Name: 4-IodopyridineIn 2019 ,《Influence of Donor-Substituents on Triphenylamine Chromophores Bearing Pyridine Fragments》 appeared in European Journal of Organic Chemistry. The author of the article were Tydlitat, Jiri; Feckova, Michaela; le Poul, Pascal; Pytela, Oldrich; Klikar, Milan; Rodriguez-Lopez, Julian; Robin-le Guen, Francoise; Achelle, Sylvain. The article conveys some information:
Efficient synthetic routes that combine different palladium-catalyzed cross-coupling reactions were developed for the preparation of a new family of push-pull derivatives in which pyridine was used as the acceptor group and different para-substituted diphenylamines as the donor groups. All compounds showed absorption in the UV/visible region and blue-green emission with high quantum yields. Significant red shifts were observed in the absorption and fluorescence emission maxima on increasing the electron-donating ability of the substituents or on incorporating a π-conjugated linker. This finding can be explained on the basis of enhanced intramol. charge transfer (ICT). Strong emission solvatochromism confirmed the formation of an intramol. charge-separated emitting state. The HOMO-LUMO energy gaps were estimated by exptl. electrochem. measurements and the results were interpreted with the aid of DFT calculations The thermal behavior of all materials also was studied by DSC. In the experimental materials used by the author, we found 4-Iodopyridine(cas: 15854-87-2Name: 4-Iodopyridine)
4-Iodopyridine(cas: 15854-87-2) is a halogenated heterocycle that is a building block for proteomics research. 4-Iodopyridine is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists.Name: 4-Iodopyridine
