제목 Synthesis and Electroluminescent Properties of Copolymers Based on Fluorene and silole
초록 Polyfluorenes (PFs) have emerged as emitting materials suitable for use in PLEDs because of their highly efficient photoluminescence (PL) and electroluminescence (EL), their thermal and oxidative stability, and their good solubility.
Siloles or silacyclopentadienes are a group of five-membered silacyclics that possess a unique low-lying LUMO level associated with the o*-ð* conjugation arising from the interaction between the o* orbital of two exocyclic o bonds on the silicon atom and the ð*orbital of the butadiene moiety. Therefore, five-membered silole compounds have shown to be excellent electron transporting materials in OLEDs.
In this work, a novel series of soluble conjugated random and alternating copolymers
(PHF-BPS) derived from 9,9-dihexylfluorene (HF) and 1,1-diphenyl-3,4-diphenyl-2,5-bis(2-pyridyl)silole (BPS) were synthesized by palladium(0)-catalyzed Suzuki coupling reactions. The optical and electronic properties such as UV absorption, electrochemical properties, photoluminescence, electroluminescence properties of the copolymers were evaluated.
