| Summary: | 碩士 === 淡江大學 === 化學學系碩士班 === 95 === Rigid molecular architectures which consist of a trivalent core and three π-extended arms (so-called star-shaped molecule) are currently attracting considerable attentions because of their potential application in electrooptical material such as organic light-emitting diode(OLED). We introduced a sonochemical Barbier-type reaction which was previously reported by this laboratory to prepare heterocyclic organostannanes and heterocyclic organosilanes. These heterocyclic compounds were applied to synthesize these designed star-shaped molecules by using palladium-catalyzed Hiyama, Stille and Sonogashira cross-coupling reactions. We introduced electron-donating group(OMe) and electron-withdrawing group(CF3) to the outside shell of these star-shaped molecules and measured their physical and chemical properties. The results showed that the observed physical properties of electron-donating group attached star-shaped molecule (benzene as core) exhibited better red-shift performance in thin-film photoluminescence than its electron-withdrawing group attached compound.
