Abstract: A polyoxymethylene-based all-solid-state polymer electrolyte prepared by in-situ ring-opening polymerization is used in forming an all-solid-state secondary lithium battery. A trioxymethylene monomer, an additive and lithium salt initiates in-situ ring-opening polymerization on a porous support material through a catalyst to form the all-solid-state polymer electrolyte, which has a thickness of 10 ?m-800 ?m, an ionic conductivity of 4×10?5 S/cm—8×10?3 S/cm at room temperature and an electrochemical window not lower than 4.2 V.

Abstract: An m×n fan out device for receiving at least m=2 laser beams of different wavelengths and dividing the power of each laser beam into at least two other laser beams directed to at least one of n exit ports of the fan out device is disclosed.

Abstract: The present invention relates to a novel process of preparing branched polymers by cyclotrimerization and branched organic materials containing triaroylbenzene moieties as base structural unit. The polymerization is a simple one-pot reaction, strictly regioselective and highly functionality-tolerant giving oligomeric and polymeric polymers with high degree of branching (up to 100%) in high yields (up to 99%). The polymers are processible, easily film-forming, transformable (curable) into thermosets by heat or irradiation, and readily crosslinkable by UV irradiation to give patterns with nanometer resolution. The polymers of the present invention can be blend with a variety of macromolecules for general use. The polymers can be metallified utilizing organometallic acetylene as building blocks and ceramization of the patterns of the obtained polymers afford ferromagnetic ceramic patterns with high resolution.

Abstract: The present invention relates to devices for detecting the presence or absence of a target molecule or substance, compounds which may be employed in such devices and methods of using such compounds. In some embodiments, the compounds are conjugated polyenes.

Abstract: A diacetylene-based branched (co)polymer of the general formula (I): where R1 and R2 represent any organic group and R3, R4, and R5 represent either protons from unreacted acetylene moieties or other organic groups from end-capping and/or functionalization agents, with m?0 and n?1, which is processable, exhibit photo- and electroluminescence, show high photo refractivity, is thermal and irradiative curable to heat and solvent resistant materials. The present invention can be blend with a variety of macromolecules for general use. The polymer can be metallified by reacting with organometallic complexes and ceramization of the obtained organic-inorganic hybrids afford ferromagnetic materials with high magnetizability.

Abstract: There is disclosed a liquid crystalline polyacetylene having a repeat structure of the formula where spa is a spacer group and mes is a mesogenic substituent.

Abstract: A method for limiting the transmission of light through a material is disclosed. In the method, a layer composed of a hyperbranched polymer formed via a copolycyclotrimerization reaction is interposed between a light source and the material. Also provided is a method for emitting light comprising exciting the hyperbranched polymer. In addition, methods for limiting the transmission of light and for emitting light using hyperbranched polymers formed by homopolycyclotrimerization reactions are disclosed. A new class of hyperbranched polymers produced by copolycyclotrimerization is also disclosed.
