Embodiments in accordance with the present invention encompass compositions encompassing a latent catalyst and a thermal or photoactivator along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is heated to a temperature from 50° C. to 100° C. or higher to form a substantially transparent film. Alternatively the compositions of this invention also undergo polymerization when subjected to suitable radiation. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. The compositions of this invention further comprises inorganic nanoparticles which form transparent films and further increases the refractive indices of the compositions. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.

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.
