Thermal decomposition activation energy (Ea) of star polymer was determined by the Flynn-Wall-Ozawa and Kissinger methods. The average activation energy in the range of 0.02-0.3 conversion range was determined as 115.28 kJ/mol and 152.72 kJ/mol, resp. Polymer composites were prepared by adding graphene particles in different ratios (0.5%, 1.0%, 2.0%, and 4.0% by weight) to the polymer matrix. The dielec. properties of star polymer and graphene composites were investigated in a range of 100 Hz-20 kHz frequency. Besides, the dielec. properties of the pure polymer were examined as a function of frequency at different temperatures (25°C, 40°C, 55°C, 70°C,). Furthermore, the polymer/4% graphene composite/p-Si thin-film heterojunction diode properties were investigated using current-voltage (I-V) anal. at room temperature in dark. The elec. parameters of heterojunction diode such as the rectification ratio (RR), barrier height (Φb) and ideality factor (n) were investigated. The frequency dependence of capacitance and the role of interface states were examined The results showed that chalcone substituted three-arm star polymer/4% graphene composite has a diode and capacitor characteristic.

Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Stable Radical Cation-Containing Covalent Organic Frameworks Exhibiting Remarkable Structure-Enhanced Photothermal Conversion. Author is Mi, Zhen; Yang, Peng; Wang, Rong; Unruangsri, Junjuda; Yang, Wuli; Wang, Changchun; Guo, Jia.

The production of a radical cation-containing covalent organic framework (COF) has been accomplished by sequential in situ reactions, quaternization, and one-electron reduction of the 2,2′-bipyridine-based COFs. The acid-catalyzed COF formation enables the cis configuration of 2,2′-bipyridyl moieties in the structure, of which the stability arises from the eclipsed stacking of the two-dimensional layered structure. The postfunctionalization generates cyclic alkylated diquats as the sole products from the controlled quaternization. The reduction of diquat cations on the COF skeletons results in a large number of radical cations, which delocalize and uniaxially stack on top of one another by virtue of interlayered π-electronic couplings. The absorption of the near-IR (NIR) region exhibited by the cationic radical COF is remarkably high owing to the intercharge transfer across the π-coupling interlayers. Also, the long-range array of extended and planar frameworks in such a COF leads to the extra stability of the radical cations against external stresses. The structure-enhanced performance of the COF material is witnessed with photothermal conversion efficiencies of as high as 63.8 and 55.2% when exposed to 808 and 1064 nm lasers, resp. Further PEG modification on such a COF allows photoacoustic imaging and photothermal therapy in vivo under NIR light illumination to be manifested.

Reference of 5,5′-Dimethyl-2,2′-bipyridine. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Dehydrogenative Synthesis of 2,2′-Bipyridyls through Regioselective Pyridine Dimerization.

2,2′-Bipyridyls have been utilized as indispensable ligands in metal-catalyzed reactions. The most streamlined approach for the synthesis of 2,2′-bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium-catalyzed dehydrogenative synthesis of 2,2′-bipyridyl derivatives The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2-positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3-substituted pyridines, where the pyridines regioselectively react at the C2-position. This reaction enables the concise synthesis of twisted 3,3′-disubstituted-2,2′-bipyridyls as an underdeveloped class of ligands.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Group 6 Metal Complexes as Electrocatalysts of CO2 Reduction: Strong Substituent Control of the Reduction Path of [Mo(η3-allyl)(CO)2(x,x’-dimethyl-2,2′-bipyridine)(NCS)] (x = 4-6), the main research direction is methylbipyridine allyl molybdenum carbonyl complex preparation redox potential DFT; crystal structure methylbipyridine allyl molybdenum carbonyl complex; mol structure methylbipyridine allyl molybdenum carbonyl complex; optimized geometry bipyridine allylmolybdenum complex anion radical complex DFT.Formula: C12H12N2.

[Mo(η3-allyl)(CO)2(x,x’-dmbipy)(NCS)] (dmbipy = dimethyl-2,2′-bipyridine; x = 4-6) were synthesized and their electrochem. reduction studied using combined cyclic voltammetry (CV) and variable-temperature spectroelectrochem. (IR/UV-visible SEC) in THF and butyronitrile (PrCN), at Au and Pt electrodes. The exptl. results, strongly supported by d. functional theory (DFT) calculations, indicate that the general cathodic path of these Group 6 organometallic complexes is closely related to that of the intensively studied class of Mn tricarbonyl α-diimine complexes, which, themselves, have recently been identified as important smart materials for catalytic CO2 reduction The di-Me substitution on the 2,2′-bipyridine ligand backbone has presented new insights into this emerging class of catalysts. For the 1st time, the 2e- reduced 5-coordinate anions [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- were directly observed with IR spectroelectrochem. (IR SEC). The role of steric and electronic effects in determining the reduction-induced reactivity was also studied. For the 6,6′-dmbipy, the primary 1e- reduced radical anions exert unusual stability, radically changing the follow-up cathodic path. The 5-coordinate anion [Mo(η3-allyl)(CO)2(6,6′-dmbipy)]- remains stable at low temperature in strongly coordinating butyronitrile and does not undergo dimerization at elevated temperature, in sharp contrast to reactive [Mo(η3-allyl)(CO)2(4,4′-dmbipy)]- that tends to dimerize in a reaction with the parent complex. The complex with the 5,5′-dmbipy ligand combines both types of reactivity. Under aprotic conditions, the different properties of [Mo(η3-allyl)(CO)2(x,x’-dmbipy)]- are also reflected in their reactivity toward CO2. Preliminary CV and IR SEC results reveal differences in the strength of CO2 coordination at the free axial position. Catalytic waves attributed to the generation of the 5-coordinate anions were observed using CV, but only a modest catalytic performance toward the production of formate was demonstrated by IR SEC. For 6,6′-dmbipy, a stronger catalytic effect was observed for the Au cathode, compared to Pt.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1762-34-1, is researched, Molecular C12H12N2, about Exploiting the versatility of pyridyl ligands for the preparation of diorganotin (IV) adducts: spectral, crystallographic and Hirshfeld surface analysis studies, the main research direction is diorganotin pyridyl complex preparation Hirshfeld surface analysis; crystal structure mol diorgano tin bidentate pyridyl complex supramol.Formula: C12H12N2.

Diorganotin (IV) complexes SnR2X2 (R = Me, Ph; X = Cl, NCS) form a series of versatile complexes when react with bidentate substituted pyridyl ligands. The reaction of dimethyltin dichloride with 5,5′-dimethyl-2,2′-bipyridine (5,5′-Me2bpy) resulted in the formation of [SnMe2Cl2(5,5′-Me2bpy)] (1). Moreover, the reaction of SnMe2(NSC)2 with 4,4′-di-tert-butyl-2,2′-bipyridine (bu2bpy), 1,10-phenanthroline (phen) and 4,7-diphenyl-1,10-phenanthroline (bphen) affords the hexa-coordinated complexes [SnMe2(NCS)2(bu2bpy)] (2), [SnMe2(NCS)2(phen)] (3) and [SnMe2(NCS)2(bphen)] (4), resp. The resulting complexes have been characterized using elemental anal., IR, multinuclear NMR (1H, 13C, 119Sn) and DEPT-135° NMR spectroscopy. On the other hand, the reaction of diphenyltin dichloride with 2,2′-biquinoline (biq) and 4,7-phenantroline (4,7-phen) led to the formation of polymeric complexes of [SnPh2Cl2(4,7-phen)]n (5) and [SnPh2Cl2(biq)]n (6).

The X-ray crystal structures of complexes [SnMe2Cl2(5,5′-Me2bpy)] (1), [SnMe2(NCS)2(bu2bpy)] (2) and [SnMe2(NCS)2(bphen)] (4) have been determined which reveal that the geometry around the tin atom is distorted octahedral with trans-[SnMe2] configuration. Interestingly, the crystal structure of (H2biq)2[SnPh2Cl4]•2CHCl3 (7) was characterized by X-ray crystallog. from a chloroform solution of [SnPh2Cl2(biq)]n (6) indicating the formation of doubly protonated [H2biq]+ and [Ph2SnCl4]2- which are stabilized by a network of hydrogen bonds with a feature of trans-[SnPh2]. The 3D Hirshfeld surface anal. and 2D fingerprint maps were used for quant. mapping out of the intermol. interactions for 1, 2, 4 and 7 which show the presence of π-π and hydrogen bonding interactions which are associated between donor and acceptor atoms (N, S, Cl) in the solid state.

Author is Pan, Yao; Zhang, Nan; Liu, Chun-Hua; Fan, Shilu; Guo, Song; Zhang, Zhi-Ming; Zhu, Yuan-Yuan.

The merger of photocatalysis and transition-metal catalysis is of particular interest to develop useful and challenging synthetic methodologies. The catalytic activities of conventional dual-catalytic systems, however, are limited by the low synergistic efficiency between discrete catalytic centers due to their long average distance in solution Herein we carefully decorated Ir(III) photosensitizers and Ni(II) transition-metal catalyst into flexible polymers to afford two polymer-supported dual catalysts (P1-Ni and P2-Ni). These polyelectrolyte-type metallopolymers assembled into spherical polymer particles in some polar solvents. Their unique mol. and assembled structure contributed to shortening the distance between catalytic centers and increasing the local catalysts′ concentration within the catalyst, thereby greatly facilitating their electron, energy, and organic radical transfers during the catalytic cycles. The enhanced energy interaction and matched redox potential between two catalytic centers within the polymer were confirmed by steady- and transient-state luminescent spectra and cyclic voltammetry. These features enable them in catalyzing challenging organic transformations that involve efficiently incorporated photocatalytic and transition-metal catalytic cycles. We demonstrated that these two catalysts were highly effective in catalyzing C-S cross-coupling, C-O functionalized, C-N cross-coupling, and C-C cross-coupling reactions with broad substrate scopes and low catalyst loadings with turnover numbers of ~3100, ~1500, ~1400, and ~500, resp. This work provides a general methodol. to merge photosensitizer and transition-metal catalyst in a flexible polymer for significantly boosting the catalytic activity.
