Résumé

Gold-sulphur interaction has a vital importance in nanotechnologies and material chemistry to design functional nanoparticles, self-assembled monolayers or molecular complexes. In this paper, the mixture of only two basic precursors: the chloroauric acid, HAu(III)Cl4, and a thiol molecule, the para-fluorothiophenol (p-HSPhF) are used for the synthesis of gold(I)-thiolate coordination polymers. Under different conditions of synthesis and external stimuli five different functional materials with different states of [Au(I)(p-SPhF)]n can be afforded. These gold-thiolate compounds are (i) red emissive, flexible and crystalline fibers, (ii) composite materials made of these red emissive fibers and gold nanoparticles, (iii) amorphous phase, (iv) transparent glass and (v) amorphous-to-crystalline phase change material associated to a ON/OFF switch of the luminescence. The different functionalities of these materials highlight the great versatility of the gold(I) thiolate coordination polymers with easy synthesis and diverse shaping that may find great potentials as sustainable phosphors, smart textiles, sensors and phase change memories.
