Acid-free approach has been demonstrated for Friedel-Crafts-type reaction of (het)arenes with carbonyls using neutral ionic liquid (NIL). Methodol. is enabled to afford a densely functionalized bis(indolyl)methanes in good to excellent yields. This conditions is also compatible to the synthesis of 3,3-di(indol-3-yl)indolin-2-ones, bis(4-hydroxycoumarines) and triarylmethanes (total 40 examples; up to 98% yields). Gram-scale reactions and recycling study were carried out to demonstrate the practicality of present methodol. DFT studies illustrate the catalytic cycle involving simultaneous activation of C=O and indole C-H bond by NIL followed by C-C bond formation.

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.

An efficient, aerobic, chemoselective and simplified approach for the oxidation of a broad range of benzyl and propargyl alcs. containing diverse functional groups to their corresponding aldehydes and ketones in excellent yields under mild reaction conditions was reported. Optimal yields were obtained at room temperature using 1 mmol substrate, 10 mol% copper(I) iodide, 10 mol% 4-dimethylaminopyridine (DMAP) and 1 mol% 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) in acetonitrile under an oxygen balloon. The catalytic system can be applied even when sensitive and oxidizable groups such as alkynes, amines and phenols are present and also starting materials and products containing such groups were found to be stable under the developed conditions.

Far infrared intensities and NMR spectra of pyridine bases with iodine monochloride, Recommanded Product: Pyridine Iodochloride complex, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (1970), 26(11), 2099-12, database is CAplus.

Low-frequency IR and NMR spectra for complexes of ICl with a series of substituted pyridines have been obtained in an attempt to study the factors which lead to a variation in donor ability when Me group substitution is made at different positions in the ring. The presence of even one α-Me group causes a significant decrease in the ν(N-I) (intermol.) band frequency and intensity (and in the kDI force constant) relative to those found in the absence of α-Me groups. On the other hand the ν(I-Cl) band intensity varies very little on going from one base to another while the NMR spectra show that electronic rearrangement within the base mols. can be correlated, at least to some extent, with their pKa values.

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.

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.

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).
