| Research Abstract |
Boron-chelating bithiophene derivatives containing olefinic and acetylenic spacers have synthesized in the research and development of n-type organic semiconductors. These compounds have a quadrupolar structure, in which two positive charges are delocalized on the pi-conjugated system and two negative charges are localized on each boron atom. The olefinic spacers effectively reduce the on-site Coulomb repulsion on the pi-conjugated system according to the electrochemical experiments and hydrolytic analysis. In the crystals, these molecules are stacked into a molecular column, which is assembled to form a layer-by-layer structure. The n-type semiconducting properties of the new compounds are under study.
