Second - Harmonic Generation in Purple Membrane - Poly ( vinyl alcohol ) Films : Probing
The second-order nonlinear optical properties of purple membrane-poly(viny1 alcohol) films (PM-PVA) are investigated by second-harmonic generation. The magnitudes and the phases of the second-order molecular polarizabilities of the bacteriorhodopsin molecule in the bR570 and MdI2 states are obtained. Comparing these results with those obtained for free retinal and retinal Schiff bases spread at...
متن کاملSynthesis and Evaluation of Fatty Hydrazides Based on Schiff Bases from Oil Processing Industries Byproducts
Schiff bases of fatty acid hydrazides made from Oil recovered from spent bleaching earth (ORSBE) and Acid oil (AO)were prepared. These newly synthesized Schiff bases were characterized on the basis of FT-IR, elemental analysis and evaluated for biological performance. Schiff bases exhibited mild antibacterial activities against certain micro-organisms if compared with streptomycin used as stand...
متن کاملHemicyanine Langmuir-Blodgett Films by Fourier Transform Infrared Spectroscopy and Second Harmonic Generation
The molecular orientation in amphiphilic hemicyanine Langmuir-Blodgett (LB) films has been studied quantitatively by Fourier transform infrared (FTIR) spectroscopy and second harmonic generation (SHG). From the analysis of transmission and reflection absorption (RA) spectra of FTIR, the tilt angles to the surface normal of the hydrocarbon chain axis and the chromophore of amphiphilic hemicyanin...
متن کاملSecond Harmonic Generation Diagnostic of Layer by Layer Deposition from Disperse Red 1–Functionalized Maleic Anhydride Copolymer
Layer-by-layer (LBL) electrostatic assembly of poly-electrolytes is proving to be an increasingly rich and versatile technique for the formation of multilayered thin films with a wide range of electrical, magnetic, and optical properties. In the present work we synthesized a new nonlinear optical (NLO) maleic acid copolymer containing Disperse Red 1 moieties, built-up multilayer assemblies by a...
متن کاملOne Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases
Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.
