Described herein are methods, compositions and articles of manufacture involving neutral conjugated polymers including methods for synthesis of neutral conjugated water-soluble polymers with linkers along the polymer main chain structure and terminal end capping units. Such polymers may serve in the fabrication of novel optoelectronic devices and in the development of highly efficient biosensors. The invention further relates to the application of these polymers in assay methods.

An organic electronic material that includes a charge transporting polymer which has a branched structure and has a structural unit having a structure represented by Formula (1).

A temperature integrity sensor or more precisely a temperature continuity sensor of a product which needs to be kept at a temperature below its degradation temperature, is provided. The product includes a refrigerated or frozen edible product; a pharmaceutical product such as a vaccine, or an antibiotic; or a biological-medical product such as a sample of a body fluid or tissue, or an organ. The sensor is based on RFID technology, in particular passive RFID technology.

A curable resin composition contains a polycarbonate resin and a styrenic monomer, the polycarbonate resin comprising a terminal structure that has an unsaturated group represented by the following Formula (1): ##STR00001## and a constitutional unit represented by the following Formula (2): ##STR00002##
