lamellar crystal. Thus, the surfaces of these crystals were covered by side-branches. By using carboxyl groups as side-branches, which allow for chemical reactions, we could functionalize the crystal with semiconductingmolecules. Here, we compare properties of crystals differing in size: small
polymer from solution. Attachment of the semiconductingmolecules to the lamellar surface of large single crystals was possible, however, only after an appropriate annealing procedure. As a function of the duration of the grafting process, the morphology of the resulting layer of semiconductingmolecules
changed from patchy to compact.

Organic chemistry constantly provides new, high-performance semiconductingmolecules for organic electronic applications [1]. However, efforts to develop
