3/3/2023 0 Comments Triangular tessellation![]() In the CT-B superstructure, the CHCl 3 lattice molecules establish a set of and intermolecular interactions, leading to the formation of a hexagonal grid of solvent in which NDI-Δ forms a triangular grid. Confinement of TTF inside the NDI-Δ cavities in the CT-A superstructure enhances the CT character with the observation of a broad absorption band in the NIR region. Solvent modulation plays a critical role in controlling not only the NDI-Δ: TTF stoichiometric ratios and the molecular arrangements in the crystal superstructures, but also prevents the inclusion of TTF guests inside the cavities of NDI-Δ. Using MeCN, CHCl 3, and CH 2Cl 2, we identified three sets of cocrystals, namely CT-A, CT-B, and CT-C, respectively. Different solvents lead to different packing arrangements. Cocrystallization of NDI-Δ with tetrathiafulvalene ( TTF) leads systematically to the formation of 2D tessellations as a result of superstructure-directing CT interactions. Utilization of nonhalogenated solvents, combined with careful tailoring of the concentrations, results in NDI-Δ self-assembling though interactions into 2D honeycomb triangular and hexagonal tiling patterns. Our approach to exploring the 3D topology of 2D tessellations of a naphthalene diimide-based molecular triangle ( NDI-Δ) reveals that the 2D molecular arrangement is sensitive to the identity of the solvent and solute concentrations. Some types of computer analysis of a constructed design require an adaptive mesh refinement, which is a mesh made finer (using stronger parameters) in regions where the analysis needs more detail.Tessellation of organic polygons though and charge-transfer (CT) interactions offers a unique opportunity to construct supramolecular organic electronic materials with 2D topologies. This parameter ensures that even very small humps or hollows that can have significant effect to analysis will not disappear in mesh.Īn algorithm generating a mesh is typically controlled by the above three and other parameters. The maximum allowed angle between two adjacent approximation polygons (on the same face). ![]() This parameter ensures enough detail for further analysis.
