The attractive interaction between carbonyl oxygens and the π-face of aromatic surfaces was studied using N-phenylimide molecular rotors. The C═O···Ar interactions could stabilize the transition states but were half the strength of comparable C═O···C═O interactions. The C═O···Ar interaction had a significant electrostatic component but only a small orbital delocalization component.
使用N-苯基酰亚胺分子转子研究了羰基氧与芳族表面的π-面之间的有吸引力的相互作用。C=O···Ar 相互作用可以稳定过渡态,但强度是可比较的 C=O···C=O 相互作用强度的一半。C=O···Ar相互作用具有显着的静电分量,但只有很小的轨道离域分量。
