Abstract: Described are compositions comprising amphiphilic polymer nanoparticles, such as DSPE-PEG, encapsulating a photostable agent with aggregation-induced emission (AIE) characteristic. The photostable AIE agents are preferably small organic molecules with tetraphenylethylene moieties. The nanoparticles are synthesized by a modified nanoprecipitation method and the size of the nanoparticles is controlled by varying the loading ratio, the solvent ratio and the tatio of hydrophilic to hydrophobic length of the polymer. The nanoparticles are surface modified with a conjugatable group for covalently linking to at least one targeting moiety, such as antibodies or affibodies to IgG, EGFR and Her2. Methods for immunostaining or imaging or detecting or tracking a live cell, such as cancer cells, using the nanoparticle compositions are described.

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.
