Summary: This study investigates the effects of dipole-dipole interaction on the kinetics of spin-selective reactions using a rigorous kinetic model. The results show that increasing the exchange coupling and reaction rate constants can slow down spin transitions and reaction rates. Additionally, the presence of irreversible reactions in the doublet states affects the evolution of the non-reactive quartet subsystem.

Summary: In this study, we demonstrate the spin modulation of Y2@C79N by host-guest interaction with a carbon nanoring of [12]Cycloparaphenylene ([12]CPP). The adjustable EPR signals of Y2@C79N subset of [12]CPP were observed, indicating the significant effect of host-guest interaction on the spin and paramagnetic property of hooped Y2@C79N. The [12]CPP host induced the orientation of the Y2@C79N guest, which led to enhanced spin-nuclei couplings compared to pristine Y2@C79N.

Summary: Endohedral metallofullerenes (EMFs) display diverse properties due to the combinations between internal metals and outer carbon cages. Yttrium-based metallofullerenes have attracted attention for their luminescence properties. Y3N@C80, for example, exhibits photoluminescence (PL) properties with a small energy gap between the lowest singlet states (S1) and the triplet excited states (T1), allowing reverse intersystem crossing (RISC) and resulting in thermally activated delayed fluorescence (TADF). The PL intensity, lifetime, and quantum yield (QY) of Y3N@C80 depend on the molecular structure and surrounding environment. Modulation of PL properties can be achieved by replacing the yttrium metal inside the carbon cage and modifying the carbon cage externally. This article focuses on the luminescence properties of yttrium-based metallofullerenes, summarizes recent research advances, and predicts their future development.
