In recent years, photoluminescence polysilole has been a topic of interest because of ther unusual electrical and optical properties. silafluorene is synthesized and evaluated for white O-LED applications. These compounds are of interest as light emissive layers, as they possess relatively low LUMO energy levels while maintaining high HOMO-LUMO optical gaps. Differential scanning calorimetry measurements reveal that these silafluorene compounds have advantages of thermal stability above 300 oC. Organic light-emitting diodes have been fabricated using thermal evaporation technique. They emit blue to bluish-white light with an excellent diode behavior under the forward bias. The synthesis, spectroscopic characterization, and fluorescence quenching efficiencies of silafluorene were reported. 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 both in the solid and colloid state. Our results indicated that both compounds were used as the chemosensor to detect various type of explosives such as (1,3,5-trinitroperhydro -1,3,5-triazine, RDX), nitroaromatics (1,3,5-trinitrotoluene, TNT), and nitrate esters (PETN). The results of detection efficiency showed that both compounds were served as an excellent chemosensors and other silafluorene derivatives were synthesized and their photonic behaviors were investigated. 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.
