A new synthetic approach for fluorinated alkoxytriphenylene discotic liquid crystals is presented. This methodol. exploits the previously described photocyclodehydrofluorination (PCDHF) reaction for the preparation of fluorinated triphenylene derivatives coupled with a variety of nucleophilic aromatic substitution (S_NAr) reactions. This particular combination of reactions provides a versatile route to discotic materials with carefully controlled core fluorine and alkoxy tail content. In the course of these studies, new discotic materials with minimal tail content have been revealed. The mesogenic properties of these materials are reported, and their charge transport properties are measured using the time of flight technique.

The influence of complexation on the frequency of the I-Br fundamental stretching vibration in iodine bromide complexes has been investigated. The frequency and the intensity of this band are strongly influenced by the strength of the iodine bromide-electron donor interaction. The position of the IBr band varies from 261 cm.-1 in CCl4 solutions to 205 cm.-1 for the pyridine-IBr complex dissolved in benzene. In solid complexes the IBr band is split into a doublet. The changes in frequency are analyzed to obtain changes in force constants Some attempt is made to interpret these results. 31 references.

Yagi, Yoshiharu published the artcileNew polyhalide complex ions, Recommanded Product: Pyridine Iodochloride complex, the publication is Inorganic and Nuclear Chemistry Letters (1965), 1(1), 21-4, database is CAplus.

Polyhalide complexes of the type A.HICl₂.ICl (A = organic base) were prepared by dissolving a A.HICl₂ complex in 1,2-dichloroethane, adding a 4-5 fold excess of ICl, and diluting the resulting solution with CCl₄. The compounds prepared and their m.ps. are: 2,2′-bp.HICl₂.ICl (65-7°) (bp = bipyridine); 4,4′-Me₃-2,2′-bp.HICl₂.ICl (57-9°); 2,2′-bq.HICl₂.ICl (139-40°) (bq = biquinoline); 1,10-phen.HICl₂.ICl (96.5-7.5°) (phen = phenanthroline); 2,9-Me₂-1,10-phen.HICl₂.ICl (97-8°); 4,7-Me_2-1,10-phen.HICl₂.ICl (114-15°); py.HICl₂.ICl (85-6°); 2,6-lu.HICl₂.ICl (lu = lutidine); and Me₄N.ICl₂.ICl. The last 2 were red-orange oils which, on cooling, solidified to glasses; the others precipitated as orange microcrystalline powders. All are quite stable at room temperature They decomposed slowly by atm. moisture. They are soluble in many organic solvents (except CCl₄), dissociating to A.HICl₂ and ICl. They lose a mole of ICl on heating to ∼100°. Ir data seems to indicate the I₂Cl₃^– ion.

Stoffelbach, Francois published the artcileHow the interplay of different control mechanisms affects the initiator efficiency factor in controlled radical polymerization: An investigation using organometallic Mo^III-based catalysts, Product Details of C5H9IO2, the publication is Journal of Organometallic Chemistry (2007), 692(15), 3133-3143, database is CAplus.

Compound CpMoI₂(iPr₂dad) (iPr₂dad = iPrN=CH-CH=NiPr), obtained by halide exchange from CpMoCl₂(iPr₂dad) and NaI, has been isolated and characterized by EPR spectroscopy, cyclic voltammetry, and X-ray crystallog. Its action as a catalyst in atom transfer radical polymerization (ATRP) and as a spin trap in organometallic radical polymerization (OMRP) of styrene and Me acrylate (MA) monomers has been investigated and compared with that of the dichloro analog. Compound CpMoCl₂(iPr₂dad) catalyzes the ATRP of styrene and MA with low efficiency factors f (as low as 0.37 for MA and Et 2-chloropropionate as initiator), while it irreversibly traps the corresponding growing radical chains under OMRP conditions. On the other hand, compound CpMoI₂(iPr₂dad) has a greater ATRP catalytic activity than the dichloro analog and yields f = 1 for MA and Et 2-iodopropionate as initiator. Under OMRP conditions, it does not irreversibly trap the growing radical chains. This comparison serves to illustrate the general principle that low initiator efficiency factors, sometimes observed in ATRP, may result from the interplay of the ATRP and OMRP mechanisms, when the latter ones involves an irreversible radical trapping process.

The electronic structure of SbCl5.L, SnCl4.L2 (L = MeCN and ClCN), and ICl.Py complexes was calculated by using the CNDO/2 method. From the AO population, the quadrupole interaction constants, charge transfer, and charge distribution were estimated A considerable increase in the electron d. on the Cl atoms of the acceptor mols. was observed in all cases. The charge of the central atom of the acceptor was almost constant in the SbCl3.L and ICl.Py complexes but increased in SnCl4.L2. This was explained by an inaccuracy in the Sn calculation parameters. The calculated and exptl. results of the quadrupole interaction constants were in good agreement. The interaction between I and N (and Cl) atoms in the ICl.py complexes is predominantly caused by the σ orbitals.

Wang, Changsheng published the artcileMolecular Wires Comprising π-Extended Ethynyl- and Butadiynyl-2,5-Diphenyl-1,3,4-Oxadiazole Derivatives: Synthesis, Redox, Structural, and Optoelectronic Properties, Recommanded Product: 4-Iodobenzohydrazide, the publication is Journal of the American Chemical Society (2006), 128(11), 3789-3799, database is CAplus and MEDLINE.

2,5-Diphenyl-1,3,4-oxadiazole (OXD) derivatives with terminal ethynyl- I (R = Me₃C, 2-ethylhexyloxy) and butadiynyl- II[R = Me₃C (III), dodecyloxy(IV)] substituents were synthesized in high yields. 2-Methyl-3,5-hexadiyn-2-ol was not exploited previously in the synthesis of terminal butadiynes. Crystals of II are remarkably stable to long-term storage under ambient conditions. The x-ray crystal structure of III reveals that the butadiyne moieties are spatially isolated by the aromatic moieties, which explains the high stability. Two series of derived π-conjugated mols., Donor-(CC)_n-OXD (n = 1, 2) and OXD-(CC)_n-Donor-(CC)_n-OXD (n = 1) [Donor = tetrathiafulvalene (TTF), bithiophene, 9-(4,5-dimethyl-1,3-dithiol-2-ylidene)fluorene, and triphenylamine], were synthesized using Sonogashira reactions and characterized by x-ray crystallog., cyclic voltammetry, and optical absorption/emission spectroscopy. The electron-withdrawing effect of the OXD units is manifested by a pos. shift of the donor oxidation waves in these systems: the butadiynylene spacer (n = 2) further shifts the first oxidation waves by 40-80 mV compared to analogs n = 1. The absorption spectra of TTF-OXD hybrids V and VI are blue-shifted by 80 nm compared to a bithienyl-bridged derivative and are similar to the butadiynyl-OXD building-block III, demonstrating that conjugation is disrupted by a neutral TTF unit. Solutions of the TTF-OXD and 9-(4,5-dimethyl-1,3-dithiol-2-ylidene)fluorene-OXD hybrids, V–VII are only very weakly fluorescent due to quenching from the electron-donor moieties. But the triphenylamine-OXD hybrids analogs are fluorescent; the PLQY’s of the butadiynylene derivatives are lower than those of the ethynylene-bridged analogs.

Thin films of mol. aggregates of pseudoisocyanine were obtained. Delocalization length of exciton wave function was measured with an assumption that an absorption line width is defined by disorder induced mixing of the lowest states of the 1-exciton band. Predicted effect of size enhancement of the nonlinear optical properties for mol. aggregates was observed The assumption used to determine the delocalization length coincides with the observed optical nonlinearity size enhancement.

The bacteriostatic, fungistatic, trichomonastatic, amebicidal and acaricidal activity of 58 compounds which react with SH groups, was studied. Some compounds were active in vitro, but none in vivo. In vitro cysteine (I), thioglycolate, serum, and peptone inhibited the bacteriostatic activity, suggesting a mechanism of action which involves SH-containing enzymes. XRCHCO2Et (R = H or alkyl, X = I or Br) showed a strong antimicrobial activity which diminished for R = alkyl. Of several α-bromocarbonyl compounds and α-bromonitriles, the highest activity was shown by ω-bromoacetophenone (II). Most β-nitrostyrene derivatives were very active, especially those with an electrophilic substituent in para position. Very strong bacteriostatic and fungistatic activity was shown by α-bromostyrene and α,β-dibromostyrene (III). An especially marked activity was shown by tetraiodoethylene. A broad spectrum of antibacterial activity was shown by 4-nitroquinoline 1-oxide. High activity was shown by RHgX (R = Et, 4-HO2CC6H4 and X = Cl, 2-NaO2CC6H4S) and by p-RC6H4As(SCH2CO2H)2 (R = Cl or NH2).

Integrated ir intensity measurements are reported for the vibrational fundamental bands of pyridine and of the pyridine-ICl charge-transfer complex in CHCl3 and benzene solutions An attempt has been made to interpret the large intensity changes which occur on complexation in terms of the charge-transfer model proposed by Mulliken. Intensity perturbations arise in addition to those expected for the “weak” complex approximation and several interesting anomalies in the intensity data are discussed.

Yarwood, Jack published the artcileVibrational band shape and intensity studies on molecular motions and interactions in condensed phases. Part 3. Effects of complexation on the molecular dynamics of pyridine, Quality Control of 6443-90-9, the publication is Journal of the Chemical Society, Faraday Transactions 2: Molecular and Chemical Physics (1976), 72(5), 967-74, database is CAplus.

The changes in ir band width of pyridine on complexation with ICl are consistent with a mechanism involving a large increase in the total correlation time, due to removal of a large part of the correlation function GR(t), and a subsequent broadening of the band due to increased vibrational relaxation. This relaxation is partly controlled by dipole-dipole interaction and partly by transition dipole-transition dipole interaction. The vibrational relaxation mechanism operates for free pyridine and on complexation produces a pattern of band widths dependent on the intensities, normal coordinates, and symmetry properties of the normal modes.
