采用Gaussian 03程序,在B3 LYP/6- 31 G * 水平上计算了75个多溴代5,10-二氢吩嗪(PBDP)在298.15K和1.013 × 105 Pa下的理想气体状态下的结构和热力学性质.采用等键反应计算了PBDP同系物的标准生成焓(ΔfHθ)和标准生成自由能(ΔfGθ)。讨论了这些热力学参数与溴原子取代数和取代位置的关系,发现这些热力学参数与溴原子取代数和取代位置有很高的相关性。此外,还讨论了结构参数与NPBS的相关性。最高占据分子轨道能量(EHOMO)、分子中最负原子部分电荷(q-)和NPBS之间存在高度相关性,所有R2值均大于0.90。
The structural and thermodynamic properties of 75 polybrominated 5,10-dihydrophenazines (PBDPs) in the ideal gas state at 298.15K and 1.013 × 105 Pa have been calculated at the B3LYP/6-31G* level using the Gaussian 03 program. The isodesmic reactions are developed to calculate the standard enthalpy of formation (ΔfHθ) and standard free energy of formation (ΔfGθ) of PBDP congeners. The relationships of these thermodynamic parameters with the number and position of the Br atom substitution (NPBS) are discussed, and it is found that there exists a high correlation between thermodynamic parameters and NPBS. In addition, the correlations between structural parameters and NPBS are discussed. High correlations were found between the energy of the highest occupied molecular orbital (EHOMO), the most negative atomic partial charge in the molecule (q−) and NPBS, and all R2 values are larger than 0.90.
