Mesyl and Triflyl Functionalized N-Heterocyclic Carbenes as Acceptor Fragments in Luminescent Carbene-Metal-Amide Complexes

Synthetic procedures providing access to mesyl and triflyl functionalized derivatives of 1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene (SIPr) have been provided in detail. New luminescent carbene-metal-amide (CMA) Cu(I) complexes based on acceptor group functionalized SIPr have been prepared. The effect of the LUMO energy in the sulfonyl functionalized N-heterocyclic carbene (NHC) series on the emissive properties of the CMAs has been investigated.
