Modulating the Emission Intensity of Poly-(9,9-bis(6‘-N,N,N-trimethylammonium)h...
Monteserín, María; Burrows, Hugh D.; Valente, Artur J. M.; Lobo, Victor M. M.; Mallavia, Ricardo; Tapia, María J.; García-Zubiri, Iñigo X.The interaction between the cationic HTMA-PFP (Poly-(9,9-bis(6‘-N,N,N-trimethylammonium)hexyl-fluorene phenylene) bromide) and oppositely charged sodium n-alkyl sulfonate surfactants of different chain lengths has been studied in DMSO−water solutions (4% v/v) by UV−visible absorption, fluorescence spectroscopy, fluorescence lifetimes, electrical conductivity, and 1H NMR spectroscopy. Polymer−surfactant interact...
