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

Several complexes of "PtL" 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 [PtL] 1D polymers, while for the MCO anion a red, solvent containing dimeric [Pt(MCO)·DMSO] complex has also been isolated. The interconversion of polymorphs was investigated.
