摘要：

Adding astutely placed methyl groups to hexaphenylbenzene increases molecular weight but simultaneously weakens key C-H center dot center dot center dot pi interactions, thereby leading to decreased enthalpies of sublimation and showing that materials with abnormally weak cohesion can be made by identifying and then obstructing interactions that help control association.
