Solid-state luminescence switching of platinum(ii) dithiooxamide complexes in the presence of hydrogen halide and amine gases

Abstract

In the solid state, a non-luminescent platinum(ii) dithiooxamide species adsorbs gaseous HCl, yielding a tight ion pair species which exhibits photoluminescence; the process is quantitatively reversed on heating or by exposing the sample to ammonia vapors.
