Abstract
A new multistimuli-responsive luminescent material, [Cu8I8(4-dpda)(6)](n) (1) (4-dpda=4-(diphenylphosphino)-N,N-dimethylaniline), has been obtained by combining inorganic Cu8I8 clusters and organic ligands 4-dpda, providing a novel in-/organic hybrid approach as an interesting alternative to all-organic approaches. Compound 1 responds well to thermo and mechanical force independently with color change due to the fact that the stimuli affect frontier molecular orbital and molecular packing modes, respectively.
