20100129757 | SYNTHESIS OF ACYLARYLENES AND HYPERBRANCHED POLY(ACLARYLENE)S BY METAL-FREE CYCLOTRIMERIZATION OF ALKYNES - 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. | 05-27-2010 |
20110171448 | PREPARATION OF HYPERBRANCHED POLY(TRIAZOLE)S BY IN SITU CLICK POLYMERIZATION AND ADHESIVE CONTAINING THE SAME - Provided is a high temperature-resistant metal adhesive containing hyperbranched poly(triazole)s synthesized by in situ azide/alkyne click polymerization. Also provided is a method for preparing the same adhesives by in situ click polymerization of azide and alkyne monomers on metal substrates. The method is optimized to get high adhesive strength at room temperature or elevated temperatures by analyzing the effects of monomer ratio, curing temperature and time, and annealing temperature and time. The hyberbranched poly(triazole)s adhesive has comparable or better temperature resistance compared with known high temperature epoxy metal adhesives, and it is the first high temperature metal adhesive using hyperbranched poly(triazole)s prepared by in situ azide/alkyne click polymerization. | 07-14-2011 |

20130089889 | Aggregation Induced Emission Active Cytophilic Fluorescent Bioprobes for Long-Term Cell Tracking - Fluorescent bioprobes comprising fluorogen formed nanoparticles comprising fluorogens with aggregation-induced emission (ATE) properties, which can be used for long-term cell tracking. The fluorogens are nonemissive in organic solution but become highly emissive when aggregated in aqueous solution. The fluorescent molecules can readily pass through cell membranes, stain only the cell cytoplasm, and form highly emissive nanoaggregates in aqueous media without any obvious cytoxicity in the living cells. Furthermore, the molecules can be retained inside the cells without noticeable leakage to the outside. Therefore, these ATE-based compounds can be used as selective and cell-compatible fluroescent bioprobes for long-term live cell tracking and imaging. | 04-11-2013 |
