Synthesis of Unsubstituted Nonacene
Unsubstituted acenes are intriguing from both experimental and theoretical point of views; however, the preparation and handling of such acenes have been difficult due to their low solubility and high reactivity. Here, unsubstituted nonacene was successfully synthesized in preparative scale.
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.
