Abstract
In this paper, a series of light-emitting copper(I) iodide inorganic–organic hybrid clusters has been synthesized, and they are 0D-Cu2I2(fmp)4 (1, fmp = 3-fluoro-5-methyl-pyridine), 0D-Cu2I2(iq)4 (2, iq = isoquinoline), 0D-Cu2I2(ni)4 (3, ni = nicotinonitrile). They are all molecular clusters with Cu2I2 rhomboid dimer core which is the result of steric hindrance of organic ligands. The emissions of these compounds range from green to red in the solid state. The band gaps and emission energies of these compounds could be tuned by selecting different organic ligands. These compounds are solution processable and could be coated onto various substrates as luminescent inorganic–organic hybrid coating materials.
