Abstract

The role of noncovalent interactions is reviewed in the context of stimuli-responsive behaviour of gold(I) and gold-heterometal complexes. These noncovalent interactions are often highly sensitive to physical (thermal, optical, electrical, mechanical, etc.) or chemical (solvents, guests, etc.) stimuli so as to trigger alterations in molecular and crystal structures leading to dynamic changes in macroscopic properties of gold compounds. In this microreview, we summarized some representative examples of gold(I) complexes that exhibit intriguing stimuli-responsive properties such as thermochromic, mechanochromic, vapochromic and solvatochromic luminescence, as well as vapochromism and gas sorption. Stimuli-responsive functional materials with specific properties have potential for various applications including chemical sensors, memories, data storage, security inks and separation technologies.
