Abstract: Highly luminescent silver(I) coordination polymers [Ag 2 X 2 (PPh 3 ) 2 (Me 2 pyz)] n (X = I, Br, Cl; Me 2 pyz: 2,5-dimethylpyrazine) were prepared together with copper congeners [Cu 2 X 2 (PPh 3 ) 2 (Me 2 pyz)] n (X = I, Br). All the complexes showed thermally activated delayed fluorescence from the charge-transfer states in the visible region, from blue to red. The isomorphous relationship among the complexes allowed a detailed discussion of the effect of halogenido ligands and crystal packing on their lumin… Show more
