Next it was tested, whether the red azolium salt 8•HBr and the previously synthesized green 9•HBr are suitable for the synthesis of a wide range of NHC-metal complexes (scheme 2). Green fluorescent metal complexes with [(NHC)ML] with ML= AuCl, RhCl(cod), IrCl(cod) and Pd(allyl)Cl and red fluorescent metal complexes [(NHC)ML] with ML= CuBr, AuCl, RhCl(cod), IrCl(cod) and Pd(allyl)Cl were obtained using the weak base approach. The red meso-aryl Bodipy turns out to be highly stable towards the basic reaction conditions and the same holds true for the green meso-alkyl Bodipy. In stark contrast, the red meso-alkyl Bodipy is highly sensitive towards the basic reagents used in metal complex synthesis and not suitable for the synthesis of NHC-metal complexes. The fluorescence properties of the respective red and green metal complexes [(NHC)ML] with ML= AuCl, Pd(allyl)Cl, RhCl(cod) and IrCl(cod) are identical, since the distance metal-bodipy is far too large to exert any significant influence on the fluorophore and for the same reason the properties of the metal complexes are not influenced by the nature of the fluorophore. The fluorophores can be considered as remote labels not affecting the metal to any significant degree. The stability of a palladium-pyridine complexes tagged with a related spiro-Bodipy in an organometallic setting was previously demonstrated by Goldsmith et al..
