Outline of Final Research Achievements

Heavy element-bridged π-conjugated systems exhibit interesting functionalities such as carrier-transporting and highly emissive properties, arising from the electronic and quantum effects of the element. In this study, we prepared new heavy element-bridged π-conjugated compounds, such as bridged bithiophene, bibenzofuran, and bipyridyl and investigated their electronic states, and physical and chemical properties. These systems were introduced to integrated systems and polymers to provide optoelectronic materials. In addition, caged polygermasesquioxane, ethenylenediantimony, and Si-π alternating polymers were prepared as new element blocks and their functionalities such as phosphorescent properties were explored.
