In research activities toward new electrolyte materials for energy devices, the new tetracyanidoborates [Li(C8H16O4) 2][B(CN)4] (1), [Na(C8H16O 4)2][B(CN)4] (2), [Li(C10H 20O5)][B(CN)4] (3), and [Na(C 10H20O5)][B(CN)4] (4), which contain lithium and sodium metal cations coordinated by macrocyclic polyether molecules, were synthesized and characterized. Their structures were determined by single-crystal X-ray diffraction measurements. Compounds 1 and 2 form orthorhombic crystals built up from isolated ion pairs. The alkaline metal cation is coordinated by eight oxygen atoms of two 12-crown-4 (12Cr4) crown ether molecules. Compounds 3 and 4 crystallize in the monoclinic crystal system and are constructed from salt chains that extend in one direction. The Na compound has double rows of approximately face-to-face oriented complex cations, which are bridged by two CN groups of each tetracyanidoborate anion. The Li compound contains single strands. In both cases, each anion has two coordinated and two uncoordinated CN groups. The different bonding situations in all four compounds are characterized by IR, Raman, and NMR spectroscopy. Electrochemical spectroscopy was performed to obtain the overall specific conductivity of 1 and 3. Furthermore, differential scanning calorimetry (DSC) measurements revealed melting points below 200 C and decomposition temperatures above 230 C. Four new tetracyanidoborate salts, two of which have unusual chain structures, were synthesized and characterized. Thermal measurements proved them to be fairly stable compounds, and impedance measurements show that they have good conductivity.

Application of 33100-27-5, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5

A series of iminophenoxide ligand precursors [2-(RN=CH)C6H4OH] (HL1: R = C6H5; HL2: R = 2,6-iPr2C6H3) and [2-(RN=CH)-4,6-tBu2C6H2OH] (HL3: R = C6H5; HL4: R = 2,6-iPr2C6H3) were synthesized. These compounds reacted with NaN(SiMe3)2/15-crown-5 or KN(SiMe3)2/18-crown-6 to afford corresponding crown ether complexes of sodium and potassium iminophenoxides (1, (15-C-5)NaL2; 2, (15-C-5)NaL3; 3, (15-C-5)NaL4; 4, (18-C-6)KL1; 5, (18-C-6)KL2; 6, (18-C-6)KL3; 7, (18-C-6)KL4). Catalysis of the complexes toward the ring-opening polymerization of rac-lactide was studied. Each of the complexes exhibited high catalytic activity at room temperature. Complexes 2, 3, 6 and 7 showed poor isotactic selectivity and relatively broad molecular weight distributions. Complexes 1 and 5 resulted in more stereoregular polymers with Pm values of 0.58 and 0.66, respectively. Complex 4 led to the best selectivity for isotacticity (Pm = 0.75) when the polymerization was performed in toluene at 0 C.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 33100-27-5 is helpful to your research., Application of 33100-27-5

The cationic titanium fluoride containing complexes [fac-TiF 3(MeCN)3][SbF6]·MeCN (1), [trans-TiF 2(15-Crown-5)][SbF6]2 (2) and [trans-TiF 2(18-Crown-6)][SbF6]2 (3), were prepared by the reaction of TiF4, the molecular ligand and SbF5 in MeCN. Complexes 1-3 were characterized by X-ray single crystal analysis, elemental analysis, IR, NMR and mass spectroscopy. Titanium tetrafluoride reacts with the SbF5 in SO2 with the formation of fac-[TiF3(SO2)3]+, detected by 19F NMR. Application of the volume-based approach to thermodynamics (VBT) offers a means, for the first time, of exploring the energetics surrounding these materials and in the thermodynamic section a discussion of this new approach is provided. It emerges that the basis of the thermodynamic driving force of formation of [TiF3L3][SbF6](s) salts, that enforces the unfavourable [DeltaH = + 237 (±20) kJ mol-1] fluoride ion transfer from the Lewis acid TiF4(s) to SbF5(l) to give the hypothetical [TiF3] +[SbF6]- (s), is the higher Ti-L (L = ligand) bond energy in the cationic complexes [TiF3L3] + as compared to that in the molecular adducts TiF4L 2(s) and SbF5L(s) so giving rise to larger enthalpies of complexation of [TiF3]+(g) by 3L(g) compared to those for complexation of TiF4(g) by 2L(g) and SbF5(g) by 1L(g). Formation of the trans-[TiF2(15-Crown-5)]2+ and trans-[TiF2(18-Crown-6)]2+ is accounted for the stabilization of [TiF2]2+ cation by the five donor acceptor Ti-O contacts and the accompanying positive charge delocalization. Cationic titanium(IV) complexes fac-[TiF3(MeCN)3-nL n]+ (n = 0-3) and cis-[TiF3(18-Crown-6)] +, trans-[TiF2(Crown)]2+ (Crown = 15-Crown-5 and 18-Crown-6) were obtained in MeCN solution by the reaction of fac-[TiF 3(MeCN)3]+ and L = Et2O, THF, H 2O or crown ethers. Complexes fac-[TiF3(MeCN) 3-nLn][SbF6] L = Et2O, THF, H 2O, crown ethers are unstable in MeCN solution and slowly decompose giving molecular complexes cis-TiF4L2, cis-TiF 4 (Crown), SbF5L, titanium oxofluoride and alkoxide complexes. The structure of the fac-[TiF3(MeCN)3] + is similar to the fac-[TiCl3(MeCN)3] + and the complexes trans-[TiF2L]2+ L = 15-Crown-5, 18-Crown-6 have very similar geometries to that of trans-[TiCl 2(15-Crown-5)]+ showing that the essential features of coordination are the same for the cationic titanium chloride and fluoride complexes with MeCN and 15-Crown-5, 18-Crown-6.

Molecular modelling is a growing science which allows to calculate short range forces between zeolite frameworks and organic compounds. By using a steric approach, it is possible to design templates matching closely with an inorganic framework. Herein, the design, synthesis and successful application of several di(azacrown ether) templates to direct the formation of FAU- and EMT-type zeolites are reported. Following a high throughput experiment design, the synthesis gel composition was optimized to obtain well-crystallized materials. Taking into account their respective crystallization rates, their textural and morphological properties were comparable to their counterparts, typically structured by 15-crown-5 and 18-crown-6 ethers. This work is the first step toward a further design of structure- and shape-directing templates, in order to control the properties of FAU- and EMT-type zeolites aiming specific catalytic and separation applications.

The infra-red (IR) spectroscopic data for a series of 13 heteroleptic bis(phthalocyaninato) rare earth complexes M(Pc)[Pc(OC8H 17)8] [M = Y, Pr, …, Lu except Pm; H2Pc = phthalocyanine; H2Pc(OC8H17)8 = 2,3,9,10,16,17,24,25-octakis(octyloxy)phthalocyanine] have been collected with resolution of 2 cm-1. The IR spectra for M(Pc)[Pc(OC 8H17)8] are more complicated than those of homoleptic bis(phthalocyaninato) rare earth counterparts M(Pc)2 and M[Pc(OC8H17)8]2 due to the decreased molecular symmetry of these double-decker compounds, C4v. For this series of heteroleptic bis(phthalocyaninato) rare earth compounds, the Pc – marker band at 1315-1322 cm-1, attributed to the pyrrole stretching, is found to be dependent on the central rare earth size, shifting slightly to the higher energy along with the decrease of rare earth radius. The coupling of isoindole deformation and aza stretching at 1057-1063 cm -1 and the coupling of pyrrole and aza stretching at 1497-1504 cm-1 are also metal-sensitive. The frequency of the vibration at 880-884 cm-1 is also dependent on the rare earth ionic size. The assignments of the vibration bands for these compounds have been made by comparison with the IR spectra of unsubstituted and in particular the 2,3,9,10,16,17,23,24-octakis(octyloxy)-substituted bis(phthalocyaninato) rare earth analogues M(Pc)2 and M[Pc(OC8H17) 8]2.

Color modulation was first observed for CT-induced chemiluminescent decomposition of a dioxetane bearing a 3-(anthracen-9-yl)-5-hydroxyphenyl induced by a complex of crown ether with potassium tert-butoxide in benzene system. Color modulation was first observed for CT-induced chemiluminescent decomposition of a dioxetane bearing a 3-(anthracen-9-yl)-5-hydroxyphenyl induced by a complex of crown ether with potassium tert-butoxide in benzene system. The phenomenon is rationalized by conformational change of a biaryl moiety in the emitter, which is induced by steric interaction of anthryl and a plane of crown ether complex.
