Article Abstract

The conformation of the title compound, CHFO, is cone-shaped, partially determined by intra-molecular C-H⋯O short contacts. The benzene rings at the top of the cone are inclined to one another by 73.10 (7)°, while the benzene rings at the bottom of the cone are inclined to one another by 35.49 (8)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯F hydrogen bonds, forming a three-dimensional supra-molecular structure. There are also C-H⋯π contacts present within the framework structure.

Arene-Cucurbiturils: Benzene-Containing Cucurbituril[2,4] and Benzene-Containing Cucurbituril[3,6].

Org Lett

Department of Chemistry, College of Chemistry and Chemical Engineering, Guizhou University, Guiyang 550025, P. R. China.

Benzene-containing cucurbituril[2,4] and benzene-containing cucurbituril[3,6], the structures of cucurbit[]urils with some glycoluril units replaced by benzene rings, are constructed through condensation of specific benzene-containing motifs. These novel macrocycles inherit cucurbit[]urils' concave cavity and provide chemical modification potentiality and chromophores. Benzene-containing cucurbituril[2,4] shows a -symmetric macrocycle, while benzene-containing cucurbituril[3,6] exhibits a distinctive two-cavity structure (one big and one small) that resembles a gourd and could potentially accommodate two guests different in size simultaneously.

Stacking interactions are a recurring motif in supramolecular chemistry and biochemistry, where a persistent theme is a preference for parallel-displaced aromatic rings rather than face-to-face π-stacking. This is typically explained in terms of quadrupole-quadrupole interactions between the arene moieties but that interpretation is inconsistent with accurate calculations, which reveal that the quadrupolar picture is qualitatively wrong. At typical π-stacking distances, quadrupolar electrostatics may differ in sign from an exact calculation based on charge densities of the interacting arenes.

Constructing conical helices inside carbon nanocones.

Phys Chem Chem Phys

January 2025

School of Mechanical & Vehicle Engineering, Linyi University, Linyi, Shandong 276000, China.

Molecular dynamics simulations demonstrate that regular conical helices of poly(-phenylene) (PPP) chains can be constructed inside the confined space of single-walled carbon nanocones (CNCs). The translocation displacement of the PPP chain combined with the change of the system total potential energy including each energy component and structural parameters of the formed conical helix is discussed to deeply explore the microstructure evolution, driving forces and dynamic mechanisms. In addition, the influence of chain length, cone angle, temperature, chain number, linked position of benzene rings and the form of Lennard-Jones potential on the helical encapsulation is further studied.

Coumarins, a group of naturally occurring compounds, have been reported to demonstrate anticancer potential. These substances, distinguished by their combined benzene and α-pyrone rings, have been demonstrated to impact multiple cellular mechanisms essential for the initiation and advancement of cancer. These agents work in different ways that prevent different tumor cells from growing, spreading, and increasing.

Background: Polycyclic aromatic hydrocarbons (PAHs) are one of the most dangerous persistent organic pollutants in the environment. Due to the discharge of chemical plants and domestic water, the existence of PAHs in sea water and lake water is harmful to human health. A method for rapid detection and removal of PAHs in water needs to be developed.
