Interplay of electrostatic and hydrophobic effects with binding of cationic gemini surfactants and a conjugated polyanion: Experimental and molecular modeling studies
Article Abstract:
The interaction between the anionic poly{1,4-phenylene-[9,9-bis(4-phenoxy-butylsulfonate)]fluorene-2,7-diyl}copolymer (PBS-PFP) and cationic gemini surfactants are studied in aqueous solution. The surface tension experiments show that presence of the polymer does not affect the surfactant critical micelle concentration (CMC), while small-angle neutron scattering (SANS) studies have shown the formation of spherical aggregates and has suggested a slight increase in radius, compatible with PBS-PFP/micelle interactions.

Structure and phase equilibria of polyelectrolytic hairy-rod supramolecules in the melt state
Article Abstract:
The structure formation and phase behavior of supramolecular hairy-rod polymers consisting of rodlike polymer chains with physically bonded side chains are investigated in the melt state using small-angle X-ray scattering. In accordance with the theory, there is a strong tendency to microphase separation. There are three kinds of microphase-separated phases observed, two of which contain rodlike assemblies in square (Sq) and oblique (Obl) lattices, and the third phase is lamellar (Lam).

Solubilization of polyelectrolytic hairy-rod polyfluorene in aqueous solutions of nonionic surfactant
Article Abstract:
A report is presented on the solubilization, phase behavior, and self-organized colloidal structure of a ternary water-polyfluorene-surfactant system comprised of polyelectronic {1,4-phenylene[9,9-bis(4-phenoxybutylsulfonate)]fluorene-2,7-diyl} in nonionic pentaethylene glycol monododecyl ether [[C.sub.12][E.sub.5]]. The way in which a high amount of polyfluorene can be solubilized by aqueous [C.sub.12][E.sub.5] through aggregate formation is shown.
