摘要:Conjugated polymer light-emitting electrochemical cell (LEC) is a new type of light -emitting devices, which is composed of a thin polymer film sandwiched between two electrodes. The film is a blend of luminescent polymer and solid electrolyte. Compared with polymer light-emitting diodes, LEC is of the advantages of good stability and low operating voltage-In this paper, the device configuration,operation mechanism of LEC and the recent progress in its study were described.
摘要:Polymer blends with controllable specific -interaction containing multicomponent may exist three physical states, i. e., immiscibility, miscibility and complexation, with increasing the density of specific interaction. In this paper,we discussed the progress in the studies of miscibility and complexation with emphasis on the difference and similarity between miscibility and complexation. That miscibility-complexation transition is a universal phenomenon in the polymer blends with controllable hydrogen -bonding was proposed.
摘要:In this paper,the progress in research for soluble conducting polyaniline (PANI)and the synthesis of water-soluble conducting PANI are reviewed. The research direction of water-soluble PANI is pointed out.

摘要:The chemical reaction principles and application practices in the synthesis of polymeric materials from carbonmonoxide are presented in this paper. Poly ketones, polyesters and poly amides are prepared from olefins, formaldehyde, amides and carbonmonoxide respectively. Hydrogenation of carbonmonxide or synthesis gas produces polymethylene. The research trends and development prospects in the synthesis of macromolecules from carbonmonoxide are also discussed.
