g-Engineering in Hybrid Rotaxanes To Create AB and AB(2) Electron Spin Systems: EPR Spectroscopic Studies of Weak Interactions between Dissimilar Electron Spin Qubits

摘要

Hybrid [2] rotaxanes and pseudorotaxanes are reported where the magnetic interaction between dissimilar spins is controlled to create AB and AB(2) electron spin systems, allowing independent control of weakly interacting S-1/2 centers.
