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.

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.

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.

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.

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.

More, Pawan P. published the artcileAll-in-one display device with multicolor states derived from NBU-3 MOF/monoalkylated viologen hybrid ionogel material, Application of 1-Iodohexane, the publication is Dyes and Pigments (2021), 109730, database is CAplus.

Recently, metal-organic frameworks (MOFs) have gained considerable attention for electrochromic (EC) applications owing to their improved electrochem. performance and superior processing ability. As a class of well-recognized organic EC materials, viologens are desirable and they are major active EC components for most of the marketed EC devices due to their structural versatility and property tunability. Over the past two decades, extensive efforts have been made to design and synthesize different types of viologen-based materials with enhanced EC properties. Herein, we report fabrication of MOFs and 1-hexyl-[4,4′-bipyridin]-1-ium bis (trifluoromethane sulfonyl) imide [MHV][TFSI] based all-in-one hybrid ionogel as an electrochromic device (ECD). The fabricated ECD showed reversible multicolor property with stability over 2000 cycles. Initially, the ECD showed light yellow color, and subsequently, it changed to light green, blue, and maroon color accordingly. The fabricated ECD displayed fast coloration time(t_c), and bleaching times(t_b) of 4.35 s and 7.72 s, resp., along with a coloration efficiency of 99.14 cm²/C. The performance enhancement mechanisms are also concisely discussed in the present work. This work introduces the novel way to fabricate MOF based electrochromic ionogel (ECIG) ECDs and paves the way to the advancement of electrochromic ionogel-based display devices.

Puguan, John Marc C. published the artcileAchieving transmissive-to-black chromism via engineered dual electro-thermoresponsive single-molecule for full modulation of solar transmittance, Related Products of iodides-buliding-blocks, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2022), 437(Part_1), 135157, database is CAplus.

Pursuit of complete and null transmissive optical material in smart windows for full control of the intensity and spectrum of incoming solar light has led to the advancement of transmissive-to-black chromism. While most reported transmissive-to-black devices are elec. stimulated, we report here an alternative approach based on dual stimulation of a new dual responsive mol. By integrating asym. viologen onto a newly engineered poly(2-isopropyl-2-oxazoline)-based mol., one can achieve transmissive-to-black chromism. The synergistic effect of its thermochromic and electrochromic response when stimulated simultaneously shows full absorption of the entire visible solar spectrum resulting to a truly black state that is ideal for building facades requiring absolute privacy. Autonomous chromic switchability function is also possible by independently stimulating the material either elec. or thermally where it displays unique colored state of vibrant magenta and a hazy state, resp. Tunability of the material’s overall performance in terms of optical contrast, switching kinetics, coloration efficiency and cyclic stability based on the lattice water concentration was elucidated in this work. Furthermore, the fabricated device displays self-bleaching property and has a short-term “memory” effect that may broaden its potential for other applications.
