Synthesis and Molecular Properties of Tricyclic Biselenophene-Based Derivatives with Nitrogen, Silicon, Germanium, Vinylidene, and Ethylene Bridges
摘要:
A new class of biselenophene-based materials including an sp(3)-silicon-bridged diselenosilole (DSS), an sp(3)-germanium-bridged diselenogermole (DSG), and an sp(3)-nitrogen-bridged diselenopyrrole (DSP) as well as an sp(2)-vinylidene-bridged dicyanodiselenofulvene (CDSF), a diacetylenediselenofulvene (ADSF), and a dioctylethylene-bridged benzodiselenophene (BDS) have been successfully synthesized and characterized. The bridging moieties play an important role in determining the optical and electrochemical properties. The six brominated derivatives are ready to construct various biselenophene-based conjugated materials with tunable properties for organic photovoltaics and field effect transistors.

The inventions disclosed and described herein relate to new and efficient generic methods for making a wide variety of compounds having HAr - Z - Har tricyclic cores, wherein HAr is an optionally substituted five or six membered heteroaryl ring, and Hal is a halogen, and Z is a bridging radical, such as S, Se, NR5, C(O), C(O)C(O), Si(R5)2, SO, SO2, PR5, BR5, C(R5)2 or P(O)R5 and both HAr are covalently bound to one another. The synthetic methods employ a "Base-Catalyzed Halogen Dance" reaction to prepare a metallated compound comprising a five or six membered heteroaryl ring comprising a halogen atom, and then oxidatively coupling the reactive intermediate compound. The compounds of Formula (II) and/or oligomer or polymers comprising repeat units having Formula (II) can be useful for making semi-conducting materials, and/or electronic devices comprising those materials. Acyl compounds can be prepared. Heteroarylene substituents can be used. The tricyclic core can be coupled to itself. The Z group also can be strong electron-withdrawing groups such as C=C(CN)2 or [C=C(CN)2]2. Organic electronic devices can be made including field-effect transistors.
