摘要:
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.
摘要:
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.

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.
摘要:
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.
