A novel carbazole-based gold(I) complex with interesting solid-state, multistimuli-responsive characteristics.

A new carbazole-based mononuclear gold(i) complex was designed and synthesized. The novel luminogen shows significative solid-state reversible mechanochromism, dual-responsive thermochromism and sensitive thin-film vapochromism properties. In addition, we obtained two kinds of crystals of the luminogen that may explain these interesting characteristics.
