Order and Mobility of the Fluorescent Probe 1,6-Diphenylhexatriene in a Polyester Liquid Crystal Polymer
نویسندگان
چکیده
We have employed time dependent fluorescence polarization to investigate a main chain semiflexible polyester type liquid crystal polymer using the fluorescent probe 1,6-diphenylhexatriene. We have obtained the second rank order parameter and the tumbling reorientational time of the probeas a functionof temperature. Wehave found the polymer disordering to occur in a temperature range very close to the nematic-isotropic transition.

Aggregation of Cationic Amphiphilic Block and Random Copoly(vinyl ether)s with Antimicrobial Activity
In this study, we investigated the aggregation behaviors of amphiphilic poly(vinyl ether)s with antimicrobial activity. We synthesized a di-block poly(vinyl ether), B3826, composed of cationic primary amine and hydrophobic isobutyl (iBu) side chains, which previously showed antimicrobial activity against Escherichia coli. B3826 showed similar uptake behaviors as those for a hydrophobic fluoresc...
متن کاملMolecular dynamics simulation of a dye molecule in the interior of a bilayer: 1,6-diphenyl-1,3,5-hexatriene in dipalmitoylphosphatidylcholine.
A molecular dynamics simulation was carried out for a dipalmitoylphosphatidylcholine (DPPC) membrane in its liquid crystalline state containing different concentrations of the dye molecule 1,6-diphenyl-1,3,5-hexatriene (DPH). From a numerical analysis of the trajectories, we obtained information concerning structural changes of the membrane due to the presence of the probe and some hydrodynamic...

The effect of the anticancer drug bleomycin on acyl chain order of KB cell membranes was examined by electron paramagnetic resonance and fluorescence polarization spectroscopies using respectively, the 5-doxyl stearic acid spin probe and the 1,6-diphenyl-1,3,5-hexatriene and the 1-[4-(trimethylammonio)phenyl]-6-phenyl-1,3,5-hexatriene fluorescent probes. Measurements of the order parameter, S, ...
متن کاملNanosecond time-dependent fluorescence depolarization of diphenylhexatriene in dimyristoyllecithin vesicles and the determination of "microviscosity".
The nanosecond time dependence of the fluorescence depolarization of 1,6-diphenyl-1,3,5-hexatriene in L-alpha-dimyristoyllecithin vesicles was determined at temperatures above and below the midpoint of the gel-liquid crystalline transition. In neither case could the decay of the total fluorescent emission or the decay of the emission anisotropy be described adequately in terms of single exponen...
متن کاملAdsorption of a cholesteric liquid crystal polyester on silver nanoparticles studied by surface-enhanced Raman scattering and micro Raman spectroscopy.
A Raman study of the adsorption of thermotropic cholesteric liquid crystal polyester PTOBDME ([C(34)H(36)O(8)](n)) on Ag surfaces is presented in this work. The affinity and adsorption mechanism of this polymer was tested on Ag metal colloids and on Ag films obtained by direct immobilization of the colloidal nanoparticles. We have first studied the structure of PTOBDME suspended in several solv...
