Adjustable electroluminescence: blue-green to red organic light-emitting diodes based on novel poly-non-conjugated oligomers

摘要

Two new polymers, poly-9,10(1,3-bis (4-ethynylphenoxy) propane) anthracene and poly-1,2(tetra-2,5-thienylene-1,2-vinylene) dimethyl-silyslethane, based onconjugated chromophores that are interconnected via non-conjugated spacers, were prepared and characterized in terms oftheir photo- and electroluminescence (PL and EL, respectively)properties in pure films and in solid solutions. The application ofsolid solutions of the two polymers in PVK:PBD (polyvinylcarbazole:2-(4-biphenyl)-5(4-tert-buthyl phenyl)-1,3,4-oxadiazole)matrices as active layers in adjustable blue-green to red OLED ispresented. 1999Elsevier Science S.A.
