Novel ligands for electron-transfer transition-metal complexes

The synthesis of 4, 5-diazospirobifluorene and 4, 5-diazobifluorenylidene, the first two members of a new family of transition metal ligands designed for the study of intramolecular electron and excitation transfer is reported. The description of the synthesis and the H-1-NMR assignments are provided. The UV-VIS and fluorescence spectra of the new ligands, together with a brief discussion of their electronic properties are included.
