Three novel β-diketonato ligands were synthesized containing the fluorene-group as substituent. Rhodium(I) complexes thereof were synthesized as reported in Fluorene-containing β-diketonato ligands and their Rhodium(I) complexes. The 1H and 13C NMR’s of all 6 compounds are reported. Spectroscopic data of concentration variations vs absorbance intensities are given for ligands and rhodium(I) complexes showing that they follow the Beer-Lambert law and extinction coefficients (ԑ) are determined. Fluorescence quantum yields are determined and graphs showing the integrated fluorescent intensities vs absorbance are shown. The electrochemistry data of compounds 1 – 6 are reported for scan at 100 - 500 mV/s scan speeds.
