Coulomb-induced intra- or interchain interactions between spectroscopic segments in close spatial proximity can delocalize an exciton across these segments, in principle causing phase coherent transition dipole moments.

Abstract
An approach to the design of electrodes for the production of sensors, which show significant changes to the passage of current in response to the concentration of target protein molecules, is presented. Screen-printed platinum electrodes, modified with two separately applied conducting polymer layers, have been developed as a potential route to forming cheap disposable protein sensors. To achieve a heightened response for the target molecules, an initial layer of polypyrrole was formed on the electrode's surface by electro-deposition. This composite was then employed as a substrate for the subsequent electro-deposition of a relatively thin 'sensing layer' of poly-aminophenylboronic acid. Cyclic voltammetry (CV) of the prepared films revealed an excursion in the current versus potential curve in the anodic phase at approximately 0.0 to +0.2V. It was clearly shown that the introduction of proteins into the CV cell resulted in a measurable decrease in the passage of current in buffered aqueous media. Measured current reductions observed on introducing lysozyme (10ppm) into the test solution were 2.3x10(-6)A for an electrode formed with a poly-aminophenylboronic acid layer on platinum, and 1.75x10(-5)A for a composite electrode formed with poly-aminophenylboronic acid on a polypyrrole coated platinum substrate. The introduction of the competing analytes, dl adrenaline or dopamine, at concentrations typically found in human urine, had little effect on the sensor's response. Additionally, the sensing system was able to maintain a response to added target proteins with as much as 2vol.% urine in the test solution. Using the electrodes in high concentrations of competing physiological analytes, they were able to respond to protein concentrations as low as 0.5ppm in buffered solutions containing urea at a concentration representative of human urine (17,000ppm), which additionally contained glucose (1000ppm).

Abstract
Using a parameter-free, density-functional method that has been developed explicitly for the theoretical treatment of infinite, periodic, isolated, helical polymers we study various polymers related to polythiophene. In particular we discuss how the electronic properties of polythiophene are changed when replacing some of the H atoms by CH3 group, by incorporating vinylene bridges into the backbone, or when replacing some or all the CH units of the backbone by N atoms. We observe the weakest effects for the methyl-substitution and the strongest for the N-incorporation. The latter leads to an overall downward shift of all bands, but in contrast to the case for polyacetylene, the unrelaxed compound with N atoms does not have N lone-pair orbitals as the highest occupied ones. Instead these occur at somewhat deeper energies. When comparing the aromatic and quinoid forms we found for the pure compound as well as for the methyl-containing one that the gap closes when passing from the one to the other form which was not found for any of the other materials of the present study. Moreover, the energy of the HOMO was found to depend stronger on the bond-length alternation than the energy of the LUMO, ultimately giving that polarons will induce two asymmetrically placed gap states with the energetically lower one appearing deeper in the gap than the other one.

Abstract
Substituents are widely used to modify the properties of conducting polymers. To study substituent effects on energy levels and energy gaps systematically, CH(3)-, OH-, NH(2)-, CN-, and CCH-substituted bithiophenes were examined with density functional theory and NBO analysis. Total charges and pi-electron densities were analyzed separately to examine pi- and sigma-effects. Second-order perturbation theory was used to quantify conjugation in terms of orbital interactions. NBO orbital energies were employed to investigate the effect of alternating donor-acceptor substitution. Substituents in 3- and 4-positions shift HOMO and LUMO levels in parallel and hardly influence HOMO-LUMO gaps. For level shifting the pi-donating and pi-accepting abilities are most important; electronegativity mainly influences the sigma-orbitals and is less crucial in determining energy gaps. Alternating donor-acceptor substitution leads to HOMO and LUMO energies that are average between those of the parent systems and has little effect on energy gaps.
