Anisotropic d10 Coinage Metal Organic Chalcogenolate Coordination Polymers for Optoelectronic Technologie

Hybrid materials with chalcogenolate ligands (ER = SR, SeR, TeR) and d10 coinage metals (M(I) = Cu, Ag and Au) are known for a long time in the domains of biology and pharmaceutics. Indeed, copper-thiolates are present in most of the living organisms as metalloproteins, silver-thiolates are recognized for their anti-bacterial activity and some gold-thiolates, as the Myochrysine, have been used as antiarthritic drugs. Today, the d10 coinage Metal Organic Chalcogenolates (MOCs) are gaining a growing relevance in materials science for their semiconductivity and photoluminescence properties. The photoemission of these compounds is attributed to the presence of d10 coinage metals and their ability to display metallophilic interactions. In this presentation, we will show the possibility to tune the dimensionality of the MOC structure as anisotropic 1D or 2D structures and as 3D networks and the resulting photophysical and electronic properties (Fig. 1). Thus, some MOCs exhibit high quantum yield (~70 %) in the solid state, some have intrinsic triple emission associated with luminescence thermochromism allowing optical temperature sensing and some behave as semi-conducting materials with great potentials for thermoelectricity. In addition, MOCs can be shaped as fibers and glasses, and can exhibit phase change behaviors allowing applications in sustainable memory devices.
