正确预测有机自由基的高自旋稳定性对于设计有机铁磁体仍然是一个重大的挑战。我们开发了一种具有指数(Lmin)的方法,用于预测在受限开壳层Hartree-Fock水平下共轭有机自由基的高自旋稳定性。通过么正变换将非键分子轨道的系数定域化,并利用定域化系数计算了共轭有机自由基的高自旋稳定性Lmin。这种方法可以与伸长方法结合起来处理巨大的高自旋开壳层系统。因此,该方法对有机铁磁体的设计是有用的。© 2015威利期刊公司.
Predicting the high spin stability of organic radicals correctly for designing organic ferromagnets remains a significant challenge. We have developed a method with an index (Lmin) for predicting the high spin stability of conjugated organic radicals at the restricted open‐shell Hartree–Fock level. Unitary transformations were performed for localizing the coefficients of nonbonding molecular orbitals, and subsequently the localized coefficients were used to calculateLminthat indicates the high spin stability of conjugated organic radicals. This method can be combined with the elongation method to treat huge high spin open‐shell systems. Thus, this method is useful for designing organic ferromagnets. © 2015 Wiley Periodicals, Inc.
