Author is Wu, Wen-Jie; Huang, Hong-Xiang; Chen, Meng; Qian, Dong-Jin.

A silylated-terpyridine (SiTPy) derivative was newly synthesized and reacted with various transition metal ions in the solutions and self-assembled monolayers (SAMs). Composition and morphol. of the SAMs were characterized by using absorption spectra, x-ray photoelectron spectra and at. force microscope. The silylated-TPy compound gave off a luminescent emission at ∼456 nm, which slightly shifted to 452 nm in the Zn2+-SiTPy and Fe2+-SiTPy metalated complexes. The absorbed energy can be further transferred to lanthanide ions (Tb3+ and Eu3+) to give off the typical emissions of the lanthanide complexes together with an emission of the silylated-TPy at ∼363 nm.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 63295-48-7, is researched, SMILESS is O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.O=S(C(F)(F)F)([O-])=O.[Fe+3], Molecular C3F9FeO9S3Preprint, arXiv.org, e-Print Archive, Physics called Mildly-doped polythiophene with triflates for molecular recognition, Author is Boujnah, Aicha; Boubaker, Aimen; Kalboussi, Adel; Lmimouni, Kamal; Pecqueur, Sebastien, the main research direction is polythiophene iron bismuth triflate mol recognition dipole moment electrophilicity.Reference of Iron(III) trifluoromethanesulfonate.

Organic semiconductors have enough mol. versatility to feature chemo-specific elec. sensitivity to large families of chem. substituents via different intermol. bonding modes. This study demonstrates that one single conducting polymer can be tuned to either discriminate water-, ethanol- or acetone-vapors, on demand, by changing the nature of its dopant. Seven triflate salts differ from mild to strong p-dopant on poly(3-hexylthiophene) sensing micro-arrays. Each material shows a pattern of conductance modulation for the polymer which is reversible, reproducible, and distinctive of other gas exposures. Based on principal component anal., an array doped with only two different triflates can be trained to reliably discriminate gases, which re-motivates using conducting polymers as a class of materials for integrated electronic noses. More importantly, this method points out the existence of tripartite donor-acceptor charge-transfer complexes responsible for chemospecific mol. sensing. By showing that mol. acceptors can have duality to p-dope semiconductors and to coordinate donor gases, such behavior can be used to understand the role of frontier orbital overlapping in organic semiconductors, the formation of charge-transfer complexes via Lewis acid-base adducts in mol. semiconductors.

Let’s take a look at the latest research on this compound (cas:63295-48-7).

A simple method has been developed for functionalizing glycine derivatives by iron-catalyzed cross-dehydrogenative coupling (CDC) reactions. In particular, N-arylglycine derivatives reacted with alkynes by oxidative C-H/C-H coupling reactions to provide a series of substituted quinolines starting from com. inexpensive materials. Moreover, N-arylglycine esters can be oxidatively coupled to ketones by using FeCl3 in the presence of DDQ.

Synthetic Route of C3F9FeO9S3. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Highly stretchable and strong poly(butylene maleate) elastomers via metal-ligand interactions. Author is Chen, Tong; Geng, Kui; Gao, Ying; Xie, Zhi-Ning; Guo, Zhao-Xia; Xu, Jun; Guo, Bao-Hua.

The search for advanced elastomers with simultaneously high strength, high stretchability and reprocessability remains a challenging task. Herein, we report an innovative method to prepare high-performance yet reprocessable poly(butylene maleate) (PBM) elastomers by forming dynamic metal-ligand (M-L) crosslinks among PBM chains. 2-Pyrazine ethanethiol, a com. available food flavor, was used to introduce pyrazine ligands on PBM chains by the thiol-ene click reaction. A series of metal salts with different metal ion valences, counteranions and metal types were used to form metal-pyrazine interactions, showing that all three factors affect the M-L bond strength and thus the mech. behavior of the crosslinked PBM elastomers. A tensile strength as high as 4 MPa and elongation at break up to 1630% were achieved for the Fe(BF4)2-crosslinked PBM elastomer, which were 1 and 22 times better than those of a covalently crosslinked PBM elastomer, and the dynamically crosslinked PBM elastomer can be reprocessed at 100°C by hot pressing. This excellent recyclability was attributed to the dynamic nature of M-L bonds. During tensile testing, some of the M-L bonds were reversibly broken and reformed to release two types of coiled segments and enable the chain sliding, resulting in high extensibility; in the meantime, the M-L interactions and the network structure were optimized when the mol. chains were gradually oriented along the pulling direction, ensuring high strength. The designed M-L crosslinked PBMs are promising candidates for advanced elastomers with highly tunable mech. properties.

COA of Formula: C3F9FeO9S3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Asymmetric tetranuclear nickel chains with unidirectionally ordered 2-(α-(5-phenyl)pyridylamino)-1,8-naphthyridine ligands. Author is Tsou, Lien-Hung; Sigrist, Marc; Chiang, Ming-Hsi; Horng, Er-Chien; Chen, Chun-hsien; Huang, Shou-Ling; Lee, Gene-Hsiang; Peng, Shie-Ming.

The new ligand, 2-(α-(5-phenyl)pyridylamino)-1,8-naphthyridine (Hphpyany), was synthesized by a Pd(0)-catalyzed reaction of 2-chloro-1,8-naphthyridine with 2-amino-5-phenylpyridine in the presence of potassium tert-butoxide. Linear tetranickel metal complexes, [Ni4(phpyany)4Cl2](CF3SO3) 1, [Ni4(phpyany)4Cl2](BF4)2 2, [Ni4(phpyany)4(NCS)2](ClO4) 3 and [Ni4(phpyany)4(NCS)2](CF3SO3)2 4 were prepared and crystallog. characterized. Complexes 1-4 demonstrate that, for the first time, four asym. ligands align unidirectionally and thus configure (4,0)-form tetranickel strings, specifically, with the Ph groups of the four phpyany- pointing to one side of the Ni4 chain and naphthyridyl to the other. The remarkably short Ni-Ni distances (∼2.33 Å) for 1 and 3 indicate partial metal-metal bonding, which can be viewed as both complexes containing one mixed-valence Ni23+ unit. The measurements of the magnetic susceptibility reveal that Ni47+ complexes 1 and 3 exhibit antiferromagnetic interactions (J = -42 cm-1 for 1 and -46 cm-1 for 3) between the terminal Ni2+ ion and the Ni23+ unit, while Ni48+ complexes 2 and 4 exhibit antiferromagnetic interactions (J = -33 cm-1 for 2 and -35 cm-1 for 4) between the two terminal Ni2+ ions. The results of the cyclic voltammetry indicate two reversible redox couples at E1/2(1) = 0.12 V, E1/2(2) = -0.65 V for 1, and at E1/2(1) = 0.12 V, E1/2(2) = -0.72 V for 3. The products of the first oxidation for 1 and 3 are the oxidized dication species 2 and 4, resp. The values of single-mol. resistance (15.4 (±3.46) MΩ for 3 and 16.2 (±5.04) MΩ for 4) were determined by STM-based break-junction methods. The results represent the first conductance measurements of linear tetranickel chains.

Compound: Iron(III) trifluoromethanesulfonate, is researched, Molecular C3F9FeO9S3, CAS is 63295-48-7, about Clean production of ethyl levulinate from kitchen waste. Author is Tian, Lu; Zhang, Luxin; Liu, Yuting; He, Yunfei; Zhu, Yujie; Sun, Ruijun; Yi, Simin; Xiang, Junping.

A clean and highly efficient catalytic system for the synthesis of Et levulinate (EL) from kitchen waste was developed. A heterogeneous catalyst (Sn/ZrP-SO3H) was prepared and the Bronsted and Lewis acid sites on the surface of the catalyst were evaluated by pyridine FT-IR. Other physicochem. properties were also characterized using XRD, SEM, FT-IR, XPS, BET, NH3-TPD. The yield of EL obtained was 49.27%, when glucose was used as the starting material and subjected to 170°C for 10 h in the presence of the solid acid catalyst, Sn/ZrP-SO3H. The prepared catalyst was also combined with several metal triflates; (Al(OTf)3, Fe(OTf)3, Sm(OTf)3) to form a catalytic system for the efficient preparation of EL from kitchen waste. Sn/ZrP-SO3H/Al(OTf)3 had superior activity compare to other catalyst combinations. In single factor experiments, the yield of EL reached 52.52% after heating at 170°C for 4 h. In addition, four-factor and three-level experiments were performed using response surface methodol. (RSM) to analyze the interaction between each factor. The optimal reaction conditions predicted by the model (163°C, 7.63 h, 20 mg Al(OTf)3, 40 mg Sn/ZrP-SO3H and 79.98 mg of kitchen waste) estimated a maximal yield for EL of 51.24%. The exptl. yield of EL however was 52.03% which confirms the reliability of the model. This work provides a cleaner production technol. for the synthesis of the high value-added chem. EL, and a sustainable route for the utilization of kitchen waste.
