“…Thus, this high-energy emission could be assigned to a metal-perturbed intraligand (IL) transition. Similar behavior has been observed before in Au(I) phosphane complexes containing a 4-nitrophenylthiolate ligand [30] and dinuclear neutral thiolate Au(I) complexes with phenylene spacers [31].…”

The photoluminescence of gold thiolate clusters brings about many potential applications, but its origin is still elusive because of its complexity. A strategy in understanding the structure–properties relationship is to study closely related neutral gold thiolate coordination polymers (CPs). Here, a new CP is reported, [Au(m-SPhCO2H)]n. Its structure is lamellar with an inorganic layer made of Au–S–Au–S helical chains, similar to the [Au(p-SPhCO2H)]n analog. An in-depth study of its photophysical properties revealed that it is a bright yellow phosphorescent emitter with a band centered at 615 nm and a quantum yield (QY) of 19% at room temperature and in a solid state. More importantly, a comparison to the para-analog, which has a weak emission, displayed a strong effect of the position of the electron withdrawing group (EWG) on the luminescent properties. In addition, [Au(m-SPhCO2H)]n CPs were mixed with organic polymers to generate transparent and flexible luminescent thin films. The ability to tune the emission position with the appropriate contents makes these nontoxic polymer composites promising materials for lighting devices.

The present article reviews structures, properties, reactivity and applications of transition metal complexes supported by the parent thiophenolate ligand system and various derivatives thereof. This extensive outline of literature published in the last decade covers publications about di‐ and higher nuclear complexes that exhibit bridging thiophenolate functions. The structuring of this contribution is based on the type of ligand involved in the coordination, covering monodentate thiophenolate ligands as well as bi‐ and higher dentate derivatives being acyclic or macrocyclic. An emphasis is set on structures but reactions, reactivity and catalysis, redox chemistry, and other properties of the complexes in review are discussed where appropriate.

Cyclic Solid‐State Multiple Phase Changes with Tuned Photoemission in a Gold Thiolate Coordination Polymer

et al. 2022

The discovery of a universal memory that exhibits fast access speed, high-density storage, and nonvolatility has fuelled research into phase-change materials over the past decades. In spite of the efficiency of the inorganic chalcogenides for phase-change random access memory (PCRAM), they still have some inherent drawbacks, such as high temperature required for phase change and difficulty to control the domain size of the phase change, because of their brittleness. Here we present a Au I -thiolate coordination polymer which undergoes two successive phase changes on application of mild heating (< 200 °C) from amorphous-to-crystal-line1-to-crystalline2 phases. These transitions are reversible upon soft hand grinding. More importantly, each phase exhibits different photoluminescent properties for an efficient optical read-out. We believe that the ability of the Au I -thiolate coordination polymer to have reversible phase changes under soft conditions and at the same time to display distinct optical signals, can pave the way for the next generation of PCRAM.
