单参考密度泛函理论(DFT)方法的含铜大环配合物的氧化还原电位的计算的适用性得到了证实,通过使用T1诊断沿着与可忽略的自旋污染或波函数不稳定性的验证。当检查cc-pVnZ基组系列的改进对计算的氧化还原电位的影响时,结果容易地收敛在cc-pVTZ水平。的全电子Def 2-TZVPP基组被证明是一个合适的选择时,利用一个cc-pVTZ几何的氧化还原电位的计算基组。表现最好的模型化学被确定为M06/极化连续模型(PCM),因此,一个计划的氧化还原电位计算的铜大环使用M06/CC-pVTZ与PCM溶剂化提出了可靠地再现实验趋势。
Suitability of single-reference density functional theory (DFT) methods for the calculation of redox potentials of copper-containing macrocycle complexes was confirmed by the use of T1 diagnostics along with a verification of negligible spin contamination or wave function instability. When examining the effect of improvement in the cc-pVnZ basis set series on calculated redox potentials, the results readily converged at the cc-pVTZ level. The all-electron Def2-TZVPP basis set is shown to be a suitable choice of a basis set for the calculation of redox potentials when utilizing a cc-pVTZ geometry. The best-performing model chemistries are determined to be the M06/polarizable continuum model (PCM); therefore, a scheme for redox potential calculations of copper macrocycles using either M06/cc-pVTZ with PCM solvation is proposed to reliably reproduce experimental trends.
