Zhu, Bang-Chang published the artcilep-Arsanilic acid stabilizing titanium-oxo clusters with various core structures and light absorption behaviours, Related Products of chlorides-buliding-blocks, the publication is Inorganic Chemistry Communications (2017), 14-17, database is CAplus.

P-Arsanilic acid stabilizing polyoxo-titanium clusters (PTCs) were successfully synthesized through solvothermal method, which present {Ti₄}, {Ti₅} and {Ti₆} cores functionalized by different carboxylic acid ligands. PTC-111 displays a {Ti₄} core structure which is stabilized by glycolic acid and esterified p-arsanilic acid. PTC-112, PTC-113 and PTC-114 have isostructural {Ti₆} structures, functionalized by isonicotinic acid, 2-chloroisonicotinic acid and HOBz, resp. The {Ti₅} core of PTC-115 is functionalized by m-nitrobenzoic acid. It is interesting that the light absorption behaviors of these PTCs are dependent on their core structures and the functionalizing ligands.

Calvo, Roxan published the artcileFacile access to nitroarenes and nitroheteroarenes using N-nitrosaccharin, Safety of Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Nature Communications (2019), 10(1), 1-8, database is CAplus and MEDLINE.

Nitroaroms. and nitroheteroaroms. serve as key building blocks and intermediates in synthesis, and form the core scaffold of a vast number of materials, dyes, explosives, agrochems. and pharmaceuticals. However, their synthesis relies on harsh methodologies involving excess mineral acids, which present a number of critical drawbacks in terms of functional group compatibility and environmental impact. Modern, alternative strategies still suffer from significant limitations in terms of practicality, and a general protocol amenable to the direct C-H functionalization of a broad range of aromatics has remained elusive. Herein, author introduces a bench-stable, inexpensive, easy to synthesize and recyclable nitrating reagent based on saccharin. This reagent acts as a controllable source of the nitronium ion, allowing mild and practical nitration of both arenes and heteroarenes displaying an exceptional functional group tolerance.

Li, Yan-Kai published the artcileThe magic of integration: Exploring the construction of dithienylethene-based infinite coordination polymers and their synergistic effect for gaseous ammonia probe applications, Synthetic Route of 219537-97-0, the publication is Chinese Chemical Letters (2016), 27(4), 518-522, database is CAplus.

Infinite coordination polymers are recognized as excellent platform for functionalization. Dithienylethene motifs, which are one of the most attractive functional moieties, were incorporated into an infinite coordination polymer, to deliver a smart porous material that can response to external stimuli. The obtained dithienylethene-based infinite coordination polymers (named Cu-DTEDBA) share the advantages of both infinite coordination polymers (porosity and stability) and dithienylethene motifs (photochromism). The phys. and chem. properties of Cu-DTEDBA were characterized by FTIR, TEM, SEM, XRD, TGA, UV-visible, EDX and BET. Also, the combination of dithienylethene and infinite coordination polymers gives rise to a synergistic effect, which induces functional behaviors of ammonia sensor applications. Both open and closed forms of Cu-DTEDBA exhibit distinct colorimetric change upon exposure to gaseous ammonia, which is not observed in dithienylethene free mols.

Zhang, Zhiwei published the artcileDiarylethenes with a Narrow Singlet-Triplet Energy Gap Sensitizer: a Simple Strategy for Efficient Visible-Light Photochromism, Name: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Advanced Optical Materials (2018), 6(6), n/a, database is CAplus.

All-organic visible-light photochromism is reported here via a novel strategy with narrow singlet-triplet energy gap (ΔE_ST) materials as a sensitizer. Taking advantage of the narrow ΔE_ST feature and the triplet-triplet energy transfer process, highly efficient photochromism of diarylethenes (DAEs) with both ring-open and ring-closure excitations shifted to visible light region is successfully achieved. Moreover, the wavelength of the visible excitation light can be easily modulated (e.g., from 405 to 470 nm) by elaborate selection of matched sensitized mols. The “write-and-erase” application of this photochromic system in polymer films is further demonstrated. This strategy provides a simple and versatile selection of well-matched DAE/sensitizer couples for visible-light photochromism without complicated mol. design.

Jin, Kunfeng published the artcileFacile Access to Solid-State Carbon Dots with High Luminescence Efficiency and Excellent Formability via Cellulose Derivative Coatings, Recommanded Product: 3-Carboxy-N,N,N-trimethylpropan-1-aminium chloride, the publication is ACS Sustainable Chemistry & Engineering (2020), 8(15), 5937-5945, database is CAplus.

Carbon dots (CDs), which are one kind of novel fluorescent materials, exhibit benign biocompatibility, high photobleaching resistance, and easy processing; thus, they have attracted a lot of attention. However, the intrinsic self-aggregation of nanoscale-sized CDs leads to fluorescence quenching, thereby limiting their application in the solid state. In this work, we demonstrate an effective and universal method to obtain solid-state CDs with high luminescence efficiency and excellent formability. Taking advantage of the charged surfaces of most CDs, we utilize two types of eco-friendly cellulose derivatives with pos. or neg. charges to surround the CDs via electrostatic attractions. As a result, the particles of CDs have been isolated and their aggregation-induced quenching phenomenon has been inhibited. The obtained CDs@cellulose derivative powders show bright fluorescence and have a high fluorescence quantum yield (QY); for example, the QY of blue-emitting powder reaches up to 71.5%. Such a simple strategy is available for various CDs. More significantly, the excellent processability and formability of cellulose derivatives enable CDs@cellulose derivatives to be easily processed into films, coatings, and printing inks, providing a huge potential in eco-friendly solid-emitting devices and light-stable anticounterfeiting labels. CDs-based solid fluorescent materials were fabricated by constructing a shell layer with charged cellulose chains via electrostatic attractions.

Qin, Yaoguo published the artcileDesign, synthesis and biological activity of novel aphid alarm pheromone analogues containing isonicotinic acid, Name: 2-Chloroisonicotinic acid, the publication is Gaodeng Xuexiao Huaxue Xuebao (2016), 37(11), 1977-1986, database is CAplus.

A series of new aphid alarm pheromone [(E)-β-farnesene, EBF] analogs containing isonicotinic acid was designed based on the principles of connecting sub-structure and bioisosterism. With EBF as a lead compound, 20 EBF analogs were prepared via four steps starting from geraniol. Their structures were confirmed by ¹H NMR, ¹³C NMR, IR and HRMS. The preliminary bioassay suggested that all the analogs showed repellent and aphicidal activities against Myzus persicae (Sulzer). Among them, compounds 7d, 8f and 8n showed good repellent activity with the repellent rate of 62.6%, 62.0% and 61.0% resp.; and the analogs 8a, 8b and 8d exhibited better aphicidal mortality of 73.6%, 81.1% and 70.2% than lead EBF. The primary structure-activity relationship (SAR) anal. indicated that introducing of ester group was favorable to repellent activity while introducing amide was conducive to aphicidal activity. Moreover, N-substituted carbon chain length, number of branched chain as well as aromaticity played roles in repellent activity. This study provides useful clues for further development of novel aphid control agent.

Wang, Xiu Li published the artcileα-γ-Type [Mo₈O₂₆]^4--Containing Metal-Organic Complex Possessing Efficient Catalytic Activity toward the Oxidation of Thioether Derivatives, Recommanded Product: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride, the publication is Inorganic Chemistry (2021), 60(5), 3331-3337, database is CAplus and MEDLINE.

In this work, a new α-γ-type [Mo₈O₂₆]^4- anion was first synthesized and characterized by single-crystal X-ray diffraction anal. and was obtained by introducing molybdate to the synthesis of metal-organic complex (MOC) under hydrothermal conditions. An octamolybdate-based MOC, namely, {[Cu₈(H₂O)₆](dpyh)₄(α-γ-Mo₈O₂₆) }·(β-Mo₈O₂₆)·8.5H₂O (1) (H₂dpyh = N,N-bis(3-pyrazolamide)-1,2-hexahydrobenzene), was obtained. The α-γ-type [Mo₈O₂₆]^4- anion was composed of four MoO₆ octahedra and four MoO₅ trigonal bipyramids by sharing their edges and corners. The title complex exhibited a 1D structure in which an α-γ-type [Mo₈O₂₆]^4- anion was connected with [Cu₄(dpyh)₂] units in a staggered manner. Under optimized conditions, complex 1 as the catalyst can achieve a highly efficient conversion (more than 99%) of thioanisole within 30 min and above 99% selectivity toward sulfoxide. Furthermore, efficient catalytic oxidation of thioether derivatives was also performed with 1 as the catalyst. In addition, the stable electrochem. sensing performance and adsorption capacity toward organic dyes were tested.
