Two-dimensional (2D) nanorod meshes made of benzoperylene-1,3-dicyanotetrafluorobenzene (BP-1,3-DTFB) were formed via crystal transformation of the pre-existing BP microsheets. The transformation was driven by a cooperative effect of intermolecular charge-transfer and arene-perfluoroarene interactions. Epitaxial growth of cyan-emitting BP-1,3-DTFB nanorod meshes was directed by small lattice mismatch between BP and BP-1,3-DTFB, followed by the consumption of BP and the formation of BP-1,3-DTFB. Such a crystal transformation strategy can also be used to guide the formation of BP-1,4-dicyanotetrafluorobenzene (BP-1,4-DTFB) nanorod meshes. The present work reports a simple yet effective approach for the realization of aligned organic nanorod superstructures.
