by graphitic carbon materials. Herein, we report the bridging coordination behaviour of acenaphthylene to a Pd3 or a Pd4 cluster. A bis-acenaphthylene Pd3 chain cluster and an acenaphthylene-COT Pd4 sheet cluster were isolated, and the μ3-π-coordination mode or the μ4-oxidative π-addition mode of the acenaphthylene ligand in each cluster was elucidated by X-ray structure analysis.
The Pd2-translocation on a tetraene ligand is switchable between the thermodynamic equilibrium state and the photo-stationary state. The Pd7-translocation on a carotene ligand proceeds smoothly under photo-irradiation.
