We have studied the carrier transport in poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) field-effect transistors (FETs) at very high field-induced carrier densities (10(15) cm(-2)) using a polymer electrolyte as gate and gate dielectric. At room temperature, we find high current densities, 2 x 10(6) A/cm(2), and high metallic conductivities, 10(4) S/cm, in the FET channel; at 4.2 K, the current density is sustained at 10(7) A/cm(2). Thus, metallic conductivity persists to low temperatures. The carrier mobility in these devices is approximately 3.5 cm(2).V(-1).s(-1) at 297 K, comparable with that found in fully crystalline organic devices.

Beyond the metal-insulator transition in polymer electrolyte gated polymer field-effect transistors.

By comparing the changes in pi-pi* absorption with the transconductance in PEO-LiClO4 electrolyte-gated FETs, we have demonstrated that the high channel currents obtained at low gate voltages result from reversible electrochemical doping of the semiconducting polymer film. At low temperatures, the conductivity of the electrochemically doped poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene), PBTTT-C14, is nonlinear with a crossover from dsigma(T)/dT > 0 to dsigma(T)/dT approximately 0 as a function of the source-drain voltage. High current densities, up to 10(6) A/cm2 at 4.2 K, can be sustained in the electrochemically doped PBTTT-C14 films.

Electrochemical doping in electrolyte-gated polymer transistors.

Conducting and semiconducting polymers are important materials in the development of printed, flexible, large-area electronics such as flat-panel displays and photovoltaic cells. There has been rapid progress in developing conjugated polymers with high transport mobility required for high-performance field-effect transistors (FETs), beginning with mobilities around 10(-4) cm(2) V(-1) s(-1) to a recent report of 1 cm(2) V(-1) s(-1) for poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT). Here, the electrical properties of PBTTT are studied at high charge densities both as the semiconductor layer in FETs and in electrochemically doped films to determine the transport mechanism. We show that data obtained using a wide range of parameters (temperature, gate-induced carrier density, source-drain voltage and doping level) scale onto the universal curve predicted for transport in the Luttinger liquid description of the one-dimensional 'metal'.

We have demonstrated a novel sensing strategy employing single-stranded probe DNA, unmodified gold nanoparticles, and a positively charged, water-soluble conjugated polyelectrolyte to detect a broad range of targets including nucleic acid (DNA) sequences, proteins, small molecules, and inorganic ions. This nearly "universal" biosensor approach is based on the observation that, while the conjugated polyelectrolyte specifically inhibits the ability of single-stranded DNA to prevent the aggregation of gold-nanoparticles, no such inhibition is observed with double-stranded or otherwise "folded" DNA structures. Colorimetric assays employing this mechanism for the detection of hybridization are sensitive and convenient--picomolar concentrations of target DNA are readily detected with the naked eye, and the sensor works even when challenged with complex sample matrices such as blood serum. Likewise, by employing the binding-induced folding or association of aptamers we have generalized the approach to the specific and convenient detection of proteins, small molecules, and inorganic ions. Finally, this new biosensor approach is quite straightforward and can be completed in minutes without significant equipment or training overhead.

Abbiamo dimostrato un romanzo sensing strategia impiegando single-stranded DNA sonda, non modificate le nanoparticelle d&#39;oro e un polielettrolita coniugato caricato positivamente, solubile in acqua per rilevare un&#39;ampia gamma di obiettivi tra cui sequenze di acidi nucleici (DNA), proteine, piccole molecole e ioni inorganici. Questo approccio quasi &quot;universale&quot; biosensore &egrave; basato sull&#39;osservazione che, mentre il polielettrolita coniugato in particolare inibisce la capacit&agrave; del DNA single-stranded per impedire l&#39;aggregazione delle nanoparticelle di oro, nessun tale inibizione &egrave; osservato con strutture di DNA &quot;piegati&quot; double-stranded o altrimenti. Dosaggi colorimetrici che impiegano questo meccanismo per la rilevazione di ibridazione sono sensibili e conveniente - picomolar concentrazioni di DNA dell&#39;obiettivo sono prontamente rilevate ad occhio nudo, e il sensore funziona anche quando sfid&ograve; con matrici complesse campione come siero di anima. Allo stesso modo, impiegando l&#39;associazione-indotta pieghevole o associazione di aptameri noi abbiamo generalizzato l&#39;approccio per l&#39;individuazione di specifico e conveniente di proteine, piccole molecole e ioni inorganici.

Hemos demostrado una nueva estrategia de detecci&#xF3;n empleando una sola cadena de ADN de la sonda, no modificados nanopart&#xED;culas de oro, y una carga positiva, soluble en agua polielectrolito conjugado para detectar una amplia gama de objetivos que incluyen &#xE1;cido nucleico (ADN) secuencias, prote&#xED;nas, las mol&#xE9;culas peque&#xF1;as, e inorg&#xE1;nicos iones. Esta casi &#x26;quot;universal&#x26;quot; enfoque biosensor se basa en la observaci&#xF3;n de que, mientras que el polielectrolito conjugado inhibe espec&#xED;ficamente la capacidad de una sola cadena de ADN para evitar la agregaci&#xF3;n de las nanopart&#xED;culas de oro, se observ&#xF3; ninguna inhibici&#xF3;n con tal de doble hebra o de otro modo &#x26;quot;doblado&#x26;quot; estructuras de ADN. Los ensayos colorim&#xE9;tricos que emplean este mecanismo para la detecci&#xF3;n de hibridaci&#xF3;n son sensibles y conveniente - concentraciones picomolares de ADN diana se detectan f&#xE1;cilmente a simple vista, y el sensor funciona incluso cuando es desafiado con matrices de muestras complejas tales como suero sangu&#xED;neo. Asimismo, empleando el plegado de uni&#xF3;n inducida o asociaci&#xF3;n de apt&#xE1;meros se ha generalizado el enfoque para la detecci&#xF3;n espec&#xED;fica y conveniente de las prote&#xED;nas, mol&#xE9;culas peque&#xF1;as, y los iones inorg&#xE1;nicos. Por &#xFA;ltimo, este enfoque nuevo biosensor es bastante sencillo y se puede completar en cuesti&#xF3;n de minutos sin necesidad de equipos importantes o gastos de formaci&#xF3;n.

Split-gate organic field effect transistors: control over charge injection and transport.

Optoelectronic gate dielectrics for high brightness and high-efficiency light-emitting transistors.

A family of four new DA polymers, in which the acceptor moiety benzobisthiadiazole was paired with four different donor moieties, has been synthesized. Surpri-singly, all members of the family exhibit balanced ambipolar behavior, despite polymer to polymer mobilities varying from 10(-4) cm(2) V(-1) s(-1) to 10(-1) cm(2) V(-1) s(-1). Applications in single component CMOS integrated circuits are envisioned.

Ambipolarity in benzobisthiadiazole-based donor-acceptor conjugated polymers.

We have studied the electronic, physical, and transistor properties of a family of donor-acceptor polymers consisting of diketopyrrolopyrrole (DPP) coupled with different accepting companion units in order to determine the effects of donor-acceptor interaction. Using the electronically neutral benzene (B), the weakly accepting benzothiadiazole (BT), and the strongly accepting benzobisthiadiazole (BBT), the accepting strength of the companion unit was systematically modulated. All polymers exhibited excellent transistor performance, with mobilities above 0.1 cm(2)V(-1)s(-1), even exceeding 1 cm(2)V(-1)s(-1) for one of the BBT-containing polymers. We find that the BBT is the strongest acceptor, enabling the BBT-containing polymers to be strongly ambipolar. The BBT moiety also strengthens interchain interactions, which provides higher thermal stability and performance for transistors with BBT-containing polymers as the active layer.

High performance weak donor-acceptor polymers in thin film transistors: effect of the acceptor on electronic properties, ambipolar conductivity, mobility, and thermal stability.

We show that polybis(thienyl)thienodia-thiazolethiophene (PDDTT), a high-performance semiconducting polymer for photodetectors and field-effect transistors, has strong performance dependence on annealing temperature. An unprecedented increase of 3 orders of magnitude is observed in both transistor and photoconductive properties. XRD and AFM evidence points to increased ordering in PDDTT films with annealing. This correlation highlights the importance that order has in determining performance in PDDTT and has possible implications in the design of polymers.

Observations of PDDTT subject to thermal treatment: correlation between performance and order.

The split-gate light emitting field effect transistors (SG-LEFETs) demonstrate a new strategy for ambipolar LEFETs to achieve high brightness and efficiency simultaneously. The SG architecture forces largest quantity of opposite charges on Gate 1 and Gate 2 area to meet in the center of the channel. By actively and independently controlling current injection from separated gate electrodes within transporting channel, high brightness can be obtained in the largest injection current regime with highest efficiency.

High mobility ambipolor organic thin-film transistors based on an ultralow bandgap polymer are presented together with their morphological and optical properties. Hole and electron mobilities of this polymer are of 1.0 cm(2) V(-1) s(-1) and 0.7 cm(2) V(-1) s(-1), respectively. The inverter based on two identical ambipolar transistors exhibits a gain around 35.

High-mobility organic thin film transistors based on a benzobisthiadiazole-containing polymer are presented together with their morphological and optical properties. A very tight packing pattern of "edge-on" orientated polymer chains is observed in their thin films after annealing, and the hole mobility of this polymer is up to 2.5 cm(2) V(-1) s(-1) .

High-hole-mobility field-effect transistors based on co-benzobisthiadiazole-quaterthiophene.

Substituted N-alkyldinaphthocarbazoles were synthesized using a key double Diels-Alder reaction. The angular nature of the dinaphthocarbazole system allows for increased stability of the conjugated system relative to linear analogues. The N-alkyldinaphthocarbazoles were characterized by UV-vis absorption and fluorescence spectroscopy as well as cyclic voltammetry. X-ray structure analysis based on synchrotron X-ray powder diffraction revealed that the N-dodecyl-substituted compound was oriented in an intimate herringbone packing motif, which allowed for p-type mobilities of 0.055 cm(2) V(-1) s(-1) from solution-processed organic field-effect transistors.
