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

“…[11] This could be explained by the shortening of some interchain aurophilic interactions down to 3.21(1) Å in HT (Figure S6). [7] This results of the bending of SÀ AuÀ S angles in HT to 133(1)°and 137(1)°, compared to the almost linear one in LT (Figure 2, Table S2). This symmetry lowering can also be seen as a distortion of the double helix from square to parallelogram when seen along the chain axis (Figure S6).…”

“…In addition, we recently reported the ability of some amorphous gold(I)-thiolate, including [Au(SPh)] n and [Au(SEtPh)] n (SEtPh for 2phenylethanethiolate), to form transparent glasses, pointing out the softness of these CPs which is important for devices fabrication. [7] Here, we report an extended work on the [Au(SEtPh)] n amorphous phase which undergoes three thermal PC's below 200 °C, including two successive ones in solid state, with resulting phases having different photoluminescence properties and quantum yields. The three new crystalline [Au(SEtPh)] n CPs have been fully characterized and the reversibility of amorphous-to-crystalline PC has been demonstrated to highlight their great potential for PCRAM.…”

Photoluminescent coordination polymer bulk glasses and laser-induced crystallization

“…16,17 Au + and thiophenolate CP only showed red luminescence at lowtemperature (À180 C) and a transparency of 26% at 850 nm. 18 It is demanded to explore the new luminescent CP/ MOF glasses to meet these criteria.…”

Sterically Invariant Carborane-Based Ligands for the Morphological and Electronic Control of Metal-Organic Chalcogenolate Assemblies

“…The formed structures, more recently referred to as metal-organic chalcogenolate assemblies (MOCHAs, Figure 1a), have shown great promise in the preparation of low-dimensional metal-chalcogenide materials. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] More specifically, some MOCHAs have been synthesized using a biphasic approach from aqueous metal cations (e.g. copper(I) 20 , silver(I) 24 ) layered with chalcogenols (e.g.…”
