Electrochemistry of LB films of mixed MGDG:UQ on ITO.
The electrochemical behaviour of biomimetic monolayers of monogalactosyldiacylglycerol (MGDG) incorporating ubiquinone-10 (UQ) has been investigated. MGDG is the principal component in the thylakoid membrane and UQ seems a good substitute for plastoquinone-9, involved in photosynthesis chain. The monolayers have been performed using the Langmuir and Langmuir-Blodgett (LB) techniques and the red...
متن کاملRole of various LB parameters on the optical characteristics of mixed Langmuir–Blodgett films
This communication reports the spectroscopic characterizations of mixed Langmuir–Blodgett (LB) films of non-amphiphilic N,N-bis (2,5-di-tert-butylphenyl)3,4,9-perylenedicarboximide (DBPI) molecules, mixed with polymethyl methacrylate (PMMA) and stearic acid (SA). Jaggregates of DBPI molecules in the mixed LB films have been confirmed by UV–Vis absorption spectroscopic study. Formation of organi...
متن کاملHighly ordered LB films of DHAP: a donor acceptor substituted polyene
The donor acceptor substituted polyene 5-(4-dihexadecylaminophenyl)-2-methyl-2,4-pentadienal (DHAP) is--due to its amphiphilic nature--a promising candidate for the Langmuir-Blodgett (LB) technique. The molecule was studied as a monolayer on a pure water surface under argon atmosphere. Monolayers and multilayers were transferred onto solid support. The films showed a high degree of order in the...
متن کاملLuminescent Properties of Europium Complexes with Different Long Chains in Langmuir-Blodgett (LB) Films
A series of europium(III) complexes with different chain length, tris [2-m-pyridylmethanamido-5-phenyl(1,3,4)-oxadiazole] mono [2-(4-n-alkylphenyl)-iminazole (4,5-f)-1,10-phenanthroline] Eu(III) [Eu(PMA)3Nn (n = 6, 10, 14,18)] were synthesized. All of these amphiphilic europium(III) complexes could form stable Langmuir film at air/water interface and could be transferred onto hydrophilic quartz...
متن کاملMolecular Arrangement and Recognition of a New Bolaform Cinnamic Acid Derivative in LB Films*
A bolaamphiphile containing cinnamic acid moiety, [4鄄(10鄄hydroxydecanyloxy)鄄10鄄hydroxydecanyl鄄 cinnamate, abbreviated HDC], was synthesized and the LB films of HDC were studied. It was found from the results of 仔-A isotherms that multilayers of HDC were formed at the air/water interface. The photoreaction of HDC in LB films induced by UV light was investigated with UV and IR measurements. Photo...
