Novel redox-active ionic thermotropic liquid crystalline complexes of polyelectrolyte and ferrocenyl surfactants

Redox-active polyelectrolyte-surfactant complexes（PSC） were prepared via the ionic self-assembly of sodium poly（styrenesulfonate） （PSS） and ferrocenyl surfactant,（11-ferrocenylundecyl）trimethylammonium bromide（FTMA） in aqueous solution. The PSS-FTMA complex exhibited an ordered interdigitated monola...

Description
Summary:Redox-active polyelectrolyte-surfactant complexes（PSC） were prepared via the ionic self-assembly of sodium poly（styrenesulfonate） （PSS） and ferrocenyl surfactant,（11-ferrocenylundecyl）trimethylammonium bromide（FTMA） in aqueous solution. The PSS-FTMA complex exhibited an ordered interdigitated monolayer mesomorphous structure with the long period of d = 3.13 nm,and was in the ionic thermotropic liquid crystal SmA state at room temperature.Interestingly,in the solid complex, the ferrocenyl moieties formed H-aggregation showing an increase in theπ-π~＊ energy transfer of cyclopentadienes in the ferrocene moieties as known from the blue-shift in the UV spectrum.The complexes showed higher thermal stability compared with their components due to the ionic interaction.The PSS-FTMA film had a good redox reversibility,which promised to be used in electrochemical sensors.
