摘要：

The low molecular weight dye [2-methyl-6-[2-(2,3,6,7-tetrahydro-1H, 5H-benzo[ ij]quinolizin-q-yl)ethenyl]-4H-pyran-4-ylidene]-propane dinitrile (MPD) dispersed in an alternating block copolymer containing thiophene vinylene chromophore units and inert oligomethylene spacer units provided bright red luminescent emission centered at 645 nm. The strength of the emission was based, in part, on efficient energy transfer between the copolymer matrix and the dye. The characteristics of an electroluminescent diode based on this blend, and provided also with a hole transport layer and additional carrier transport components, were investigated.
