Micellar counterion binding for alkylpyridinium iodides probed by N-sulfopropylacridinium fluorescence quenching was written by Asakawa, Tsuyoshi;Iriyama, Keisuke;Ohta, Akio;Miyagishi, Shigeyoshi. And the article was included in Journal of Oleo Science in 2004.Application In Synthesis of 1-Dodecylpyridin-1-ium bromide This article mentions the following:

Fluorescence quenching using N-sulfopropylacridinium (SPA) makes it possible to determine the degree of micellar counterion binding (灏? of alkylpyridinium iodide in aqueous solution But with quinoline derivatives as a halide-sensitive fluorescence probe, this was not possible. Fluorescence was quenched by iodide ions as indicated by linear Stern-Volmer plots, the slope of which was noted to decrease beyond cmc (critical micelle concentration) owing to micellar counterion binding with SPA excitation at 416 nm. The slope was found to significantly increase beyond cmc with SPA excitation at 357 nm. The abrupt quenching was due to absorption bands resulting from charge-transfer interactions of pyridinium and iodide ions. SPA fluorescence was quenched by iodide and bromide ions but virtually unaffected by nitrate or sulfate ions. Selective counterion binding of iodide ions is thus shown to be detectable. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Application In Synthesis of 1-Dodecylpyridin-1-ium bromide).

Syndiotactic- and heterotactic-specific radical polymerizations of N-n-propyl-浼?fluoroacrylamide and phase-transition behaviors of aqueous solutions of poly(N-n-propyl-浼?fluoroacrylamide) was written by Hirano, Tomohiro;Furutani, Takahiro;Oshimura, Miyuki;Ute, Koichi. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2012.Quality Control of 3,5-Dimethylpyridine 1-oxide This article mentions the following:

Radical polymerization of N-n-propyl-浼?fluoroacrylamide (NNPFAAm) was studied in several solvents at low temperatures in the presence or absence of Lewis bases, Lewis acids, alkyl alcs., silyl alcs., or fluorinated alcs. Different effects of solvents and additives on stereospecificity were observed in the radical polymerizations of NNPFAAm and its hydrocarbon analogs such as N-isopropylacrylamide (NIPAAm) and N-n-propylacrylamide (NNPAAm); for instance, syndiotactic (and heterotactic) specificities were induced in radical polymerization of NNPFAAm in polar solvents (and in toluene in the presence of alkyl and silyl alcs.), whereas isotactic (and syndiotactic) specificities were induced in radical polymerizations of the hydrocarbon analogs under the corresponding conditions. In contrast, heterotactic specificity induced by fluorinated alcs. was further enhanced in radical polymerization of NNPFAAm. The effects of stereoregularity on the phase-transition behaviors of aqueous solutions of poly(NNPFAAm) were also studied. Different tendencies in stereoregularity were observed in aqueous solutions of poly(NNPFAAm)s from those in solutions of the hydrocarbon analogs such as poly(NIPAAm) and poly (NNPAAm). The polymerization behavior of NNPFAAm and the phase-transition behavior of aqueous poly(NNPFAAm) are discussed based on possible fluorine-fluorine repulsion between the monomer and propagating chain-end, and neighboring monomeric units. 婕?2012 Wiley Periodicals, Inc.
