And the article contained the following:

Several polycrystalline mols. with sulfonate groups and some of their metal complexes, including DL-homocysteic acid (DLH) and its Sr- and Cu-complexes, pyridine-3-sulfonic acid and its Co- and Ni-complexes, sulfanilic acid and -cysteic acid were studied using THz time-domain methods at room temperature The results of THz absorption spectra show that the mols. have characteristic bands at 0.2-2.7 THz (6-90 cm-1). THz technique can be used to distinguish different mols. with sulfonate groups and to determine the bonding of metal ions and the changes of H bond networks. In the THz region DLH has three bands: 1.61, 1.93 and 2.02 THz; and 0.85, 1.23 and 1.73 THz for Sr-DLH complex, 1.94 THz for Cu-DLH complex, resp. The absorption bands of pyridine-3-sulfonic acid are located at 0.81, 1.66 and 2.34 THz; the bands at 0.96, 1.70 and 2.38 THz for its Co-complex, 0.76, 1.26 and 1.87 THz for its Ni-complex. Sulfanilic acid has three bands: 0.97, 1.46 and 2.05 THz; and the absorption bands of -cysteic acid are at 0.82, 1.62, 1.87 and 2.07 THz, resp. The THz absorption spectra after complexation are different from the ligands, which indicate the bonding of metal ions and the changes of H bond networks. M-O and other vibrations appear in the FIR region for those metal-ligand complexes. The bands in the THz region were assigned to the rocking, torsion, rotation, wagging and other modes of different groups in the mols. Preliminary assignments of the bands were carried out using Gaussian program calculation The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Safety of Pyridine-3-sulfonic acid

On February 4, 2005, Yamada, Masanori; Honma, Itaru published an article.Formula: C5H5NO3S The title of the article was Proton conductivity of zwitterionic-type molecular solids under intermediate temperature and anhydrous conditions. And the article contained the following:

Anhydrous proton conducting material for polymer electrolyte membrane fuel cell (PEFC) was prepared by the mixing of zwitterionic-type mol. solid 3-pyridinesulfonic acid (PS) and organic acid methylenediphosphonic acid (MP). As a result, PS mol., which has a sulfonic acid and a pyridine group in its structure, showed the proton conductivity of 4 × 10-5 S cm-1 at 160°C under anhydrous condition. Surprisingly, by the mixing of MP to PS material, the PS-MP composite material exhibited a conductivity of 2 × 10-3 S cm-1. Also, the conductivity of PS-MP composite material did not decrease under the heating at 160° for 50 h. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Formula: C5H5NO3S

On January 6, 2020, Liu, Shan-Shan; Han, Zhen; Yang, Jin-Sen; Huang, Sheng-Zheng; Dong, Xi-Yan; Zang, Shuang-Quan published an article.Electric Literature of 636-73-7 The title of the article was Sulfonic Groups Lined along Channels of Metal-Organic Frameworks (MOFs) for Super-Proton Conductor. And the article contained the following:

Designing high-performance proton-conducting metal-organic frameworks simultaneously having highly hydrothermal stability and a high-d. proton carrier remains a great challenge. Fe-MIL-88B is a classic metal-organic framework (MOF) with a large-size one-dimensional (1D) channel lined with a high-d. uncoordinated metal atom for postfunctionalization; however this MOF cannot act as a proton conductor due to the weak hydrothermal stability. Here, we prepared an ultrastable isostructure Cr-MIL-88B, which is subsequently functionalized by anchoring 3-pyridinesulfonic acid and 2-(4-pyridyl) ethanesulfonic acid on the naked Cr atoms exposed on the surface of the host-framework, producing two new MOFs, i.e. Cr-MIL-88B-pyridine sulfonic acid (abbreviated as Cr-MIL-88B-PSA) and Cr-MIL-88B-pyridine ethanesulfonic acid (abbreviated as Cr-MIL-88B-PESA). Thus, Cr atoms on the host framework were modified by functional sulfonic groups, which stick out toward the center of the channel forming ordered high-d. sulfonic groups as proton donors along the open channel and achieving the highest proton conductivity of 4.50 × 10-2 S cm-1 for Cr-MIL-88B-PESA and 1.58 × 10-1 S cm-1 for Cr-MIL-88B-PSA, surpassing that of the Nafion membrane. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Electric Literature of 636-73-7

On December 15, 2018, Han, Fei; Tu, Zeyi; Wan, Zhongquan; Luo, Junsheng; Xia, Jianxing; Hao, Guimin; Yi, Yuanping; Wang, Ruilin; Jia, Chunyang published an article.Reference of Pyridine-3-sulfonic acid The title of the article was Effect of functional group position change of pyridinesulfonic acid as interface-modified layer on perovskite solar cell. And the article contained the following:

There are fewer researches on the effect of functional group position change on device performance for highly efficient perovskite solar cell. In this work, we take pyridinesulfonic acid as an example, and study the effect of the isomeride: 2- and 3-pyridinesulfonic acid self-assembled monolayer on device performance for highly efficient perovskite solar cell. The efficiency of control device is 14.65% (Hysteresis Index = 0.31) under illumination of a simulated sunlight (AM 1.5G, 100 mW cm-2). Through use of the 3-pyridinesulfonic acid self-assembled monolayer, the device exhibits striking improvements to reach the efficiency of 16.88% (Hysteresis Index = 0.02), which constitutes an enhancement compared to those of 2-pyridinesulfonic acid self-assembled monolayer modified device (16.54%, Hysteresis Index = 0.02). The enhanced photovoltaic performances can be attributed to the larger perovskite grain sizes, and easier passivation of electron transporting layer/perovskite interface, which promote the charge separation, transport and collection. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Reference of Pyridine-3-sulfonic acid

And the article contained the following:

The effects of bath composition on the internal stress of palladium electrodeposits are studied in neutral media with Pd(NH3)2Cl2, K3C6H5O7, (NH4)2C2O4 and the additives of the mixture of the synthesized products of nicotinic acid and nicotiamide (NANA), pyridine-3-sulfonic acid (PSA), α-furan formic acid (FF) and cetyl tri-Me ammonium bromide (CTMAB).

The phase-transition behaviors, crystal structures, and dielec. properties of four kinds of simple 1:1 organic salts of (C12H25NH3+)(benzenesulfonate) and (C12H25NH3+)(pyridine sulfonates) were examined from the viewpoint of intermol. hydrogen-bonding interactions and dynamic conformational transformation in mol. assemblies. Crystals of (C12H25NH3+)(benzenesulfonate) and (C12H25NH3+)(3-pyridinesulfonate) were isostructural and solid-solid and solid-liquid-crystal smectic A (SmA) phase transitions were observed These two crystals formed rodlike cation-anion assemblies. However, the two salts, (C12H25NH3+)(2-pyridinesulfonate) and (C12H25NH3+)(4-pyridinesulfonate), formed largely bent L-shaped cation-anion conformations. Interesting conformational transformations from rodlike to L-shaped assemblies were observed in (C12H25NH3+)(2-pyridinesulfonate) and (C12H25NH3+)(3-pyridinesulfonate).
