Article 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.
