由空间要求高的三足四齿配体HIPT 3 tren支撑的铜（I）络合物与O2反应得到单核铜（II）末端超氧代络合物。进行了光谱（UV/维斯、共振拉曼、ESR和1H-NMR）和DFT研究。O2-结合过程以及对外部底物的反应进行了动力学研究，以证明铜（II）末端超氧配合物的独特行为，这可能是由于HIPT 3 tren配体产生的铜配位球周围存在疏水核而发生的。
Reaction of a copper(I) complex supported by a sterically demanding tripodal tetradentate ligand, HIPT3tren, and O2gave a mononuclear copper(II) end‐on superoxo complex. Spectroscopic (UV/Vis, resonance Raman, ESR, and1H‐NMR) and DFT studies have been performed. The O2‐binding process as well as the reaction toward external substrates have been investigated kinetically to demonstrate the unique behavior of the copper(II) end‐on superoxo complex, which may occur as a result of the existence of the hydrophobic core around the copper coordination sphere created by the HIPT3tren ligand.
