Reference of 1271-48-3, hemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. In a document type is Article, molecular formula is C12H10FeO2, molecular weight is 242.0516, and a compound is mentioned, 1271-48-3, 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery.
With an objective to understand the nonlinear optical properties of organometallic structures, various aryl and vinyl derivatives of ferrocene were synthesized and their nonlinear optical properties were investigated by using degenerate four-wave mixing.The molecular second hyperpolarizability gamma increases strongly with the length of the conjugated ?-electron system.The results show that effective conjugation is determined predominantly by the length of the aryl-vinyl system; the contribution from the ferrocenyl group is less significant.The d-d resonance of the metal in the ferrocene unit does not appear to make an important contribution to optical nonlinearity.The experimental results on ferrocene are compared with those from a recent theoretical study using semiempirical calculations.Although a qualitative agreement with the theoretical result is found, the experimental value of gamma determined by our method is about 4 times larger.Possible sources of such discrepancies are discussed.
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool.Reference of 1271-48-3. In my other articles, you can also check out more blogs about 1271-48-3
