Although no direct synergy between SCO and luminescence was observed, the variable temperature solid state UV-Vis absorption spectra of 6-d showed distinct changes as emergence of absorption band in the range of 600 -760 nm coming from the 1 A1 → 1 T1 transition from the Fe(II) LS unit upon cooling from 300 K to 80 K. So, the effective spectral overlap of SCO unit with the fluorophore units appeared to be a key factor for the construction of bifunctional SCOfluorescent complexes.
