摘要： Methods and compositions are provided that include a multichromophore and/or multichromophore complex for identifying a target biomolecule. A sensor biomolecule, for example, an antibody can be covalently linked to the multichromophore. Additionally, a signaling chromophore can be covalently linked to the multichromophore. The arrangement is such that the signaling chromophore is capable of receiving energy from the multichromophore upon excitation of the multichromophore. Since the sensor biomolecule is capable of interacting with the target biomolecule, the multichromophore and/or multichromophore complex can provide enhanced detection signals for a target biomolecule.

摘要： A method of identifying a target analyte in which a sample containing a light-emitting marker configured to bind to the target analyte is irradiated and emission from the light-emitting marker is detected. The light-emitting marker comprises a light-emitting material comprising a group of formula (I): X is one of N and B and Y is the other of N and B; Ar1 and Ar2 independently are an unsubstituted or substituted an aromatic or heteroaromatic group which is unsubstituted or substituted with one or more substituents. Ar1 and Ar2 bound to the same X group may be linked by a direct bond or a divalent group. The group of formula (I) may be a repeat unit of a light-emitting polymer. The light-emitting marker may be used in flow cytometry.

摘要： A novel polyfluorene-based ionomer, an anion exchange membrane, a method for preparing the polyfluorene-based ionomer, and a method for fabricating the anion exchange membrane are proposed. The polyfluorene-based ionomer contains no aryl ether bonds in the polymer backbone and includes piperidinium groups incorporated into the repeating units. The anion exchange membrane is fabricated from the polyfluorene-based ionomer. The anion exchange membrane has good thermal and chemical stability, excellent mechanical properties, and high ion conductivity. Due to these advantages, the anion exchange membrane can be applied as a membrane for an alkaline fuel cell and to a binder for an alkaline fuel cell or water electrolysis.
