  Selective Transition Enhancement in a g‐Engineered Diradical

  摘要：

  A diradical with engineered g‐asymmetry was synthesized by grafting a nitroxide radical onto the [Y(Pc)2]˙ radical platform. Various spectroscopic techniques and computational studies revealed that the electronic structures of the two spin systems remained minimally affected within the diradical system. Fluid‐solution Electron Paramagnetic Resonance (EPR) experiments revealed a weak exchange coupling with |J| ~ 0.014 cm‐1, subsequently rationalized by CAS‐SCF calculations. Frozen solution continuous‐wave (CW) EPR experiments showed a complicated and power‐dependent spectrum that eluded analysis using the point‐dipole model. Pulse EPR manipulations with varying microwave powers, or under varying magnetic fields, demonstrated that different resonances could be selectively enhanced or suppressed, based on their different tipping angles. In particular, Field‐Swept Echo‐Detected (FSED) spectra revealed absorptions of MW power‐dependent intensities, while Field‐Swept Spin Nutation (FSSN) experiments revealed two distinct Rabi frequencies. This study introduces a methodology to synthesize and characterize g‐asymmetric two‐spin systems, of interest in the implementation of spin‐based CNOT gates.
