    Abstract: Redox reactions that occur at the electrodes of batteries require transport of both ions and electrons to the active centers. Reported is the synthesis of a block copolymer that exhibits simultaneous electronic and ionic conduction. A combination of Grignard metathesis polymerization and click reaction was used successively to synthesize the block copolymer containing regioregular poly(3-hexylthiophene) (P3HT) and poly(ethylene oxide) (PEO) segments. The P3HT-PEO/LiTFSI mixture was then used to make a lithium battery cathode with LiFePO4 as the only other component. All-solid lithium batteries of the cathode described above, a solid electrolyte and a lithium foil as the anode showed capacities within experimental error of the theoretical capacity of the battery. The ability of P3HT-PEO to serve all of the transport and binding functions required in a lithium battery electrode is thus demonstrated.

    Abstract: A resist film (102) made of a chemically amplified resist material including a polymer containing an acid leaving group and a group in which a lactone is replaced with hydrogen in an OH group of phenol is formed on a substrate (101). The resist film (102) is then selectively irradiated with exposure light, thereby performing pattern exposure. After the pattern exposure, the resist film (102) is heated, and then developed, thereby forming a resist pattern (102a) out of the resist film (102).

    Abstract: Described is a direct method for the fabrication of resorcinarene nanocapsules by photopolymerization of compounds of formula (I), such as resorcinarene tetraalkene tetrathiol (RTATT), in the absence of any template or preorganization. Further, by varying the polymerization media, a variety of other polymeric architectures like lattices, fibrous networks, and nanoparticles were obtained. The morphology and structure were characterized by transmission electron microscopy, energy dispersive spectroscopy, scanning electron microscopy, dynamic light scattering, infrared and nuclear magnetic resonance spectroscopy. These morphologically distinct resorcinarene polymeric architectures contain residual thiol and ene functional groups offering potential functionalization opportunities.
