我们研究锯齿状球形胶体，通过耗尽力相互作用。这些体系表现出液-汽相变，其性质由强烈的“锁和钥匙”键和较弱的非特定相互作用的组合决定。随着锁和钥匙绑定倾向的增加，临界点向显著较低的密度移动，共存的相改变了它们的结构。特别是，液体是多孔性的，表现出大的渗漏空隙。这一体系的性质强烈地依赖于基本键网络的拓扑结构：我们评论了这一事实对于具有受控多孔结构的平衡态组装的影响。
We study indented spherical colloids, interacting via depletion forces. These systems exhibit liquid-vapor phase transitions whose properties are determined by a combination of strong “lock-and-key” bonds and weaker nonspecific interactions. As the propensity for lock-and-key binding increases, the critical point moves to significantly lower density, and the coexisting phases change their structure. In particular, the liquid phase is porous, exhibiting large percolating voids. The properties of this system depend strongly on the topological structure of an underlying bond network: we comment on the implications of this fact for the assembly of equilibrium states with controlled porous structures.
