This study describes the enhancement in the solubility and controlled-release of fragrance agents (menthol, four n-alkanols, and three aromatic esters) using three CO₂ switchable surfactants (N-alkylimidazolium bicarbonates). The surfactants significantly improved the solubility of fragrance agents in water. N-Dodecylimidazolium bicarbonate was the most effective surfactant to solubilize menthol. A stability test indicated that the surfactant could stably disperse menthol in water. Moreover, the surfactants improved the solubility of n-alkanols to different levels, however, the solubility of the aromatic esters equally. The release of menthol from the surfactant solution under N₂ at different durations of bubbling time, temperatures, and flow velocities were studied.

Sokolsky, Alexander published the artcileSynthesis of a C(1)-C(23) Fragment for Spirastrellolide E: Development of a Mechanistic Rationale for Spiroketalization, Safety of (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Organic Letters (2015), 17(8), 1898-1901, database is CAplus and MEDLINE.

Synthetic anal. of spirastrellolide E envisioned to entail a cross-metathesis union of the northern and southern hemispheres followed by a Sharpless epoxidation/methylation sequence to achieve the C(22,23) stereogenicity leads to the design of a C(1)-C(23) advanced southern hemisphere, I, exploiting a gold-catalyzed directed spiroketalization as a key step. Stereochem. anal. of this strategic transformation provides insight on the impact of the directing group carbinol stereogenicity on the reaction efficiency and, in turn, permits the conversion of the minor isomer of the spiroketal precursor to the requisite congener for successful spiroketalization.

Ebert, Max published the artcileJoint Venture of Metal Cluster and Amphiphilic Cationic Minidendron Resulting in Near Infrared Emissive Lamellar Ionic Liquid Crystals, SDS of cas: 143-15-7, the publication is Chemistry – A European Journal (2022), 28(3), e202103446, database is CAplus and MEDLINE.

Red-near-IR emissive hybrid materials obtained with phosphorescent octahedral Mo cluster anions electrostatically associated with amphiphilic guanidinium minidendrons are presented. Polarized optical microscopy and x-ray anal. show that while the minidendron chloride salts self-organize into columnar phases, their association with the dianionic metal cluster leads to layered phases. Steady-state and time-resolved emission studies demonstrate the influence of the minidendron alkyl chain length on the phosphorescence of the metal cluster core.

Rossi, Renzo published the artcileSelective and efficient syntheses of phototoxic 2,2′:5′,2”-terthiophene derivatives bearing a functional substituent in the 3′- or the 5-position, HPLC of Formula: 69361-41-7, the publication is Tetrahedron (1991), 47(39), 8443-60, database is CAplus.

Efficient and selective procedures were developed to prepare on a medium scale several phototoxic 2,2′:5′:2″-terthiophene derivatives of general formula 2 (X = OEt, SMe) and 3 [Y = CHF₂, OMe, Br, CO₂Et, CONHCH₂CHMe₂, CH:CHCO₂Et-(E), CH:CHCONHCH₂CHMe₂-(E), CC-CH₂CH₂CH:CHCONHCH₂CHMe₂-(E)] which are characterized by a functional substituent in the 3′- or the 5-position. Most of these procedures, which are based on the construction of the 2,2′:5′,2”-terthiophene moiety and involve palladium-mediated carbon-carbon bond forming reactions, overcome synthetic difficulties found in the synthesis of 2 and 3 starting from 2,2′:5′,2”-terthiophene 1 (R¹-R⁶ = H).

Intramol. (3+2) cycloaddition reaction between alkynyl sulfides (neutral TAC) and alkynes to provided key thiophenium ylide intermediates was first reported. These reactive species provided access to highly substituted fused thiophenes following predictable chem. sequences. Structural features on the obtained thiophenes were highly configurable by judicious choice of both alkynyl sulfide substitution and reaction conditions.

Boga, Carla published the artcileElectron reduction processes of nitrothiophenes. A systematic approach by DFT computations, cyclic voltammetry and E-ESR spectroscopy, Related Products of bromides-buliding-blocks, the publication is Organic & Biomolecular Chemistry (2012), 10(39), 7986-7995, database is CAplus and MEDLINE.

In the framework of the interest in nitrothiophenes as drugs or hits with different pharmacol. applications and considering that in several instances nitroredn. is an essential step for their biol. activity, the authors have studied a complete series of mono-, di-, and tri-nitrothiophenes and by comparison some mononitro benzo[b]thiophenes and benzo[b]furans . Their electroreduction behavior was studied by different techniques: DFT calculations, cyclic voltammetry and electrochem. ESR spectroscopy. Although, the first reduction process for all of the compounds leads to the relevant radical anions, both the computational and there are significant differences in the fate of their corresponding forthcoming reductions, for example, formation of secondary radicals (open-shell electronic structures) or dianions. The effect of the relative positions of the nitro groups during the reduction also was analyzed and rationalized.

Goti, Giulio published the artcileDonor-Acceptor-Donor Thienopyrazine-Based Dyes as NIR-Emitting AIEgens, Category: bromides-buliding-blocks, the publication is European Journal of Organic Chemistry (2021), 2021(18), 2655-2664, database is CAplus.

Organic Near-IR luminophores have found broad application as functional materials, but the development of efficient NIR emitters is still a challenging goal. Here we report on a new class of thieno[3,4-b]pyrazine-based NIR emitting materials with Aggregation Induced Emission (AIE) properties. The dyes feature a donor-acceptor-donor (D-A-D) structure, with a thienopyrazine acceptor core connected to two triarylamine donor groups bearing a tetraphenylethylene (TPE) moiety. Fast and efficient synthesis allowed the modular preparation of three dyes of tunable absorption and emission profiles. These constructs were extensively characterized by spectroscopic studies in different solvents, which revealed intense light-harvesting ability and emissions in the deep-red and NIR region with large Stokes shift values. Remarkably, the dyes exhibited AIE properties, retaining emissive ability in the aggregate state, thus emerging as attractive materials for their potential application in the development of luminescent devices.
