In 2016,Zhang, Wei; Tan, Yue Hua; Finch, James A. published 《Synthesis and characterization of alkyl, propoxy, ethoxy-based frothers》.Minerals Engineering published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

In this paper the authors describe the synthesis and characterization of a homologous series of linear polyglycol-based frothers comprising alkyl, propoxy (propylene oxide, PO), and ethoxy (ethylene oxide, EO) groups. The identities were confirmed by proton NMR spectroscopy and total organic carbon anal. Characterization used three parameters, bubble size, gas holdup and water overflow rate, measured in a bubble column. The results indicate that increasing number of PO groups led to significant decrease in bubble size, and increase in gas holdup and water overflow rate. Increasing the alkyl chain length, gave similar but less pronounced trends; the least effect was increasing the number of EO groups. Changing the relative position of the PO and EO group had a significant effect on all three parameters. To account for the effect of PO/EO position, a mechanism based on effect of structure on mol. packing at the air/water interface is proposed. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Safety of 1,2-Diiodoethane) was used in this study.

Hyeok published 《Bis-imidazolium iodide organic ionic plastic crystals and their applications to solid state dye-sensitized solar cells》.Organic Electronics published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

Novel dicationic bis-imidazolium iodide salts have been discovered as new organic ionic plastic crystalline materials. Most of them show multiple solid-solid phase transitions below their melting temperatures Their phase transition temperatures are dependent on the imidazolium cation structure. According to Timmermans’ definition of plastic crystals, bis-imidazolium iodide salts with either n-heptyl or n-octyl side arms can be classified as “”true plastic crystals”” because of their low ΔSf values (<20 J mol-1 K-1). The bis-imidazolium iodide salts are stable up to 260°C under thermal gravimetric anal. The ionic conductivities, investigated using dielec. relaxation spectroscopy, follow the Arrhenius temperature dependence with discontinuities and changes in slopes at the observed solid-solid phase transition temperature Dye-sensitized solar cells (DSSCs) fabricated by a whole solid-state electrolyte consisting of n-hexyl side-armed bis-imidazolium iodide (BII-6) show a 4.93% power conversion efficiency (η): a remarkable result for the solid-state electrolyte system compared to that obtained using an liquid electrolyte with 1-butyl-3-methylimidazolium iodide (η = 8.00%) as a reference composition1,2-Diiodoethane(cas: 624-73-7Safety of 1,2-Diiodoethane) was used in this study.

Two iodinated (1 and 2) and two brominated (3 and 4) BODIPY-based photosensitizers are prepared and characterized using slightly modified synthetic procedures previously described. 1-4 present intense absorption bands in the 510-540 nm interval and very weak emissions due to the presence of halogen atoms in their structure. Irradiation of aqueous solutions of 1-4 with visible light (wavelength > 475 nm) induce the generation of singlet oxygen with quantum yields of ca. 0.62-0.66 for the photosensitizers containing iodine atoms (1 and 2) and of ca. 0.16-0.21 for the brominated counterparts (3 and 4). In vitro studies carried out with HeLa, SCC-13 and HaCaT cell lines and the four photosensitizers show marked reductions in cell viability with lower IC50 values for the iodinated derivatives (in the 0.82-2.51 range) than those found for the brominated compounds (in the 0.91-8.26 range) suggesting that these compounds could be used in photodynamic therapy protocols. Subcellular localization studies carried out using confocal microscopy show that photosensitizers accumulated in the endoplasmic reticulum.1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Related Products of 516-12-1) was used in this study.

And the article was published in ChemElectroChem in 2019. Formula: C7H5IO2 The author mentioned the following in the article:

Hypervalent iodine compounds constitute a popular class of reagents in organic chem. Regardless of whether they are generated in situ from an iodoarene precursor with a terminal oxidant or used in stoichiometric amounts, the resulting separation and waste issues are major challenges en route to sustainable and scalable processes. The electrochem. generation of iodine(III) compounds represents an attractive alternative, since elec. current is used as traceless oxidant and unstable or hazardous species are conveniently generated in situ. In this context, we have explored the possibility for the use of iodoarene sulfonates and iodobenzoates as ex-cell mediators for electrosynthesis in 1,1,1,3,3,3-hexafluoroisopropanol. While 2-, 3- and 4-iodobenzoate salts proved to be impractical for various reasons, 2- and 4-iodobenzenesulfonates salts can be selectively oxidized to the iodine(III) species and used for synthetic applications. The ionic tag on the mediator allows for electrolysis without supporting electrolyte additives and enables a straightforward recovery from the product mixture The experimental process involved the reaction of 2-Iodobenzoic acid(cas: 88-67-5Formula: C7H5IO2)

And the article was published in Chemical Science in 2019. Reference of 1-Iodopyrrolidine-2,5-dione The author mentioned the following in the article:

Efficient triplet photosensitizers are important for fundamental photochem. studies and applications such as triplet-triplet annihilation upconversion (TTA UC), photoredox catalytic organic reactions and photovoltaics. We now report a series of phosphorus corrole compounds as efficient visible light-harvesting metal-free triplet photosensitizers. While the heavy-atom-free phosphorus corroles show absorption in the visible spectral region (centered at 573 nm) and have a decent triplet state quantum yield (ΦΔ = 49%), iodo-substitution on the corrole core induces red-shifted absorption (589 nm) and improves intersystem crossing significantly (ΦΔ = 67%). Nanosecond transient absorption spectra confirm triplet state formation upon photoexcitation (τT = 312 μs) and the iodinated derivatives also display near IR phosphorescence in fluid solution at room temperature (λem = 796 nm, τp = 412 μs). Both singlet oxygen (1O2) and superoxide radical anions (O2- ·) may be produced with the phosphorus corroles, which are competent photocatalysts for the oxidative coupling of benzylamine (the Aza Henry reaction). Very efficient TTA UC was observed with the phosphorus corroles as triplet photosensitizers and perylene as the triplet acceptor, with upconversion quantum yields of up to ΦUC = 38.9% (a factor of 2 was used in the equation) and a very large anti-Stokes effect of 0.5 eV.
