Abstract

The rational design and synthesis of donor–π–acceptor (D–π–A) type tetraphenylsilane (TEPS)-based PAFs (PAF-403, PAF-404, and PAF-405) linked by acetylene bridges are presented. Among them, PAF-405 displays the highest efficiency for visible-light-induced C-3 thiocyanation of indoles (up to 99% yield) with broad substrate scope (15 examples), which could be recycled for five cycles with a slight loss of catalytic activity. A possible structure-performance correlation of TEPS-PAFs is proposed.

四苯基硅烷基多孔芳香骨架上吲哚的高效光催化C-3硫氰化反应。

介绍了乙炔桥联的四苯基硅烷（TEPS）基给π-受体（D-π-A）型paf （PAF-403、PAF-404和PAF-405）的合理设计和合成。其中，PAF-405在可见光诱导下对吲哚的C-3硫氰化反应效率最高（产率高达99%），底物范围广（15例），可循环5次，催化活性损失较小。提出了一种可能的teps - paf结构-性能相关性。
