Self-sorting the ability of molecules and entities to efficiently distinguish between self and non-self is common in biology but relatively rare in non-natural systems. We report that compounds 1 and 2 form tightly self-associated dimers in chloroform that display high levels of chiral discrimination and self-sorting. These tightly self-associated H-bonding modules are driven by simultaneous formation of pi-pi and H-bonding interactions. The confluences of these properties render the dimers prime modules for use in advanced applications. We will present our latest efforts toward understanding the factors governing self-sorting in these systems (e.g. H-bond number and geometry, chirality and solvent dependence).
