Vinyl sulfones

Acta Crystallographica Section C Crystal Structure Communications, 2008
Four neutral vinyl sulfones, two of which are paired with phosphonate groups, are described. The compounds are diisopropyl (2-phenylethenylsulfonylmethyl)phosphonate, C(15)H(23)O(5)PS, (I), diisopropyl {[2-(7-methoxy-1,3-benzodioxol-5-yl)ethenylsulfonyl]methylsulfonylmethyl}phosphonate, C(18)H(27)O(10)PS(2), (II), bis(trans-2-phenylethenyl) sulfone, C ...

Sulfone-linked paracyclophanes

Chemical Communications, 1998
Oxidation of the macrocyclic thioether sulfones (SϕSO2ϕ)n (ϕ = 1,4-phenylene; n = 2 or 3) affords sulfone-linked paracyclophanes (ϕSO2)4 and (ϕSO2)6; single crystal X-ray analysis reveals the tetramer, (ϕSO2)4, to be a near-perfect square box, whilst the hexamer, (ϕSO2)6, adopts a much more irregular conformation; exhaustive oxidation of (SϕSO2ϕ)4 ...

Amphiphilic perfluoroalkylated sulfones and sulfonate betaines

Journal of Fluorine Chemistry, 2007
Abstract Two types of perfluoro alkyl-containing amphiphilic sulfones 7 – 9 and 13 – 15 , respectively, and sulfonate betaines 23 – 32 were prepared using 2-[(perfluoroalkyl)methyl]oxiranes ( 1–3 , R F  = C 4 F 9 , C 6 F 13 , C 8 F 17 ) or 3-(perfluoroalkyl)propyl iodides ( 16 and 17 , R F  = C 6 F 13 , C 8 F 17 ) as the starting compounds ...

Synthesis of nucleoside sulfonates and sulfones

Tetrahedron Letters, 1991
Abstract Sulfonate analogues of adenine, cytidine and guanine monophosphates have been synthesized for the first time. The synthesis of ribose 3-sulfonate, a synthesis of sulfonyl disaccharides and dinucleotides and an improved synthesis of a ribose 3-sulfone is also reported.

Polybenzimidazole block sulfonated poly(arylene ether sulfone) ionomers

Chemical Communications, 2011
Novel ionomers based on polybenzimidazole block sulfonated poly(arylene ether sulfone) show excellent thermal properties. The ionic aggregation of sulfonic acid groups leads to well-developed phase separated morphology and thus high proton conductivity at wide humidity range, up to 65 mS cm(-1) at 90% relative humidity.

Sulfonated poly(ether sulfone ether ketone ketone)/sulfonated poly(ether sulfone) blend membranes with reduced methanol permeability

High Performance Polymers, 2012
Proton exchange membranes were prepared by blending sulfonated poly(ether sulfone ether ketone ketone) (SPESEKK) with sulfonated poly(ether sulfone) (SPES). The morphology, tensile strength, proton conductivity and methanol permeability of the blend membranes were investigated.

Sulfonated poly(ether sulfone)/sulfonated polybenzimidazole blend membrane for fuel cell applications

European Polymer Journal, 2010
Abstract Polymer blending is used to modify or improve the dimensional and thermal stability of any two different polymers or copolymers. In this study, both sulfonated polybenzimidazole homopolymer (MS-p-PBI 100) and sulfonated poly(aryl ether benzimidazole) copolymers (MS-p-PBI 50, 60, 70, 80, 90) were successfully synthesized from commercially ...
