Crystal-to-crystal transformation between three CuI coordination polymers and structural evidence for luminescence thermochromism

Article abstract of DOI:10.1002/anie.200704349

Temperature-dependent Cu...Cu distances lead to the luminescence thermochromism of copper(I) coordination polymers with cubane-like Cu ₄X₄ cluster nodes (X = halogen) according to a study on three copper(I) coordination polymers with a bis-thioether ligand (L). The picture shows solid-state luminescence spectra and photographs of the two-dimensional network polymer [Cu₄I₄L₂] _n at 298 and 77 K. (Graph Presented)
