Selective [2 + 2]-cycloaddition in methacrylic stilbene polymers without interference from e / Z -Isomerization

Stilbene is known to undergo two different reactions upon photochemical excitation. The first is an E/Z isomerization and the second is a [2 + 2]-cycloaddition of two stilbene molecules. Because both reactions occur in parallel their use is limited. Here we report on photorefractive polymers with a methacrylate backbone and covalently attached 4-hydroxy-(E)-stilbene or 3,5-dimethoxy-4-hydroxy-(E)-stilbene units in the side chain which show [2 + 2]-cycloaddition only. Both polymers, poly(4-methacryloyloxy-(E)-stilbene) (PMAES) and poly(4-methacryloyloxy-3,5-dimethoxy-(E)-stilbene) (PMADMES), show very high initial refractive indices of 1.6533 for PMAES and 1.6288 for PMADMES. The photochemical reaction upon laser irradiation with 355 nm was monitored by UV/vis, fluorescence, and IR spectroscopy. The light-induced changes of the refractive index at 633 nm measured by surface plasmon resonance (SPR) were found to be Deltan > 0.05 for PMAES and Deltan > 0.04 for PMADMES. The sensitivity of PMADMES is enhanced compared to PMAES due to the electron donating groups (EDG) as the direct comparison of both polymers shows. Both polymers are useful for optical devices because they do not show any absorption in the visible range and are noncrystalline as determined by wide-angle X-ray scattering (WAXS) and differential scanning calorimetry (DSC).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C10H24N2, you can also check out more blogs about4062-60-6

High efficient Light-Emitting Electrochemical Cells based on ionic liquids 1,2,3-triazolium

The Light-Emitting Electrochemical Cell (LEEC) is one of the simplest kind of electroluminescent solid-state devices. Generally, they are fabricated with only one emitting material layer (EML), so-called active emission layer, that consist of an emitter material mixed with an ionic electrolyte. Apart from the electrolyte, their structure is similar to that of a single layer organic light-emitting diode (OLED). Not only LEECs assemble most of OLEDs applications and their technological advantages, but they also bring additional ones such as (i) low dependence of the electrodes work function, (ii) low dependence to the EML thickness, (iii) low operation voltage and high brightness and finally (iv) LEECs can be printed or sprayed in large areas. To investigate the performance of ionic liquid (IL) based devices we synthesized four organic salts that were compared with devices using four inorganic salts commonly used as electrolyte for LEECs. All devices were fabricated with a commercial poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) as emitter polymer. As a result, we showed that the best device performance was achieved with the Ionic Liquid 1-dodecyl-4-(hydroxymethyl)-3-methyl-1H-1,2,3-triazol-3-ium iodide (dohmtI) presenting a current efficiency of 3.6 cd/A, an external quantum efficiency (EQE) of 1.4% as well as a luminance of 3.2 × 104 cd/m2. Despite the use of MEH-PPV, a polymer not so efficient when compared to the state-of-art of the novel polymers employed nowadays, our realization showed these new ILs have been able to provide the specific requirements of the LEEC devices.

Photocontrollable release and enhancement of photodynamic therapy based on host-guest supramolecular amphiphiles

A light-controlled porphyrinic photosensitizer release system was developed based on host-guest TPP-Azo/PEG-beta-CD supramolecular amphiphiles, which could significantly enhance the efficiency of photodynamic therapy. TPP-Azo was prepared via esterification between TPP and Azo derivatives, and further used to construct supramolecular amphiphiles with PEG-beta-CD. TEM images showed that TPP-Azo/PEG-beta-CD amphiphiles can self-assemble into spherical micelles, and then disaggregate under irradiation with 365 nm UV light. The phototoxicity and bio-distribution of TPP-Azo/PEG-beta-CD micelles against the MCF-7 cell line were also evaluated by MTT assay, flow cytometry and confocal scanning laser microscopy, respectively. According to MTT assay, the IC50 of the spherical micelle was 31.2 mug mL-1, but it became 20.6 mug mL-1 upon pre-irradiation with 365 nm UV light. This shows for the first time that UV light can well stimulate the release of porphyrin photosensitizers and improve the photodynamic therapy efficiency based on the system of host-guest supramolecular amphiphiles.

Fluorine-free and fluorine containing MOCVD precursors for electronic oxides: A comparison

MOCVD processes adopting two different precursors Sr(tmhd) 2pmdeta and Sr(hfac)2tetraglyme have been compared. In situ FT-IR monitoring shows that Sr(hfac)2tetraglyme posses suitable thermal stability upon sublimation and good mass-transport properties. By contrast, Sr(tmhd)2pmdeta posses lower stability which precludes efficient sublimation/evaporation processes, thus requiring reactors equipped with liquid delivery systems for efficient MOCVD processes. Insights on the MOCVD process have been obtained combining in situ FT-IR and ex situ XRD, XPS, SEM and EDX techniques. Homogeneous films have been deposited on Pt/TiN/SiO 2/Si substrates in the 300-500C temperature range. XRD and XPS analyses have shown that fluorine or carbonate containing films are obtained adopting Sr(hfac)2tetraglyme or Sr(dpm)2pmdeta, respectively.

A Tunable Route to Prepare alpha,beta-Unsaturated Esters and alpha,beta-Unsaturated-gamma-Keto Esters through Copper-Catalyzed Coupling of Alkenyl Boronic Acids with Phosphorus Ylides

A tunable strategy to prepare alpha,beta-unsaturated esters and alpha,beta-unsaturated-gamma-keto esters in good to excellent yields was developed through copper-catalyzed oxidative coupling of phosphorus ylides with alkenyl boronic acids under mild conditions. The reaction without water afforded alpha,beta-unsaturated esters, ketones, and amides while alpha,beta-unsaturated-gamma-keto esters, 1,4-alpha,beta-unsaturated diketones and alpha,beta-unsaturated-gamma-keto amides were obtained when using 5.0 equiv. of water. H2O18 labeling experiments showed that water played an important role in the formation of alpha,beta-unsaturated-gamma-keto esters. A plausible formation mechanism for alpha,beta-unsaturated esters and alpha,beta-unsaturated-gamma-keto esters was proposed based on mechanistic studies. Phosphonium salts could also be used directly as coupling partners instead of phosphorus ylides. The reaction exhibited a broad substrate scope, good functional group tolerance, good regioselectivity, and diverse coupling products. (Figure presented.).

Mesomorphic [2]rotaxanes: Sheltering ionic cores with interlocking components

Two types of liquid crystalline [2]rotaxanes based on a conventional tetracatenar motif (a rod-shaped molecule with two side chains at each end) have been prepared. Dicationic compounds with ester stoppers and tetracationic materials with pyridinium stoppers are compared to each other and their dumbbell shaped analogs. Since the ionic core contributes about 70% to the overall length and molecular weight of the molecules, sheltering the ionic cores with an interlocked neutral macrocycle has considerable effect on the mesomorphism and thermal stability of the materials. The influence of the sheltering macrocycle, the numbers of charges on the core and the size and nature of the side chains (aliphatic vs siloxane) were probed. [2]Rotaxanes with linear side chains and minimum ratios of chain-to-core volumes of about 0.35 and 0.30 for tetra- and dicationic compounds, respectively, display smectic liquid crystal phases. Larger ratios increase the temperature range of the smectic A phases beyond the decomposition temperatures; a disadvantage for processing because no stable isotropic liquid phase is available. The change from tetra- to dicationic [2]rotaxanes increased not only the fluidity of their smectic A phases but also their thermal and chemical stability. Branched side chains (2-hexyldecyl) disfavor the formation of lamellar mesophases and, instead, induce higher ordered soft crystal phases. No liquid crystal phases but soft crystal phases are observed for the analogous di- and tetracationic compounds without an ion sheltering interlocked macrocycle (dumbbells).
