Levitz, Andrew published the artcileSynthesis and effect of heterocycle modification on the spectroscopic properties of a series of unsymmetrical trimethine cyanine dyes, Name: Sodium 3-bromopropane-1-sulfonate, the publication is Dyes and Pigments (2014), 238-249, database is CAplus.

Carbocyanine dyes are a class of organic compounds that contain two heterocycles that act as electron donors and acceptors connected by a conjugated methine bridge. Herein the synthesis of a series of 16 novel unsym. trimethine cyanine dyes is reported. Their structures were characterized by various spectroscopic techniques, and their optical properties were measured. Absorption maxima of the dyes were calculated using the time-dependent d.-functional theory method and the computational absorption maxima are consistent with the exptl. data. The addition of electron withdrawing substituents such as halogens on the heterocycle gave more favorable optical properties such as higher quantum yield and molar absorptivity. The aggregation of these cyanine dyes was studied and compared to a similar series of sym. cyanine dyes. It was determined that the heterocycle has more effect on aggregation than the side chain and a dye with two different heterocycles will aggregate less than a dye with the same heterocycle. The dyes were also investigated for Lipinski Rule violations as their use is becoming more prevalent for in vivo applications.

Qi, Zhigang published the artcileSynthesis and characterization of acid-base polyimides bearing pendant sulfoalkoxy groups for direct methanol fuel cell applications, Product Details of C3H6BrNaO3S, the publication is Journal of Applied Polymer Science (2015), 132(29), 42238/1-42238/8, database is CAplus.

A series of acid-base polyimides with sulfonic acid groups in the side chains have been prepared, based on a new synthesized sulfonated diamine monomer containing pyridine functional group. The effect of the introduction of pyridine groups into copolymer backbone on the properties of membrane were evaluated through the investigation of membrane parameters. The copolymers produced flexible, tough, and transparent membranes by solvent casting method. All the prepared membranes displayed high thermal stability, great oxidative stability and good mech. properties. They exhibited appropriate water uptake (15.8-30.2 wt % at 80°C) and remarkable dimensional stability (2.5-6.9% at 80°C). The proton conductivity of SPI-80 was 1.01 × 10^-2 S cm^-1 at room temperature Moreover, the methanol permeability of SPI-80 membrane was 1.22 × 10^-7 cm² s^-1, which was lower than 23.8 × 10^-7 cm² s^-1 of Nafion 117. Therefore, these acid-base polyimides materials have a promising prospect for direct methanol fuel cell applications. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42238.

Preston, Adam J. published the artcileSynthesis and Selected Reactions of a Bicyclic Sultam Having Sulfur at the Apex Position, Safety of Sodium 3-bromopropane-1-sulfonate, the publication is Journal of Organic Chemistry (2006), 71(17), 6573-6578, database is CAplus and MEDLINE.

A practical synthesis of the bicyclic dienyl sultam I has been developed. The viable route involved several key steps. Of these, ring-closing metathesis, represented by the conversion of II to III, had to be implemented in advance of the assembly of other rings such as is present in IV. The second double bond was best introduced by a bromination-dehydrobromination sequence, the 2-fold loss of HBr being achieved most reliably by the use of tetra-n-butylammonium fluoride in CH₂Cl₂ or DMSO. The direct irradiation of I gave rise to the endo-oriented cyclobutene derivative V. The title diene is not a ready participant in Diels-Alder reactions. When heated with endo-bornyltriazolinedione in Et acetate solution, conversion to a 1:1 mixture of VI and its diastereomer occurred as confirmed by X-ray crystallog. anal. From the mechanistic perspective, this transformation constitutes an interesting example of a stereocontrolled and regioselective [2+2] cycloaddition followed by a vinylcyclobutane-cyclohexene rearrangement. Products V and VI constitute examples of strained sulfonamides featuring a norbornyl-like structural component.

Yin, Yan published the artcileSynthesis and properties of highly sulfonated proton conducting polyimides from bis(3-sulfopropoxy)benzidine diamines, Related Products of bromides-buliding-blocks, the publication is Journal of Materials Chemistry (2004), 14(6), 1062-1070, database is CAplus.

Two novel sulfonated diamine isomers, 2,2′-bis(3-sulfopropoxy)benzidine (2,2′-BSPB) and 3,3′-bis(3-sulfopropoxy)benzidine (3,3′-BSPB), were successfully synthesized and the highly sulfonated polyimides (SPIs) with sulfonic acid groups in the side chains were prepared from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA) and BSPB monomers. Transmission electron microscopy (TEM) anal. revealed that these side-chain-type SPI membranes have a microphase-separated structure composed of hydrophilic side chain domains and hydrophobic polyimide main chain domains. They showed high proton conductivities similar to or higher than those of Nafion 117 in the high relative humidity range (>70% RH). The proton conducting behavior was analyzed by percolation theory. Despite their high ion exchange capacity (IEC = 2.89 meq. g^-1) and high water uptakes, they displayed much better water stability than common sulfonated polyimides with the sulfonic acid groups directly bonded to the polymer backbone. This is probably due to the microphase-separated structure of the membrane and the strong basicity of BSPB diamine moieties resulting from the electron donating effect of the propoxy groups. The sulfopropoxy groups were stable against aging in acidic aqueous solution at 373 K. Both the polyimide membranes showed good mech. strength under high moisture conditions (about 6 GPa at 90% RH) and displayed anisotropic membrane swelling.

Yin, Yan published the artcileSynthesis, proton conductivity and methanol permeability of a novel sulfonated polyimide from 3-(2′,4′-diaminophenoxy)propane sulfonic acid, HPLC of Formula: 55788-44-8, the publication is Polymer (2003), 44(16), 4509-4518, database is CAplus.

A novel sulfonated diamine monomer, 3-(2′,4′-diaminophenoxy)propane sulfonic acid (DAPPS), was successfully synthesized and the sulfonated polyimide (SPI) was prepared from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA) and DAPPS. The resulting SPI, NTDA-DAPPS, was soluble in common organic solvents. The SPI membrane displayed proton conductivity σ values of 0.12-0.35 S/cm at temperatures ranging from 35 to 90 °C in liquid water, which were similar to or higher than those of Nafion 117 and sulfonated hydrocarbon polymers. The σ of the SPI membrane decreased significantly with decreasing relative humidity (RH) and became much lower than that of Nafion 117 at 30% RH. The SPI membrane displayed good water stability at 80 °C and was thermally stable up to 240 °C. It showed reasonable mech. strength of a modulus of 1.3 GPa at 90 °C and 90% RH. Its methanol permeability P_M was 0.57×10^-6 cm²/s at 30 °C and 8.6 wt% methanol in feed, which was a fourth of that of Nafion 117. As a result, its ratio of σ/P_M was 21×10⁴ S cm^-3 s, which was about 4 times larger than that of Nafion 117, suggesting potential application of the SPI membrane for direct methanol fuel cell.
