1,1-Dihydrosilafluorenes were synthesized and their electronic and photonic behaviors have been investigated. The synthesized compounds were characterized by 1H and 13C NMR spectroscopy. Absorption and emission spectra for these compounds were obtained by using UV-Visible and fluorescence spectroscopy in solution. Their emission behaviors and quantum yield for these compounds were investigated. Polymers of silafluorene, poly-1,1'-silafluorene, via dehydrocoupling polycondensation using catalysts such as H2PtCl6, Rh(PPh3)3Cl, and Pd(PPh3)4. The polysilafluorenes obtained from various conditions were characterized by gel permeation chromatography(GPC). Comparison of optical behaviors of polysilafluorene by the measurement of fluorescence life time and quantum efficiencies were achieved. Detailed experimental results will be discussed. This research was financially supported by the Ministry of Education, Science Technology (MEST) and National Research Foundation of Korea(NRF) through the Human Resource Training Project for Regional Innovation
