This new class of blue-emitting conjugated polymers was prepared via a Suzuki cross-coupling reaction and showed low turn-on voltages in electroluminescent devices as a result of their low ionisation potentials. The photophysical, electrochemical and electroluminescent properties of these materials are discussed. [GRAPHICS] omposites.

PVP is alkaline, and thus capable of catalyzing the sol-gel process to generate an inorganic shell. Furthermore, pre-formed nanoparticles can also be absorbed by the shell through specific interactions. The PS core is not infiltrative during synthesis, and hollow rings can be derived after the polymer templates are removed. [GRAPHICS] b 收起
