A facile synthesis of nitrogen-containing six-membered benzofuzed phosphacycles has been described. This cyclization reaction triggered by Tf2O provides an expedient protocol of phosphacycles with a simple operation at mild conditions. The preliminary photophysical studies of these novel materials reveal that the fluorescence intensity enhances with the molecular aggregation in the solid state and
已经描述了容易合成含氮的六元苯并氮杂的磷环。由Tf2O触发的这种环化反应提供了一种在温和条件下简单操作的磷环的简便方法。这些新型材料的初步光物理研究表明,荧光强度会随着分子在固态状态下的聚集而增强,并且将空间大的菲基团引入磷杂环化合物可显着提高荧光量子产率。
