Stacks on stacks on stacks

Finding ways to create order is a common theme in science. Here researchers are trying to carefully arrange chromophores in order to create better solar cells (among other potential uses). In particular, these chemists are trying to make porphyrins stand up on a surface creating stacks of porphyrins that are a well defined distance from each other and from the surface they are attached to.
