Shortwave infrared luminescent Pt-nanowires: a mechanistic study of emission in solution and in the solid state.

ABSTRACT: Several complexes of "PtL₂" composition containing two cyanoxime anions - 2-oximino-2-cyano-N-piperidineacetamide (PiPCO^-) and 2-oximino-2-cyano-N-morpholylacetamide (MCO^-) - have been obtained and characterized both in solution and in the solid state. Complexes exist as two distinct polymorphs: monomeric yellow complexes and dark-green [PtL₂]_n 1D polymers, while for the MCO^- anion a red, solvent containing dimeric [Pt(MCO)₂·DMSO]₂ complex has also been isolated. The interconversion of polymorphs was investigated. The monomeric PtL₂ units are arranged into anisotropic extended solid [PtL₂]_n polymers with the help of PtPt metallophilic interactions.
