The effect of the number, position, and shape of methoxy groups in triphenylamine donors on the performance of dye-sensitized solar cells was written by Kim, Se Hun;Choi, Jun;Sakong, Chun;Namgoong, Jin Woong;Lee, Woosung;Kim, Dong Hoe;Kim, Boeun;Ko, Min Jae;Kim, Jae Pil. And the article was included in Dyes and Pigments in 2015.Electric Literature of C8H9IO2 This article mentions the following:

Four new organic photosensitizers (SH-11閳?4) that introduced methoxy groups as an addnl. donor were synthesized, and used in dye-sensitized solar cells. The dyes were designed in order to investigate the effects on the dye photophys. properties and the cell photovoltaic performance, by the number, position, and shape of methoxy groups introduced at the para-/ortho- and para-/meta- and para-(open or closed ring shape) positions on the triphenylamine donor. The introduction of methoxy groups led to bathochromic shift of the absorption spectrum, and enhancement of the molar extinction coefficient of the dyes. Their introduction decreased the amount of dye adsorbed on TiO₂ surface, due to the increased steric hindrance. As their number increased, an open-circuit voltage value decreased. All things considered, the dye (SH-14) with closed ring shape shows the best conversion efficiency of 6.01% under AM 1.5G conditions (N719 dye’s 7.59% under the same conditions). In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Electric Literature of C8H9IO2).

4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. 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.Electric Literature of C8H9IO2

And the article was included in Organic Letters in 2019.Recommanded Product: 1-Bromo-4-(2-iodoethyl)benzene This article mentions the following:

The authors describe an operationally simple transition-metal-free borylation of alkyl iodides. This method uses com. available diboron reagents as the B source and exhibits excellent functional group compatibility. Also, a diverse range of primary and secondary alkyl iodides could be effectively transformed to the corresponding alkylboronates in excellent yield. Mechanistic studies suggest that this borylation reaction proceeds through a single-electron transfer mechanism featuring the generation of an alkyl radical intermediate. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-(2-iodoethyl)benzene (cas: 85356-68-9Recommanded Product: 1-Bromo-4-(2-iodoethyl)benzene).

1-Bromo-4-(2-iodoethyl)benzene (cas: 85356-68-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Recommanded Product: 1-Bromo-4-(2-iodoethyl)benzene

Spanik, Ivan published the artcileGC separation of 2-substituted ethyl propionate enantiomers on permethylated and 2,6-dimethyl-3-pentyl β- and γ-cyclodextrin stationary phases, COA of Formula: C5H9IO2, the publication is Journal of Separation Science (2005), 28(12), 1347-1356, database is CAplus and MEDLINE.

The capillary gas chromatog. enantiomer separation of eight congeneric compounds CH₃-HCX-COOC₂H₅ (X = Cl, Br, I, CN, OH, OC₂H₅, OC₆H₅ and NHCOCF₃) on four different permethyl- and 2,6-di-O-methyl-3-O-pentyl- β- and γ-CD stationary phases was studied. The separation of enantiomers was evaluated in terms of the interactions of the X substituent of studied derivatives, as well as the nature of the 3-O-alkyl group in the 2,6-di-O-methyl-3-O-alkyl-CDs and the CDs cavity size. The differences in thermodn. data [ΔH and -ΔS] obtained for studied compounds and the selectivity of modified β- and γ-cyclodextrin phases in gas chromatog. separation were evaluated. ΔH values were compared with a ΔH value of an achiral standard (Et propionate, where X = H) to obtain the contribution of a particular substituent to the overall interaction energy. The variation in the enantiomeric separation with temperature and the retention order of these compounds on a given cyclodextrin capillary column depends on the nature of the substituents bonded to stereogenic carbon atom. The temperature dependencies of selectivity factors, In α on 1/T, were both linear as well as nonlinear, inter alia depending on the number of glucopyranose units of the CD derivatives The enantiospecific thermodn. data [Δ₂₁(ΔH)] and [-Δ₂₁(ΔS)] which characterize the chiral recognition in the separation system were used to gain more insight into the mechanistic aspects of the enantioseparations on permethylated and 2,6-di-O-methyl-3-O-pentyl-β- and γ-cyclodextrins.

Shelkovnikov, V. V. published the artcileOptical and nonlinear-optical properties of pseudoisocyanine J-aggregates with the controlled exciton absorption linewidth, Application In Synthesis of 606-55-3, the publication is High Energy Chemistry (Translation of Khimiya Vysokikh Energii) (2002), 36(4), 260-264, database is CAplus.

Thin films of mol. J-aggregates of pseudoisocyanine with different linewidths of exciton absorption (from 75 to 210 cm^-1) were obtained. A change in the absorption linewidth of J-aggregates was achieved by introducing organic salts into a sample. As an alternative method of varying the exciton absorption linewidth, variation in sample temperature was used. For the samples obtained, the 3rd-order nonlinear optical susceptibility χ⁽³⁾ was measured at temperatures of 80 and 293 K by the Z scan and pump-probe spectroscopy techniques and the dependence of χ⁽³⁾ on the absorption linewidth W was found to follow a power law. The character of the function χ⁽³⁾(W) is almost independent of the method for measuring the absorption linewidth to have the form χ⁽³⁾ approx. W^δ with δ ≈ -(1.36-1.58). Based on this finding, the relation of the exciton delocalization length in the aggregate to the absorption linewidth and optical nonlinearity is discussed.

Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II). So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about How does the ligands structure surrounding metal-N4 of Co-based macrocyclic compounds affect electrochemical reduction of CO2 performance?.

Metal-Nx-C based materials have emerged as one of the most promising electrocatalysts for electrochem. reduction of CO2 (ERCD). Co-based macrocyclic compounds showed unique performance, however, of which the relation between the ligands structure surrounding Co-N4 centers and reaction mechanism remains vague. To explore this issue, here, Co-based macrocyclic compounds are elaborately chosen as model catalysts, including phthalocyanine Co (CoPc), Co (II) meso-Tetraphenylporphine (CoTp) and Co tetramethoxyphenylporphyrin (CoTop), which possess well-defined Co-N4 coordinated centers but different ligands structure surrounding Co-N4. Electrochem. measurements show that CoPc possesses higher activity and selectivity for CO with faradaic efficiency (FE) >62% at -0.7 V (vs. RHE) relative to those of CoTp and CoTop. Combining d. functional theory (DFT) calculations, further CoPc is more favorable for ERCD to CO due to the rapid formation of key intermediate COOH* and the desorption of CO, demonstrating that the structure of ligands (phthalocyanine) surrounding Co-N4 plays a crucial role in the high CO selectivity. It can be anticipated that an exclusive strategy will pave a new avenue for further understanding the ERCD mechanism of Co-Nx-C catalysts.

After consulting a lot of data, we found that this compound(28903-71-1)Name: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II) can be used in many types of reactions. And in most cases, this compound has more advantages.
