All-visible-light controlled fluorescence switching is more promising for bioimaging. Constructing dual-color fluorescent bisthienylethene (BTE) systems are quite challenging. Here, all-visible-light triggered dual-color fluorescence switching was achieved in a color-specific switching manner in a solid-state by associating the photochromic BTE core with a blue emissive phenanthroimidazole (PI) unit. Unique emission behavior caused by J-aggregation of the coplanar PI unit was crucial, which suggested a novel strategy for constructing dual-color fluorescent photoswitching. Moreover, a ‘turn-off’ fluorescence photoswitching was demonstrated in solution and PMMA films owing to the energy transfer from the PI moiety to a ring-closed isomer of the BTE moiety. Remarkably, an all-visible-light patterning application for information storage medium was developed with these compounds BTE-P1 was successfully utilized in cellular imaging for efficient fluorescence switching.

Zheng, Kewang published the artcileAdsorption of Cu²⁺ by modified chitosan microspheres and its application in homocoupling of arylboronic acid, Synthetic Route of 145349-62-8, the publication is Arabian Journal of Chemistry (2022), 15(10), 104170, database is CAplus.

The modified chitosan microspheres were first prepared by emulsification and investigated the performance of the chitosan adsorbent for the adsorption of copper ions. The catalytic performance of chitosan-supported copper microspheres in the self-coupling of arylboronic acids using 4-methoxybenzene as the model substrate was evaluated, while exploring a wide range of substrates including aryl boronic acid derivatives and heterocyclic arylboronic acids, including aldehyde, nitro, and aldehyde groups. The exptl. results show that good to excellent yields (55%-95%) of the desired dimer products were obtained under mild conditions at room temperature and in air, and the catalytic material could be reused up to five times with no significant decrease in catalytic activity.

Reaction of MnCl₂ and 2-dimethylaminoisopropyl chloride hydrochloride afforded one novel mol.-based material, (C₅H₁₃ClN)₂[MnCl₄] (1). And it is interesting to note that 1 exhibits intense greenish fluorescent emission (520 nm) at room temperature and relatively high thermal stability (stable up to 450 K). Moreover, structure and spectra analyses reveal that its excellent optical property can be attributed to the ⁴T₁ (G) → ⁶A₁ electronic transition of Mn²⁺ in [MnX₄]^2- tetrahedron.

The photoswitching of photochromic bisthienylethene mixed electron donor-π-accepter (2D-π-A) type fluorescent dye with appropriate doping ratio was constructed, which showed excellent fluorescence switch “on” and “off” when the photochromic bisthienylethene undergoes ring-opening and ring-closed photoisomerization with UV and visible-light irradiation in solution and PMMA film. The erasable and rewritable photoimages on the photochromic bisthienylethene mixed 2D-π-A type fluorescent dye in PMMA were successfully demonstrated, which will provide a simple and viable method for optical data storage based photochromic fluorescent materials.

The simultaneous control of diastereoselectivity and regioselectivity in Zn-catalyzed allenylation reactions of N-protected L-α-amino aldehydes is reported. A reversal in diastereoselectivity could be realized by variation of the α-amino aldehyde protecting groups. A range of 1-allenyl-2-amino alcs. were obtained with excellent regioselectivity and converted to oxazolidinones and dihydrofurans. Many oxazolidinones and dihydrofuran could be isolated as single diastereoisomers and without significant erosion of ee, making this a practical catalytic synthesis of highly functionalized heterocycles.

Yakubenko, Artyom A. published the artcileSelf-association of diphenylpnictoginic acids in solution and solid state: covalent vs. hydrogen bonding, Quality Control of 7080-50-4, the publication is Physical Chemistry Chemical Physics (2022), 24(13), 7882-7892, database is CAplus and MEDLINE.

Triphenylpnictogens were oxidized to access diphenylpnictioginic acids Ph₂XOOH (X = P, As, Sb, Bi). Oxidation with chloramine-T does not lead to the cleavage of a C-pnictogen bond. The preliminary reductive cleavage with sodium in liquid ammonia followed by the oxidation with hydrogen peroxide was successfully used for the synthesis of diphenylphosphinic and diphenylarsinic acids. In solid state (by XRD), all diphenylpnictoginic acids form polymeric chains. Diphenylbismuthinic and diphenylantimonic acids form polymeric covalent adducts, while diphenylphosphinic and diphenylarsinic chains are associated through hydrogen bonding. Unlike diphenylphosphinic acid, diphenilarsinic acid forms two polymorphs of hydrogen-bonded infinite chains. In solution in a polar aprotic solvent diphenylarsinic acid, similarly to dimethylarsinic, forms hydrogen-bonded cyclic dimers together with a small amount of cyclic trimers.

Seth, Kapileswar published the artcileCooperative Catalysis by Palladium-Nickel Binary Nanocluster for Suzuki-Miyaura Reaction of Ortho-Heterocycle-Tethered Sterically Hindered Aryl Bromides, SDS of cas: 480438-56-0, the publication is Organic Letters (2014), 16(9), 2334-2337, database is CAplus and MEDLINE.

The palladium-nickel binary nanocluster is reported as a new catalyst system for Suzuki-Miyaura cross-coupling of ortho-heterocycle-tethered sterically hindered aryl bromides. The inferior results obtained with the reported Pd/Ni salts/complexes or individual Pd/Ni nanoparticles as catalyst reveal the cooperative catalytic effect of the Pd and Ni nanoparticles in the Pd-Ni nanocluster. The broad substrate scope with respect to variation of the 2-arylbenzoxazole moiety and boronic acids, which offers a means for diversity generation and catalyst recyclability, marks a distinct advantage. E.g., in presence of palladium-nickel binary nanoclusters in DMF, Suzuki-Miyaura cross-coupling of PhB(OH)₂ with sterically hindered aryl bromide (I) gave 80% II.

Nelson, Peter J. published the artcileEffect of ascorbic acid deficiency on the in vivo synthesis of carnitine, Synthetic Route of 6249-56-5, the publication is Biochimica et Biophysica Acta, General Subjects (1981), 672(1), 123-7, database is CAplus and MEDLINE.

Guinea pig liver and kidney carnitine [541-15-1] levels were not affected by ascorbic acid [50-81-7] deficiency, but scorbutic animals had 50% less carnitine in heart and skeletal muscle than control animals. Labeled carnitine precursors, 6-N-trimethyl-L-lysine [23284-33-5] and 4-N-trimethylaminobutyrate [407-64-7], both of which require ascorbate for their enzymic hydroxylation, were injected into the vena cava of control, pair-fed and scorbutic animals. The uptake of trimethyllysine by the liver was <2% in 1 h, while the kidney took up ∼20% of the ¹⁴C. Control and pair-fed animals converted trimethyllysine to kidney trimethylaminobutyrate 8-10 times as well as did scorbutic animals. Trimethylaminobutyrate hydroxylase [56803-11-3], present in the liver but almost absent from the kidney, converted nearly all of substrate taken up by the liver to carnitine in both the scorbutic and control animals.
