| 20090043052 | LIVING SYNTHESIS OF CONDUCTING POLYMERS INCLUDING REGIOREGULAR POLYMERS, POLYTHIOPHENES, AND BLOCK COPOLYMERS - Regioregular poly(3-alkylthiophenes) and other polythiophenes can be prepared by living polymerization which have good solubility, processability and environmental stability. The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process. The molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with relatively narrow molecular weight distribution (PDI<1.5) are now readily available. Sequential monomer addition resulted in new block copolymers containing different poly(3-alkylthiophene) segments, which further confirms the “livingness” of this system. Other synthetic methods can be used as well to conduct living polymerization. Blends and electronic devices can be prepared. | 02-12-2009 |

| 20090318626 | Preparation of supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices - The present invention relates to supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices. The invention allows for tuning of the numbers and sequences of donor/acceptor units incorporated in any one crosslinking hydrogen bonding subunit and hence tuning of the interaction strength not only through the amount of crosslinking material incorporated but also through modulation of the strength of the crosslinking interactions. It also allows for the incorporation of more than one type of crosslinking agent in the material allowing for multiple strengths of crosslinking which are each tunable with regard to disruption from solvent, temperature and stress. Hydrogen bond strength between oligomeric chains can be tailored through modification of the numbers and sequences of the donors/acceptors in the oligomers. The oligomers are sequence-specific and will generally only hydrogen-bond to oligomeric chains which are composed of a complementary set of donors/acceptors. The hydrogen bonded motif formed by the interacting oligomers is helical, imparting both chirality and intertwined topology to these interaction points. Because the polymer end units react with their complements through hydrogen bonding, the telechelic polymer(s) incorporating this technology are reversibly able to be processed as the bonds are first broken and then reformed. This has applications in a number of fields such as inkjet inks, adhesives, printing plates and microphase patterning of polymer surfaces. | 12-24-2009 |
