Synthesis and investigation of the nonlinear optical properties of various p-aminophenyl sulfone oligomers was written by Mitchell, Michael A.;Tomida, Masayuki;Padias, Anne Buyle;Hall, H. K. Jr.;Lackritz, Hilary S.;Robello, Douglas R.;Willand, Craig S.;Williams, David J.. And the article was included in Chemistry of Materials in 1993.Safety of 1-(4-Hydroxypiperidin-1-yl)ethanone This article mentions the following:
A series of p-aminophenyl sulfone oligomers (monomers, dimers, and trimers) was synthesized with the purpose of studying the effect of several consecutive dipolar units on their second-order nonlinear optical (NLO) characteristics. Three classes of oligomers were synthesized, namely with a hexamethylene, dimethylene, or piperidine spacer. The dipole moments of these oligomers and the μβz value, as measured by EFISH (elec. field induced second harmonic generation), are reported. The results show that these compounds, despite their head-to-tail arrangement, lack the structural features needed to display enhancement of the hyperpolarizability. In the experiment, the researchers used many compounds, for example, 1-(4-Hydroxypiperidin-1-yl)ethanone (cas: 4045-22-1Safety of 1-(4-Hydroxypiperidin-1-yl)ethanone).
1-(4-Hydroxypiperidin-1-yl)ethanone (cas: 4045-22-1) belongs to piperidine derivatives. Piperidine and its derivatives have become increasingly popular in many synthetic schemes. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Safety of 1-(4-Hydroxypiperidin-1-yl)ethanone
