A simple synthetic route to poorly available polycyclic systems with a [1,2,5]oxadiazolo-[3,4-b]quinoxaline backbone has been developed, which is based on the sequence of nucleophilic aromatic substitution of hydrogen and the Scholl cross-coupling. According to the data from electrochemical and photophysical measurements, the synthesized compounds can be potentially considered as the narrow-gap (from
已经开发出一种简单的合成路线,可合成具有[1,2,5]恶二唑并-[3,4-b]
喹喔啉主链的难获得的多环体系,该路线基于氢的亲核芳香族取代顺序和Scholl交叉反应耦合。根据电
化学和光物理测量数据,合成的化合物可被视为窄带隙(1.97至2.34 eV)n型有机半导体,其能级可与顶级商用电子半导体相媲美。
