Luminescence Properties of Organometallic/Coordination Oligomers and Polymers Containing Diphosphine and Diisocyanide Assembling Ligands: Comparison between Mononuclear Model Complexes and Polymers

摘要

This paper describes the luminescence properties of selected examples of homo- and mixed-bridging ligand-containing organometallic/coordination oligomers and polymers of copper(I), silver(I), palladium(I) and -(0.5), and platinum(0.5). The bridging ligands are the 1,8-diisocyano-p-menthane (dmb) and bis(diphenylphosphino)methane (dppm), -ethane (dppe), -propane (dppp), -butane (dppb), -pentane (dpppen), and -hexane (dpph), as well as bis(diphenyl-phosphino)acetylene (dpa) and bis(dimethylphosphino)methane (dmpm). The comparison between the mononuclear model complexes and the polymers of the emission maxima (λ_(max)) and emission lifetimes (τ_e) will be made, and interpreted by the presence of intrachain interactions and exciton phenomena.
