Synthetic Route of 5423-54-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 5423-54-1, 1,5-Naphthyridin-4-ol, introducing its new discovery.
4-Hydoxy-1,5-naphthyridines (HNt) are derivatives of 8-hydroxyquinolines, yet possess a wider HOMO and LUMO band gap than the latter. The cyclometalated complex of platinum(II) with Nt exists in a square planner geometry, and has a high tendency to aggregate in condensedmedia. Such a phenomenon was verified by examining its photo-luminescence spectra in different concentrations. In a dilute solution, it exhibits a yellow phosphorescence centered at 530?555 nm, yet red-shifted to ?660 nm in a concentrated solution or in the solid state. This series of compounds can be used as emitting dyes in light-emitting diodes (LED). The LED devices with a configuration ITO/NPB/dye (6%) in CBP/BCP/AlQ3 or TPBI/LiF/Al displayed a yellow to red color, where NPB, CBP, BCP, AlQ3 and TPBI denote 4,4?-bis[N-(1-naphthyl), Nphenylamino] biphenyl, 4,4?-bis(carbazol-9-yl)biphenyl, 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, tris(8-hydoxyquinolinato) aluminium, and 2,2?,2?-(1,3,5-benzenetriyl)tris(1-phenyl-1H- benzimidazole), respectively. The maximal light intensity exceeds 2.6 ¡Á 104 cd/m2 with an external quantum efficiency up to 5.8%.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 5423-54-1. In my other articles, you can also check out more blogs about 5423-54-1
