| Abstract | The caffeine-derived N-heterocyclic carbene (NHC) complex [Pt II(CN)(NHC)Cl] (CN = 2-phenylpyridine), 4 has the opposite stereochemistry and a shorter Pt-Ccarbene bond compared to that of an analogous benzimidazole-derived N,N-heterocyclic carbene (NNHC) Pt complex 2. These suggest a lower trans influence of pyridyl N compared to cyclometallated carbon and an increased Pt-NHC π-backbonding because of decreased π-donation resulting from conjugation to the electron deficient pyrimidine of caffeine. Complex 4 has a lower emission quantum yield (Φ) and is blue-shifted into the green region of the visible spectrum relative to non-carbene Pt(ii) cyclometalated complex 5. © 2011 The Royal Society of Chemistry. |
