Fluorescent 3-amino-1,8-naphthalimide Tröger’s bases (3-amino-TBNaps) incorporating protected α-amino acids
Abstract The synthesis of 3-amino-1,8-naphthalimide Troger’s base’s (TBNaps) 2–4, possessing several amino acids at the imide terminus, from the corresponding 3-amino-1,8-naphthalimide (Naps) units is described. The solid-state X-ray crystal structure of the related 3-amino-TBNaps piperidino-ethyl derivative 1, and its supramolecular packing is also outlined. In these molecules (as demonstrated from the X-ray structure of 1), the two Naps units have an orthogonal arrangement that makes them potentially attractive β-turn mimics for incorporation into peptide and polypeptide structures. The ground and the excited state properties of these systems were evaluated in a range of solvents that var…
Sulfate-Templated 2D Anion-Layered Supramolecular Self-Assemblies
Summary Using solution and solid-state analyses, we demonstrate that the tripodal N-methylated(1,3,5-benzene-tricarboxamide)-tris(phenylurea) BTA ligands, possessing urea functionalities in the meta position, are able to form extended self-assembly 2D networks via hydrogen bonding templated by sulfate (SO42–). The divergence of the urea binding sites confers a propeller-like conformation to the ligands and is key to formation of the self-assemblies. Studies in solution and in the solid state as well as scanning electron microscopy (SEM) on the self-assembly properties of the ligands showed that the convergence also leads to the formation of hierarchical structures, including porous films an…
