Abstract

Face-on and close configuration of a π-conjugated molecule on an Au cluster generates a strong π–metal coupling between the π and metal orbitals. We successfully synthesized porphyrin-coordinated Au clusters in face-on configuration at the closest distance. The interaction between the Au cluster and porphyrin was investigated by UV-vis-NIR and transient absorption measurement.
