The present invention provides a new metal-free cyclotrimerization reaction of alkynes to produce a 1,3,5-triacylarylene or 1,3,5-triacylbenzene. This reaction is catalyzed by secondary amines, is strictly regioselective, highly functionality-tolerant, and the resulting product can be obtained in high yields. This reaction can be further applied for the preparation of novel branched (co)polymers bearing the triacylarylenes as structural units. The preparation of the (co)polymers is carried out as a one-pot single-step reaction procedure, giving branched oligomers and polymers in high yields up to 90%. The produced (co)polymers are also processible, easily film-forming, and thermally stable.

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.

Environment sensor and conjugated polyene for manufacturing environment sensors

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.

Soluble branched triaroylbenzene-based polymer and its synthetic method

The presently described subject matter is directed to water-soluble conjugated polyene compounds that exhibit aggregation induced emission, as well as to water dispersible, fluorescent, polymeric microparticles and/or nanoparticles comprising the water-soluble conjugated polyene compounds. Also provided are methods of making and using the compounds and particles. The described conjugated polyene compounds are useful as bioprobes for the detection biomacromolecules, as well as in the manufacture of sensors.

A process of synthesizing hyperbranched polytriazoles, linear and hyperbranched poly(aroyltriazoles) by Huisgen 1,3-dipolar cycloaddition. The polytriazoles were prepared by A+Bmethod to avoid self-polymerization during monomer preparation and storage. The polymers are light emissive and can be crosslinked to generate well-resolution photopatterns upon UV irradiation. White light emission patterns were observed with fluorescence microscopy. The high molecular weight poly(aroyltriazoles) (up to 26000 Da) are prepared in high yields (up to 92.0%) and with high regioselectivity (the ratio of 1,4- and 1,5-disubstituted 1,2,3-triazole is equal or larger than 9:1). The polycyclomerization is not moisture or oxygen sensitive and therefore, no special precautions are necessary before and during the reaction. All the polymers are processible, easily film-forming, and curable into thermosets by heat or irradiation. The hyperbranched polymers can act as fluorescent adhesive materials with large tensile strength.
