Specifically our group studies the reactions at the surface of organic molecular crystals with vapor dosed adsorbates. From a fundamental standpoint, these reactions are fascinating as geometric considerations (based off molecular orientation in the crystal) appear to be the primary determinant of reactivity and isomer selectivity. Electronic effects appear muted at best. We have been developing composite mechanisms which examine how factors such as the intercalation pathways for adsorbates, the highly anisotropic nature of reaction loci, the relatively weak intermolecular forces within the molecular crystal, and the material’s low surface energies impact reactivity. Fundamental studies are then applied to generate altered surfaces which are then tested for improved interactions with metal top contacts.
