        摘要：Electroluminescent materials, involving inorganic semiconductors like Ⅱ-Ⅵ compounds, metallorganic compounds and conjugated polymers,have many advantages in mobile communication and large plane display devices.In the dual emitting devices containing semiconductor nanocrystals and electroluminescent polymers, the emitting wavelength could not only be adjusted by doping or by forming core-shell structure,but also depend upon the content in the system and the applied voltage.The inorganic semiconductors with high-charge transporting abilities could affect the emission efficiency of the polymer emitter.Dual functions can also be achieved with high emission efficiency by benefiting from the photoconduction of the semiconductor nanocrystal and the electroluminescence of the polymer.

        摘要：A new general mechanism of polymerization,reactivation chain polymerization,has been proposed based on the classical chain and step polymerization mechanisms.According the present mechanism,the polymer chain propagation is accomplished by reactivating a nonreactive or dormant chain (Mm) to a reactive species (), which reacts with a monomer (M), leading to formation of a dormant product with higher molecular weight (Mm+1) . Major examples of the reactivation chain polymerization include the oxidative polymerization of aniline and probably other aromatic monomers,living radical polymerization,and biological polymerization for the synthesis of nucleic acids and proteins.
