Time-Resolved Photoelectron Studies of Thiophene and 2,5-Dimethylthiophene

The photoinduced dynamics of thiophene and 2,5-dimethylthiophene (2,5-DMT) were investigated upon excitation at 200 and 255 nm (2,5-DMT only) using time-resolved photoelectron spectroscopy and compared with results from ab initio coupled cluster calculations. For thiophene, depopulation of the initially excited B2(pi3pi4?) state to the lower-lying A1(pi2pi4?) state occurs within 25 ¡À 20 fs, with a subsequent bifurcation into a ring-puckering channel and a ring-opening channel with lifetimes of 80 ¡À 20 and 450 ¡À 50 fs, respectively. For 2,5-DMT, the dynamics following excitation at 200 nm is described by a monoexponential decay with a time constant of 120 ¡À 20 fs, while that following excitation at 255 nm is best fit by a biexponential decay with time constants of 115 ¡À 20 fs and 15 ¡À 3 ps, respectively. The fast signal observed after excitation of 2,5-DMT is assigned to the ring-opening channel, which is favored with respect to thiophene due to a lower excited-state barrier along the ring-opening coordinate and an increased inertia toward the ring-puckering channel. Coupled cluster calculations have been undertaken to compare the relaxation dynamics of thiophene to thiazole and isothiazole. For the latter two molecules, we find a strong gradient along the ring-opening coordinate in the Franck-Condon region of the initially populated pipi? state and predict that ring-opening is the dominating relaxation channel after photoexcitation. We use the extracted information for a comparison of the thiophene dynamics with the light-induced processes observed in other five-membered heterocyclic molecules.

Palladium(II) benzisothiazolinate (bit) complexes with amino-, acetylamino-, heterocyclic and phosphine co-ligands. Crystal structure of [Pd(bit)2(kappa2-dppe)]¡¤2EtOH

Abstract A series of square-planar palladium(II) benzisothiazolinate (bit) of the general type [Pd(bit)2L2] have been prepared and characterized by analytical and spectroscopic methods. Two synthetic routes have been employed, namely reactions of [Pd(bit)2]¡¤H2O with two equivalents of ligands (L = amine, amide, phosphine) or nucleophile displacement of chloride by benzisothiazolinate starting from trans-[PdCl2L2]. Both routes afford the new complexes in good yields as easily isolated, air and moisture stable, colored solids. The precursor, [Pd(bit)2]¡¤H2O, is itself prepared in high yields upon reaction of Na[bit] with Na2[PdCl4] in methanol and the analogous platinum complex, [Pt(bit)2]¡¤H2O, is similarly prepared from K2[PtCl4]. It is not clear if these species are mono- or dimeric, and formulation as [M2(mu-bit)4(H2O)2] with the four benzisothiazolinate spanning the metal-metal vector and possibly binding through coordination of nitrogen and oxygen is suggested. Diphosphine adducts, cis-[Pd(bit)2{kappa2-Ph2P(CH2)nPPh2}] (n = 1-4) can be prepared both upon addition of the diphosphine to [Pd(bit)2]¡¤H2O and from reactions of cis-[PdCl2{kappa2-Ph2P(CH2)nPPh2}] with two equivalents of Na[bit]. A crystal structure of cis-[Pd(bit)2(kappa2-dppe)] reveals that the benzisothiazolinate ligands are bonded in a monodentate fashion through nitrogen and this binding mode is proposed for all [Pd(bit)2L2] and [Pd(bit)2L] complexes. With dppb (n = 4) a second product is seen by NMR spectroscopy being proposed to be the part-substituted complex cis-[PdCl(bit)(kappa2-dppb)], while with dppm (n = 1) two further products are seen spectroscopically, proposed as trans-[Pd(bit)2(kappa1-dppm)2] and (more tenuously) [Pd2(bit)4(dppm)2]. The former is also prepared in good yields from reaction of [Pd(kappa2-dppm)2]Cl2 with Na[bit]. These studies show that palladium benzisothiazolinate are easily accessed and show good air and moisture stability.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C7H5NO2S2, you can also check out more blogs about27148-03-4

Dyeing properties of the disperse dyes containing cyano group based on benzisothiazole for polyester fabrics under alkali condition

One step dyeing of polyethylene terephthalate (PET) fabrics combining pretreatment and dyeing under the alkali condition was developed for cleaner production. One step dyeing of PET fabrics required that the dye used has good acid and alkali stability. In this paper, dyeing properties of three azo disperse dyes containing cyano group based on benzisothiazole, 3- (4-N-ethoxyl-N-cyanoethyl -phenyldiazenyl)-5-nitro-2,1-benzisothiazole (D1), 3-(4-N-ethyl-N-cyanoethyl- phenyldiazenyl)- 5-nitro-2,1-benzisothiazole (D2), and 3-(N-benzyl-N-cyanoethyl- phenyldiazenyl)-5-nitro-2,1-benzisothiazole (D3), were investigated under alkali condition. The results showed that polyester fabrics could be well dyed with D1, D2 and D3 under the acid condition. However, D1 was decomposed while dyeing at the alkali solution. D2 and D3 had excellent color yields under the alkali condition. The acid-alkali stability and the structure change were analyzed by UV-vis spectrum and high pressure liquid chromatography (HPLC). Gaussian 09 program package was used to optimize geometry by B3LYP method and 6-31G (d) basis set. The solvation energy of D1 in water was higher than those of D2 and D3. The electron withdrawn effect of the hydroxyl affected the energy gap of HOMO and LUMO orbits. D2 and D3 showed excellent stability in the strong alkali medium. And the dyed polyester fabrics with D2 and D3 at the alkali condition also had good fastness properties.

Effect of Steel Wires on the Microwave Pyrolysis of Tire Powders

The discharge caused by metals triggered by microwave radiation is a key issue, whereas little attention was paid to the pyrolysis of waste tires by using the interaction between microwave and metals. In this work, the effect of such factors, that is, the microwave power, the steel wire (SW) mass fraction, and its spatial position in the tire powders (TPs), as well as the flow rate of the carrier gas, on the pyrolysis of the samples were experimentally examined in a laboratory-scale microwave oven. It was observed that the addition of SWs significantly accelerated the pyrolytic reaction of the TPs with regard to the conversion rate (product yields), even at rather low power, which may lead to a more complete degradation and significant reduction in the economic cost of the process. In addition, the presence of SWs has significant effects on the composition of products with different phases, especially gas yield (up to 35.3%) and also the H2 concentration in tires (up to 16.11%) were extremely high. The research on the discharge triggered by metals subjected to microwave irradiation will be instructive for promoting the industrial applications of discharges due to microwave radiation.
