Usage

General Description

2,6-diaminonaphthalene, also known as 2,6-naphthalenediamine, is a chemical compound with the molecular formula C10H10N2. It is a highly aromatic compound, composed of a naphthalene ring structure with two amino groups attached at the 2 and 6 positions. This chemical is commonly used as a precursor in the synthesis of various dyes and pigments, due to its ability to undergo diazotization and coupling reactions, resulting in the formation of azo compounds. Additionally, 2,6-diaminonaphthalene has been studied for its potential use in organic electronics and as a component in conductive polymers. It is also known to have mutagenic and carcinogenic properties, and therefore, proper safety precautions must be taken when handling this chemical.

Synthesis of Stable Thiazole-Linked Covalent Organic Frameworks via a Multicomponent Reaction

The development of robust synthetic routes to stable covalent organic frameworks (COFs) is important to broaden the range of applications for these materials. We report here a simple and efficient three-component assembly reaction between readily available aldehydes, amines, and elemental sulfur via a C-H functionalization and oxidative annulation under transition-metal-free conditions. Five thiazole-linked COFs (TZ-COFs) were synthesized using this method. These materials showed high levels of crystallinity, high specific surface areas, and excellent physicochemical stability. The photocatalytic applications of TZ-COFs were investigated, and TZ-COF-4 gave high sacrificial hydrogen evolution rates from water (up to 4296 μmol h-1 g-1 under visible light irradiation) coupled with high stability and recyclability, with sustained hydrogen evolution for 50 h.

Intramolecular interactions in diiodonaphthalenes

The synthesis and the electronic structure of isomeric di-iodonaphthalenes is described. The electronic structure has been investigated by HeI/HeII photoelectron spectroscopy and non-Koopmans' quantum chemical calculations. The influence of the topology of iodine substitution on the electronic structure is discussed. Special emphasis is placed on elucidating the role of intramolecular iodine-iodine interactions.
