    Abstract: Conjugated polymer-based organic field-effect transistors have garnered attention since the solution processability of the semiconductor material raises the possibility of lower device fabrication costs, and considerable progress has been made on achieving high mobility systems. Further improvements in charge carrier mobility while using non-specialized deposition techniques and minimizing the volume of semiconductor used in the fabrication process are important considerations for practical implementation. Here, a method of fabricating devices is disclosed that uses a technique (for example, a scalable blade-coating technique) to cast polymer thin film devices from blend solutions with one component being the polymer semiconductor and the other being a commodity polymer. Even when mixing the semiconducting polymer with 90% polystyrene by weight, an average mobility of 2.7±0.4 cm2 V−1 s−1 can be obtained.

    Abstract: Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor polynucleotide complementary to the target polynucleotide. The sensor polynucleotide comprises a signaling chromophore to receive energy from the excited multichromophore and increase emission in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.

    Abstract: This invention relates to an aggregation sensor useful for the detection and analysis of aggregants in a sample, and methods, articles and compositions relating to such a sensor. The sensor comprises first and second optically active units, where energy may be transferred from an excited state of the first optically active unit to the second optically active unit. The second optically active unit is present in a lesser amount, but its relative concentration is increased upon aggregation, increasing its absorption of energy from the first optically active units. This increase in energy transfer can be detected in variety of formats to produce an aggregation sensing system for various aggregants, including for quantitation. Other variations of the inventions are described further herein.

    Abstract: The present disclosure demonstrates that the introduction of electron deficient fullerene acceptors into thin films comprised of the high-mobility semiconducting polymers suppresses an undesirable “double-slope” in the current-voltage characteristics, improves operational stability, and changes ambipolar transport to unipolar transport. Examination of a variety of high μ polymers shows general applicability. The present disclosure also shows that instability is further reduced by tuning the relative electron affinity of the polymer and fullerene by creating blends containing different fullerene derivatives and semiconductor polymers. One can obtain hole μ values up to 5.6 cm2 V−1 s−1 that are remarkably stable over multiple bias-sweeping cycles. The results provide a simple, solution-processable route to dictate transport properties and improve semiconductor performance in systems that display similar non-idealities.
