摘要: Silicon-containing -conjugated compounds, especially silacyclopentadienes (siloles), have emerged as a new class of electroactive materials with good electron transport properties in OLEDs. 9,9'-spiro-9-silabifluorene compound well its starting material 2,2'-dibromobiphenyl been synthesized higher yields. Spirosilabifluorene is expected to be an efficient host for the blue-light emitting diodes. 9,9'-spiro-9-silabifluorene, 1,1-dichloro-1-silafluorene, and 1,1-dimethyl-1-silafluorene were characterized by -NMR, UV/Vis photoluminescence spectroscopy.
