Luminescent 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 کاملSegmental orientation of a single polymer chain in LangmuirBlodgett films studied by defocus fluorescence imaging
INTODUCTION Amphiphilic polymers, such as poly(alkyl methacrylate)s and poly(alkyl acrylamide)s, are known to form stable monolayers on a water surface by the Langmuir–Blodgett (LB) method.1,2 The polymer monolayer has an ultimate thinness of the size of the monomer unit, and it has few defects in the film plane. Therefore, the monolayer of an amphiphilic polymer has attracted much interest as ...
متن کاملTwo-component Langmuir monolayers and LB films of DPPC with partially fluorinated alcohol (F8H9OH).
The interaction of (perfluorooctyl)nonanol (F8H9OH) with dipalmitoylphosphatidylcholine (DPPC) was systematically studied in two-component monolayers at air-water interface. The thermodynamic property and phase morphology of the monolayers were investigated by isotherm measurements and several microscopic methods such as Brewster angle microscopy, fluorescence microscopy, and atomic force micro...
متن کاملInterfacial properties in Langmuir monolayers and LB films of DPPC with partially fluorinated alcohol (F8H7OH).
Two-component interactions between (perfluorooctyl) heptanol (F8H7OH) and dipalmitoylphosphatidylcholine (DPPC), which is a major component of pulmonary surfactants in mammals, were systematically elucidated using Langmuir monolayers and Langmuir-Blodgett (LB) films of the compounds. The interactions such as the miscibility of the compounds and their phase behavior were examined from thermodyna...
