中文摘要:建立了苯-苯、邻苯二甲酰亚胺-苯及邻苯二甲酰亚胺环间作用力模型,利用密度泛函理论中的ωB97XD函数,6-311G(d,p)基组进行了分子优化及环间作用能研究。结果表明,邻苯二甲酰亚胺结构有较好的共平面性。随着环间距离增加,苯-苯、邻苯二甲酰亚胺-苯与邻苯二甲酰亚胺环间体系能量皆先降低后升高,约在3.5?时体系能量最低。静电力对邻苯二甲酰亚胺-苯及邻苯二甲酰亚胺环间作用能影响较大。取代基的引入改变了体系的色散力,降低了体系的能量。优化后邻苯二甲酰亚胺-邻苯二甲酰亚胺、邻苯二甲酰亚胺-苯和苯-苯的作用能分别为-47.78 k J/mol、-34.66 k J/mol和-17.59 k J/mol。

外文摘要:The interaction models of benzene-benzene, phthalimide-benzene and phthalimide-phthalimide rings were established, followed by molecular optimization and the interaction energy research with density functional theory ωB97XD and 6-311G (d,p) basis set. The results showed that phthalimide molecular presented preferable coplanarity. System energy of benzene-benzene, phthalimide-benzene and phthalimide-phthalimide rings decreased firstly and then increased with the increasement of the distance between the rings. The minimum energy appeared at the distance of about 3.5A. Electrostatic force showed a significant impact on the interaction energy of phthalimide-benzene and phthalimide-phthalimide rings. The introduction of substituent groups mainly changed the dispersion force, resulting in the decrease of the system energy. The optimization interaction energy of phthalimide-phthalimide, phthalimide-benzene and benzene- benzene were -47.78 kJ/mol, -34.66 k J/tool and -17.59 kJ/mol, respectively.
