Résumé

Hybrid Au(I) compounds exhibit a large domain of applications such as electronic devices, contrast agents, sensors or photocatalysts. These applications are related to the ability of gold(I) to form aurophilic interactions implying self-assembly and luminescence.[1] Among them, gold(I) thiolates are an important class of materials due to the high affinity of gold for sulfur atoms that can generate oligomers or polymers. Depending on the organic substituent of the thiolate, different structures can be obtained: lamellar, helicoidal (Figure a) or cyclic. Recently, a series of gold(I)-thiophenolate-based coordination polymers have shown a thermally induced phase change in the solid state (Figure b and c). The transition from an amorphous phase to a crystalline one is associated with the modification of the photophysical properties (luminescence) to generate a switch of the emission.[2] These photophysical properties are studied in solid-state (Figure d) and coupled with DFT calculations. Tuning the synthesis of gold(I)-thiophenolate allows the formation of luminescent, crystalline and flexible fibers which can generate a composite material mixing gold nanoparticles and crystalline fibers by calcination. This study shows the great potential of gold thiolates as phosphorescent hybrid materials and as precursors for the formation of multifunctional nanocomposites coupling plasmonic and luminescence in electronic devices or photocatalysis.
