Résumé The PCl3-promoted intramolecular cascade cyclization produced a series of thiophene-fused phospholo[3,2-b]phosphole derivatives, including non-oxidized 2, dioxides 3, and disulfides 4. These derivatives exhibit significantly red-shifted absorptions and fluorescences compared with their benzene-fused analogues. Among the thiophene-fused series, the non-oxidized 2 has the highest fluorescence quantum yield of 0.95. This trend is in contrast to that observed for the benzene analogues, in which a dioxide derivative shows the most intense fluorescence.

摘要 PCl3 促进的分子内级联环化产生了一系列噻吩融合的磷并[3,2-b]磷烯衍生物,包括非氧化物 2、二氧化物 3 和二硫化物 4。与苯融合类似物相比,这些衍生物表现出明显的红移吸收和荧光。在噻吩融合系列中,未氧化的 2 的荧光量子产率最高,达到 0.95。这一趋势与在苯类似物中观察到的趋势相反,在苯类似物中,二氧化物衍生物显示出最强烈的荧光。 补充材料: 本文的补充材料以单独文件形式提供:mmc1.pdf
