A new type of push–pull charge transfer complex, viz., a spiro-locked N-heterocycle-fused zinc porphyrin, ZnP-SQ, is shown to undergo excited state charge separation, which is enhanced by axial F− binding to the Zn center.

Synthesis of molecules combining both fullerene and metallocene moieties separated by some spacer is discussed in connection with the possible intramolecular charge transfer. Two new kinds of spacers, =CH-CO- and -Pd-P-, have been introduced by using the corresponding reactions. Reaction of diazoacetyl ferrocene and cymantrene with C60 has been studied in detail and products characterized. 1,1'-Bis (diazoacetyl) ferrocene gave with C60 1:1 adduct to which the ansa-structure has been assigned on the basis of 1H and 13C NMR spectra. Palladium-h2-C60 complex with a bidentate ferrocenyl diphosphine as a ligand has been also prepared.
