Bildungsweise, Struktur und Anwendungsmöglichkeiten von Komplexen zwischen Polyelektrolyten und ionischen Farbstoffen (Literaturübersicht). Teil I: Einführung und Überblick über Komplexe zwischen kationischen Polyelektrolyten und anionischen Farbstoffen

Abstract

Anhand der einschllgigen Literatur wird ein ifberblick uber Bildungsweise und Struktur von Komplexen zwischen kationischen Polyelektrolyten und anionischen Farbstoffen gegeben. Nach einigen Bemerkungen zur experimentellen Methodik wird unter Betonung unterschiedlicher Moglichkeiten der Farbstoff-Polymer-Bindung eine nach Polymerklassen gegliederte stomiche Systematik gegeben, wobei der Schwerpunkt bei den synthetischen Polymeren mit kationischen Gruppen und von Seiten der Farbstoffkomponente bei Methylorange und seinen Homologen liegt. Formation, structure and application of complexes of polyelectrolytes and ionic dyes (review) Part I. Introduction and survey on complexes between cationic polyelectrolytes and anionic dyesMode of formation and structure ofcomplexes between cationic polyelectrolytes and anionic dyes are reviewed on the basis of the relevant literature, accentuating the various ways of binding the dye onto the polymer. After some remarks on the experimental techniques employed, a systematic survey is presented according to classes of polymers, centering on synthetic polymers with cationic sites and regarding the anionic dyes on methyl orange and its homologues.

Nonmonotonic Effect of Ionic Strength on Surface Dye Extraction during Dye−Polyelectrolyte Multilayer Formation

“…Polyelectrolyte−dye complexation in solution has been extensively studied. − It is believed that these interactions depend strongly on electrostatic forces between the polymer and the dye, on the polymer's persistence length or conformational adaptability, and on the polymer's degree of cross linking. , In general, a linear polymer complexes dye less efficiently than a coiled or cross-linked polymer . These factors probably influence dye extraction from a surface by the polyion during multilayer formation.…”

Polyelectrolytes as new matrices for secondary ion mass spectrometry

“…After mixing, their mixtures were cloudy, suggesting complexation between the analyte and the PE. Complexation has previously been observed in solution between PEs and water-soluble, charged organic dyes [18,19]. Some enhancement in ion yield was also observed from a dried droplet of a simple binary solution of an analyte and a polyelectrolyte.…”

Interaction of dis‐azo dyes with quaternized poly(dimethylaminoethyl methacrylate) as a function of the dye structure and polycation charge density

“…Many scientists in the field have pointed out that the main driving force in the interaction between polyelectrolytes and ionic dyes is the Coulomb interaction, that is, the charge neutralization of the dye charges by oppositely charged polyions 15–18. In our previous investigations, PCs containing quaternary ammonium groups in the backbone were synthesized19, 20 and used in the separation of montmorillonite21 and in dye removal 22.…”
