Fluorescence resonance energy transfer in atomically precise metal nanoclusters by cocrystallization-induced spatial confinement.

ABSTRACT: Understanding the fluorescence resonance energy transfer (FRET) of metal nanoparticles at the atomic level has long been a challenge due to the lack of accurate systems with definite distance and orientation of molecules. Here we present the realization of achieving FRET between two atomically precise copper nanoclusters through cocrystallization-induced spatial confinement. In this study, we demonstrate the establishment of FRET in a cocrystallized Cu₈(p-MBT)₈(PPh₃)₄@Cu₁₀(p-MBT)₁₀(PPh₃)₄ system by exploiting the overlapping spectra between the excitation of the Cu₁₀(p-MBT)₁₀(PPh₃)₄ cluster and the emission of the Cu₈(p-MBT)₈(PPh₃
