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. In the experimental materials used by the author, we found 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Reference of 1-Iodopyrrolidine-2,5-dione)

The author of 《Iodophenylsulfonates and iodobenzoates as redox-active supporting electrolytes for electrosynthesis》 were Roesel, Arend F.; Broese, Timo; Majek, Michal; Francke, Robert. 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)

2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Formula: C7H5IO2

And the article was published in Dyes and Pigments in 2019. Related Products of 516-12-1 The author mentioned the following in the article:

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.

The author of 《Diethynyldiazafluoren-9-ylidene as a π Cross-Conjugated Platform for Redox Active Transition Metal Fragments》 were Nauroozi, Djawed; Bruhn, Clemens; Faust, Ruediger. And the article was published in Organometallics in 2019. Recommanded Product: 1-Bromo-4-iodobenzene The author mentioned the following in the article:

Synthetic routes were developed to attach three redox-active metal fragments to cross-conjugated 3-methylidenepentadiyne covalently expanded by diazafluorenylidene: The two alkyne termini of this new ligand were end-capped via a phenylene spacer with ethynyl ferrocene, and a [Ru(bpy)2]2+ fragment was coordinated in the diimine binding site. The photophys. and electrochem. properties of both the diferrocenyl-terminated ligand and its corresponding Ru-complex were investigated by UV-vis absorption spectroscopy and cyclic voltammetry. The absorption data reveal significant interactions of the metal centers with the cross-conjugated ligand system. In the electrochem. experiments the ferrocenyl and the ruthenium centers could be addressed individually as they are separated by almost 1 V. While the presence of the Ru-fragment manifests itself in the reduction potential of the diazafluorenylidene-ligand, communication between the ferrocenyl end-caps on one hand and between the ferrocenes and the Ru-fragment on the other appears to be reduced through the freely rotating phenylene spacers. The results came from multiple reactions, including the reaction of 1-Bromo-4-iodobenzene(cas: 589-87-7Recommanded Product: 1-Bromo-4-iodobenzene)
