  • The syntheses of 9,9'-spiro-9-silabifluorene as well as 1,1-dichloro-1-silafluorene and 1,1-dimethyl-1-silafluorene through the formation of 2,2'-dibromobiphenyl have been emphasized with good yields. Their fluorescence spectra are obtained using photoluminescence spectrometer and assumed to be the precursors of the development of polymers.

  • New functionalized siloles have been synthesized and their optical characterizations are investigated. Silole unit has been interested, since silole has a unique optical and electronic properties. Here we report the synthesis of new type of photoluminescent silole. New siloles have been characterized by NMR, FTIR, and UV-vis absorption spectroscopy. Their optical characteristics have been also investigated using photoluminescence spectroscopy. Possible applications such as OLED and chemical sensors will be presented.
