本文报导硅胶上固载酞菁铜的电子自旋共振研究结果,通过理论分析和波谱测量得到~(63,65)Cu和~(14)N核超精细耦合常数。电子成键参数计算指出Cu和N原子之间存在有平面外π键,它和平面内σ键一样对决定固载化酞菁铜催化剂的性质起重要作用。
In this paper, the results of electron spin resonance of copper phthalocyanine supported on silica gel were reported. The hyperfine coupling constants of ~ (63,65) Cu and ~ (14) N nuclei were obtained by theoretical analysis and spectroscopic measurements. The calculation of the electronic bonding parameters indicates that there exists an out-of-plane π bond between Cu and N atoms, which plays an important role in determining the properties of the immobilized copper phthalocyanine catalyst as in-plane σ bond.
