Luminescent and sustainable d coinage metal thiolate coordination polymers for high-temperature optical sensing.

The d coinage metal coordination polymers (CPs) are known to display photophysical properties which can be tuned depending on the functionality of the ligand. Three new CPs made of d coinage metals and methyl thiosalicylate, [M(-SPhCOMe)] (M = Cu, Ag, Au), are reported. They are all constructed from one-dimensional metal-sulfur networks, in which Cu and Ag are three-coordinated to sulfur atoms, whereas Au is only two-coordinated.
