When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. In an article, author is Li Zhan-Xian, once mentioned the application of 126-30-7, Name is 2,2-Dimethylpropane-1,3-diol, molecular formula is C5H12O2. Now introduce a scientific discovery about this category, SDS of cas: 126-30-7.
The synthesis, characterization, spectroscopic properties of a new ligand 1,2-bis[2-(4-methyl-7-acetyl-amino-1,8-naphthyridine)]ethylene (L) and its two binuclear Cu(I) complexes containing triphenylphosphine (PPh3) or bis(diphenylphosphino)methane (dppm), [Cu-2(L)(PPh3)(4)](BF4)(2)center dot 2CH(2)Cl(2) (1 center dot 2CH(2)Cl(2)) and [Cu-2(L)(dppm)(2)](BF4)(2)center dot 4H(2)O (2 center dot 4H(2)O) are reported. The structural investigation of these compounds based on X-ray crystal analysis shows that the copper(I) centers adopt different coordination geometries, O(N)CuP2+ and NCuP2+ for complexes 1 and 2, respectively. Upon irradiation of a degassed organic solution of L at 365 nm, photoinduced isomerization reaction and an intramolecular proton transfer of ligand L were detailed studied by absorption spectral changes. A spectroscopic investigation involving time-dependent density functional theory calculations allows assignment of the excited states that relate to emission and transient absorption spectra. The observed lower-energy absorption bands appearing in the region of 413 and 418 nm for 1 and 2 in dichloromethane are assigned to ligand-to-ligand charge transfer (LLCT, phosphine -> napy) transition in nature. Compared with well-structured solid-state emission originating from pi pi* transition of ligand L, complexes 1 and 2 exhibit intense room-temperature solid-state emissions with lambda(max) at 586 and 620 nm, respectively. The energy and the shape of the emission bands are clearly different from that of the ligand, indicating the emissions come from different excited states. (C) 2011 Elsevier B.V. All rights reserved.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 126-30-7 is helpful to your research. SDS of cas: 126-30-7.
