Recently, we have explored coordination polymers based on dithioether ligands and (CuI)x. As an extension of our efforts to investigate Cu(I) coordinaion polymers of dithioether ligands, N,N'-bis[2-(tert-butylthio)ethyl]pyromellitic diimide, (L1), N,N'-bis[2-(cyclohexylthio)ethyl]pyromellitic diimide, (L2) were synthesized. Three Cu(I) coordination polymers 1-3 based on the ligands were prepared by self-assembly reaction between CuI and L1, L2. Structural and photophysical studies of CPs 1-3 in solid state are reported. CPs 1-3 are composed of cubane Cu4I4 cluster nodes, emitting red-orange light under UV-irradition. The shift of the emission color of CPs 1-3 in comparison with the yellow color of other Cu4I4 complexes is attributed to halogen- π interactions.
