Dye dependent regeneration dynamics in dye sensitized nanocrystalline solar cells: Evidence for the formation of a ruthenium bipyridyl cation/iodide intermediate

We report a transient absorption study of the kinetics of re-reduction of ruthenium bipyridyl dye cations adsorbed to nanocrystalline TiO2 films by iodide ions, employing a series of Ru-II(dcbpy)(2)X dyes, where dcpby = 4,4′-dicarboxy-2,2′-bipyridyl and X = (NCS)(2), (CN)(2), DTC (diethyldithiocarbamate), and Cl-2. The data indicate that this re-reduction (or ‘regeneration’) reaction proceeds via a transient (dye(+)-iodide) intermediate complex formed by reaction of photogenerated dye cations with one iodide ion. The subsequent reaction of this complex with a second iodide ion, forming I-2(-), is shown to be the kinetically and thermodynamically limiting step in the overall regeneration reaction. The implications of this reaction scheme for the function of dye sensitized photoelectrochemical cells are discussed, considering in particular the high photovoltaic efficiencies obtained for such devices employing such ruthenium bipyridyl senstiser dyes in combination with iodide/tri-iodide based redox electrolytes.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 455-13-0, in my other articles.

Growth Stimulation of Iodide-Oxidizing alpha-Proteobacteria in Iodide-Rich Environments

alpha-Proteobacteria that can oxidize iodide (I-) to molecular iodine (I-2) have only been isolated from iodide-rich natural and artificial environments, i.e., natural gas brine waters and seawaters supplemented with iodide, respectively. To understand the growth characteristics of such iodide-oxidizing bacteria (IOB) under iodide-rich environments, microcosms comprising natural seawater and 1 mM iodide were prepared, and the succession of microbial communities was monitored by culture-independent techniques. PCR-denaturing gradient gel electrophoresis and 16S rRNA gene sequence analysis showed that bacteria closely related with known IOB were predominant in the microcosms after several weeks of incubation. Quantitative PCR analysis targeting specific 16S rRNA gene regions of IOB showed that the relative abundance of IOB in the microcosms was 6-76% of the total bacterial population, whereas that in natural seawater was less than 1%. When 10(3) cells mL(-1) of IOB were inoculated into natural seawater supplemented with 0.1-1 mM iodide, significant growth (cell densities, 10(5)-10(6) cells mL-1) and I-2 production (6-32 mu M) were observed. Interestingly, similar growth stimulation occurred when 12-44 mu M of I-2 was added to seawater, instead of iodide. IOB were found to be more I-2 tolerant than the other heterotrophic bacteria in seawater. These results suggest that I-2 plays a key role in the growth stimulation of IOB in seawater. IOB could potentially attack other bacteria with I-2 to occupy their ecological niche in iodide-rich environments.

Adding some certain compound to certain chemical reactions, such as: 455-13-0, name is 4-Iodobenzotrifluoride, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 455-13-0. 455-13-0

General procedure: In a 10 mL glass tube was placed 4-iodotoluene (219 mg, 1 mmol), potassium thiocyanate (243 mg, 2.5 mmol), copper(I) oxide (43 mg, 0.3 mmol), tetrabutylammonium bromide (97 mg, 0.3 mmol), and water (1 mL). The mixture was stirred for 1 min before sealing the tube with a septum and placing the reaction mixture into the microwave cavity (CEM Discover). An initial microwave power of 150 W was used, the temperature being ramped from rt to 200 C where it was held for 60 min (caution: The water is heated well above its boiling point so all necessary precautions should be taken when performing such experiments. Vessels designed to withhold elevated pressures must be used. The microwave apparatus used here incorporates a protective metal cage around the microwave vessel in case of explosion. After completion of an experiment, the vessel must be allowed to cool to a temperature below the boiling point of the solvent before removal from the microwave cavity and opening to the atmosphere.). The reaction mixture was stirred continuously throughout. The reaction was run in triplicate. After allowing the three identical reaction mixtures to cool to rt, the vessels were opened and their contents poured into a separatory funnel and the tubes washed three times with ethyl acetate (approximately 3 mL each time) followed by two washes with water (5 mL each time). All washings were added to the separatory funnel along with an additional 20 mL of ethyl acetate. Typically an emulsion was formed after shaking; therefore brine (approximately 5 mL) was added to aid separation. The aqueous layer was extracted twice more with ethyl acetate (approximately 30 mL each time). The organic washings were combined, washed with deionized water (approximately 20 mL), collected, dried over MgSO4, and then the ethyl acetate removed in vacuo. Purification was accomplished by column chromatography (100% hexanes) affording the product as a white solid (152 mg, 48%).

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4-Iodobenzotrifluoride.
