Photocontrolled Multiple-State Photochromic Benzo[b]phosphole Thieno[3,2-b]phosphole-Containing Alkynylgold(I) Complex via Selective Light Irradiation
The development of photoresponsive systems that show multiple-state photochromism has remained a challenging task. We present an alkynylgold(I) complex that features multiple photoinduced color changes, in which the gold(I) center plays an important role in allowing multiple photochromic reactions.
