New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Grandl, Markus, once mentioned the application of 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, molecular formula is C7H6N2O4. Now introduce a scientific discovery about this category, Quality Control of 4-Amino-3-nitrobenzoic acid.
A series of new pi-conjugated N -> B-ladder boranes has been prepared in high yield by two-fold hydroboration of bifunctional quaterpyridine-, pyrimidine-, and 1,5-naphthyridine-based precursors with 9H-BBN and Piers’ borane ((C6F5)(2)BH). The structures of several ladder-boranes have been confirmed by X-ray crystallography, and their optical and electrochemical properties have been characterized, and complemented by DFT calculations. The electronic structure of the individual ladder boranes, as well as differences in the optical properties that originate from the chemical structure of the boryl-side-chains, are discussed. The results consistently show that, compared to the precursors, the optical gaps of the ladder boranes are significantly reduced, and the electron affinities are strongly increased to between -3.4 and -4.0 eV. Further investigations of chemically and electrochemically reduced species indicate that excess electrons in these kinds of systems are effectively delocalized throughout the conjugated systems.
The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In my other articles, you can also check out more blogs about 1588-83-6. Quality Control of 4-Amino-3-nitrobenzoic acid.
