Abstract

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 non-specific 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.
