Excited-State Structure and Delocalization in Ruthenium(II)-Bipyridine Complexes That Contain Phenyleneethynylene Substituents was written by Wang, Yingsheng;Liu, Shengxia;Pinto, Mauricio R.;Dattelbaum, Dana M.;Schoonover, Jon R.;Schanze, Kirk S.. And the article was included in Journal of Physical Chemistry A in 2001.Category: iodides-buliding-blocks This article mentions the following:
A comprehensive photophys. study was carried out on the two prepared complexes [(bpy)2Ru(4,4′-PE-bpy)]2+ and [(bpy)2Ru(5,5′-PE-bpy)]2+ (44Ru and 55Ru, resp., where bpy = 2,2′-bipyridine and PE = phenyleneethynylene 4-Et2NCOC6H4CC-). The objective of this work is to determine the effect of the phenyleneethynylene substituents on the properties of the metal-to-ligand charge-transfer excited state. The complexes were characterized by using UV-visible absorption, photoluminescence, and UV-visible and IR transient absorption spectroscopy. The results indicate that the MLCT excited state is localized on the PE-substituted bpy ligands. Also, the photophys. data indicate that in the MLCT excited state the excited electron is delocalized into the PE substituents and the manifestations of the electronic delocalization are larger when the substituents are in the 4,4′-positions. In the experiment, the researchers used many compounds, for example, N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8Category: iodides-buliding-blocks).
N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Category: iodides-buliding-blocks
