A new 1-[2-methyl-5-(4-tetraphenylporphyrinphenyl)-3-thienyl]-2-[2-methyl-3-thienyl]-cyclopentene (DTE-TPP) combined by 3,3-(1-Cyclopentene-1,2-diyl)bis(5-chloro-2-methylthiophene) (DTE) and tetraphenylporphyrin (TPP) can transform between the open isomer and the closed isomer upon the irradiation of UV or visible light. Herein, they can be used to write binary data. Furthermore, the open form can emit luminescence but the closed cannot while irradiated in another light that cant cause optical chem. reactions. Therefore, the data can be read out without damage.

Jiang, Linhai published the artcileElaborate Supramolecular Architectures Formed by Co-Assembly of Metal Species and Peptoid Macrocycles, HPLC of Formula: 42074-68-0, the publication is Crystal Growth & Design (2021), 21(7), 3889-3901, database is CAplus.

Peptoids are a family of sequence-specific oligomers capable of mimicking the structure and function of polypeptides. The innate folding and self-assembly capabilities of peptoid oligomers can be enhanced by the presence of coordinated metal ions. The authors explore the co-assembly of water-soluble hexameric and tetrameric peptoid macrocycles with Na⁺ and K⁺ ions. Solid-state structures were solved for six cyclopeptoid-metal coassemblies by x-ray diffraction using single crystals grown from fully aqueous solutions Subtle variations in the peptoid oligomer composition give rise to dramatic alterations in the supramol. assemblies. Some structures feature extensively hydrated porous architectures that include unusual metal ion clusters. The ability to study the metallopeptoid structure at an at. resolution in crystals obtained from an aqueous solution is an important advancement, as most previous peptoid crystal structures were obtained from nonaqueous or cosolvent solutions These results will facilitate the design of peptoids and other foldamers for the assembly of supramol. frameworks.

Chou, Chun-Cheng published the artcile4,4′,5,5′-tetracarboxy-2,2′-bipyridine Ru(II) sensitizers for dye-sensitized solar cells, Category: chlorides-buliding-blocks, the publication is Inorganic Chemistry (2014), 53(16), 8593-8599, database is CAplus and MEDLINE.

Two Ru(II) sensitizers TCR-1 and TCR-2 bearing four carboxy anchoring groups were prepared using 4,4′,5,5′-tetraethoxycarbonyl-2,2′-bipyridine chelate and 4-(5-hexylthien-2-yl)-2-(3-trifluoromethyl-1H-pyrazol-5-yl)pyridine and 6-t-butyl-1-(3-trifluoromethyl-1H-pyrazol-5-yl)isoquinoline, resp. Dissolution of these sensitizers in DMF solution afforded a light green solution up to 10^-5 M, for which their color gradually turned red upon further dilution and deposition on the surface of a TiO₂ photoanode due to the spontaneous deprotonation of carboxylic acid groups. These sensitizers were characterized using electrochem. means and structural anal. time-dependent d. functional theory (TDDFT) simulation and were also subjected to actual device fabrication. The as-fabricated DSC devices showed overall efficiencies η = 6.16% and 6.23% vs. their 4,4′-dicarboxy counterparts TFRS-2 and TFRS-52 with higher efficiencies of 7.57% and 8.09%, using electrolyte with 0.2 M LiI additive. Their inferior efficiencies are possibly caused by the combination of blue-shifted absorption on TiO₂, inadequate dye loading, and the perpendicularly oriented central carboxy groups.

Li, Ziyong published the artcilePhoto-responsive [2]catenanes: synthesis and properties, COA of Formula: C15H14Cl2S2, the publication is Organic & Biomolecular Chemistry (2014), 12(39), 7702-7711, database is CAplus and MEDLINE.

A series of novel dithienylethene-based macrocycles containing ammonium moieties has been synthesized. They have been employed as templates to construct [2]catenanes showing their photoisomerization properties by means of a dynamic covalent chem. approach. Their structures have been reliably confirmed by NMR, ESI-MS or MALDI-QTOF-MS, and elemental anal., and their energy-minimized structures of open- and closed-ring isomers were investigated by the theor. calculation Investigation of the photochromic properties of these dithienylethene-based [2]catenanes has revealed good reversibility and excellent fatigue resistance upon irradiation with UV or visible light. Notably, formation of the [2]catenanes enhanced the photochromic properties compared with those of the corresponding macrocyclic ammonium salt, implying that the non-covalently interacting components of the [2]catenanes could affect the photoswitchable properties.

Ng, Wing-Hin published the artcileZwitterion-Catalyzed Intermolecular Bromoesterifications, Recommanded Product: Sodium chloro(tosyl)amide trihydrate, the publication is Organic Letters (2020), 22(14), 5572-5576, database is CAplus and MEDLINE.

Intermol. haloesterification is an important class of transformations. The resulting products are valuable building blocks. However, it is often necessary to use super-stoichiometric amount of acid in order to compensate the low reactivity. Herein, we report a zwitterion-catalyzed intermol. bromoesterification using acid and olefin in an equimolar ratio. Mechanistic study revealed that the charge pair in the zwitterion works synergistically in activating both NBS and carboxylic acid.

RP(O)(OSiMe3)2. Similar dealkylation of I (R = Cl3C, R1 = Et) at 61-9° for 2.7 h gave ≥99% Cl3CP(O)(OSiMe3)2. Dealkylations with Me3SiCl required higher temperatures and gave low yields.

Bis(imino nitroxide) bridged by a diarylethene annulated isomer was synthesized and the exchange interaction between the two radicals was determined by the simulation of the ESR spectrum. The exchange interaction was found to be as large as that of the closed-ring isomer, suggesting that the annulated isomer can be used as a highly-conductive mol. wire in mol. electronics.

Nine (C2-18) dialkyl trichloromethylphosphonates (TCMP) were synthesized by the Arbusov reaction from the corresponding trialkyl phosphite and CCl4. The reaction of (EtO)3P and CCl4 using daylight was completed in about 4 hr. However, in the preparation of the higher dialkyl TCMP the mixture of (RO)3P and CCl4 had to be refluxed 8 hr or more. These compounds were effective chelating, antistatic and flame resistant additives in a formulation of poly(vinyl chloride) as well as excellent extreme pressure additives for lubricating oil; especially the dibutyl TCMP which was effective at 0.25%.
