Water-soluble photoactive polymers, included polymer tandem dyes, as described as well as methods for their preparation and use. The photoactive polymers can be prepared by direct modification of core polymers (e.g., violet excitable polymers) with dyes or other functional groups. Methods of detecting analytes using the polymers are also described.

Described herein are polyphenylene fibers. The polyphenylene fibers have one or more polyphenylene polymers. The polyphenylene fibers can further include one or more poly(aryl ether sulfone) polymers. In some embodiments, the polyphenylene fibers can have an average diameter that is less than about 1 micron. The polyphenylene fibers can have desirable mechanical properties. Also described herein are methods for forming polyphenylene fibers. In some embodiments, the fibers can be fabricated using specifically engineered polymer solutions in conjunctions with adapted force spinning techniques.

This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color. The electroluminescent spectrum of the conjugated polymer in the present application covers the whole visible light emission area and is close to the pure white light emission, by which the conjugated polymer could be used as a material used in light-emitting layer to prepare the organic electroluminescent devices.
