The expression of chirality in adsorption phenomena constitutes an importanttopic, not only relevant to asymmetric transformations involving solidsurfaces, but also to the emergence of homochirality in both terrestrial andextraterrestrial scenarios. Methanol (MeOH) aggregation on graphite/graphene,one of the most idealized adsorbate-adsorbent systems, lead to islands ofcyclic clusters of different sizes (Nano. Lett., 2016, 16, 3142-3147). Here, weshow that this aggregation occurs enantioselectively affording 2D conglomeratesdepending on the size of clusters, in close analogy to a Pasteurian racemate.Homochiral sequences are held together by hydrogen bonding and othernon-covalent interactions, whose absolute configurations can be appropriatelyspecified. A discussion involving the dichotomy between 2D racemates andconglomerates, is offered as well. In addition, the present simulationsshowcase a broad range of acyclic and cyclic structures, even if some discreterings are the dominant species, in agreement with previous experimental dataand theoretical modeling. Our results indicate that MeOH clusters show bindingenergies close to the experimental values, remaining intact at temperatures ashigh as 120 K and up to 150 K.
