Abstract: Four conjugated copolymers with a donor/acceptor architecture comprising 4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b′]dithiophene as the donor structural unit and benzo[2,1,3]thiodiazole fragments with varying degrees of fluorination have been synthesized and characterized. It has been shown that the HOMO levels were decreased after the fluorine substitution. The field-effect charge carrier mobility was similar for all polymers with less than an order of magnitude difference between different acceptor units.

Abstract: One or more embodiments of the present invention report here a comparative study of field effect transistors (FETs) fabricated with semiconducting polymer PBT, regioregular semiconducting polymers, PCDTPT and their fluorinated analogue (P2F, PCDTFBT), in the transistor channel. The present invention shows that simple fluorination of PBT and PCDTPT to PCDTFBT leads to air-stability and reliable transistor characteristics. The FETs fabricated from aligned PCDTFBT yielded stable threshold voltages (at zero volt) and a narrow distribution of saturation hole mobilities of 65 cm2 V−1 s−1 (average over 50 independent FET devices). At higher source-drain voltage (higher electric field in the channel) the mobility approaches 100 cm2 V−1 s−1, the highest value for semiconducting polymers reported to date. High mobility is retained over 150 hours in ambient air without any encapsulation layers. The results obtained in one or more embodiments of the invention represent important progress for solution-processed plastic transistors, and provide molecular design guidelines for high-mobility and air-stable conjugated polymers.

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.
