Usage

General Description

2,7-Dibromopyrene is a chemical compound that is part of the pyrene family, which is a polycyclic aromatic hydrocarbon (PAH). It is a yellow solid at room temperature and is insoluble in water. 2,7-Dibromopyrene is primarily used in the manufacturing of pharmaceuticals, dyes, and other organic chemicals. It is also used in research as a reagent and intermediate for the synthesis of other chemical compounds. However, it is important to note that 2,7-Dibromopyrene is a hazardous substance and should be handled with care, as it is toxic and may cause skin and eye irritation upon contact. Its disposal and usage should be in accordance with proper safety and environmental guidelines.

Dysprosium-carboxylate nanomeshes with tunable cavity size and assembly motif through ionic interactions

We report the design of dysprosium directed metallo-supramolecular architectures on a pristine Cu(111) surface. By an appropriate selection of the ditopic molecular linkers equipped with terminal carboxylic groups (TPA, PDA and TDA species), we create reticular and mononuclear metal-organic nanomeshes of tunable internodal distance, which are stabilized by eight-fold Dy?O interactions. A thermal annealing treatment for the reticular Dy:TDA architecture gives rise to an unprecedented quasi-hexagonal nanostructure based on dinuclear Dy clusters, exhibiting a unique six-fold Dy?O bonding motif. All metallo-supramolecular architectures are stable at room temperature. Our results open new avenues for the engineering of supramolecular architectures on surfaces incorporating f-block elements forming thermally robust nanoarchitectures through ionic bonds.

Molecular compasses and gyroscopes. II. Synthesis and characterization of molecular rotors with axially substituted bis[2-(9-triptycyl)ethynyl]arenes

We have developed a simple convergent procedure for the synthesis of molecular rotors consisting of a central aromatic group coupled with two axially positioned ethynyltriptycenes. Molecular rotors with 1,4-phenylene (1), 1,4′-1,1′-biphenylene (2), 9, 10-anthracenylene (3), and 2,7-pyrenylene (4) groups were prepared by Pd(0)-catalyzed coupling of ethynyl triptycenes with the corresponding dibromoarenes. Although compounds 1-4 were not expected to have free rotation in the solid state, the rotational potentials of 1 and 3 were analyzed by semiempirical methods and the crystal packing of 1 was analyzed to design the structures most likely to yield a functional rotor in the solid state. Semiempirical PM3 calculations predict compounds 1, 2, and 4 to have frictionless internal rotation even at temperatures as low as 25 K, while compound 3 is expected to have a barrier of ca. 4 kcal/mol.
