Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity

Angewandte Chemie, EarlyView.
This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

Angewandte Chemie, EarlyView.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Euchrestifolines A–O, fifteen novel carbazole alkaloids with potent anti-ferroptotic activity from Murraya euchrestifolia

Natural Products and Bioprospecting
Fifteen novel carbazole alkaloids, euchrestifolines A–O (1–15), were obtained from Murraya euchrestifolia. Their structures were elucidated by spectroscopic analysis, Mosher’s ester, calculated ECD, and transition metal complex ECD methods.

Molecular docking studies on binding specificity of 3,6- and 2,7-carbazoles with DNA duplexes

European Journal of Biological Research, 2020
Molecular docking is a widely used computational technique used to find the probabilistic binding sites of drugs in the vicinity of macromolecules. The drugs produce their working effect only when they bind and interact with the target macromolecule. The

Oxidation of Carbazole.

Journal of Synthetic Organic Chemistry, Japan, 1965
In the oxidation of carbazole, two isomers of dicarbazyl are formed as main reaction products. 3, 3'-Dicarbazyl is formed by bichromate or permanganate oxidation in acetic acid, whereas 9, 9'-dicarbazyl is formed by permanganate oxida tion in acetone.
