The kinetics of the photoelectrochemical mineralization of p-nitrophenol (PNP) and p-methoxyphenol (PMP) on rutile:anatase TiO2 nanotube electrodes (% rutile: 0, 16, and 20) has been studied. Oxidative photocurrent enhances with the increase of both the electrode potential and the rutile content. Time-resolved photoluminescence measurements reveal that incorporation of rutile into anatase nanotubes has effects on recombination dynamics. From measurements of electrical charge as a function of time under thin-layer conditions under potentiostatic control, it was determined that the oxidation of PNP and PMP follows the apparent Langmuir-Hinshelwood rate law. Chemical oxygen demand measurements confirmed total oxidation. The reaction rate parameters that define the kinetic constant (k) due to the reaction of hydroxyl radicals with adsorbed phenols and the thermodynamic constant (K) due to the adsorption of phenols with the electrode surface have been decoupled. The interaction of PNP with the surface of all TiO2 electrodes is highly favored, K(PNP) > K(PMP), resulting in a surface concentration of PNP considerably higher than that of PMP. The specific rate of the surface reaction for the transformation of phenols also increases, but the trend is inverse, that is, for all electrodes, k(PMP) > k(PNP). Understanding these kinetic tendencies can lead to better transformation of light in redox reactions.

A new synthetic methodology has been developed for the synthesis of sulfinate alkyl and aryl esters. The methodology involves the combination of p-toluenesulfinic acid and 1,1′-carbonyldiimidazole (CDI) to create the putative reagent sulfinylimidazole. The process spontaneously releases carbon dioxide upon the addition of the CDI to the acid suggesting the rapid formation of the proposed reagent. Reaction of this reagent with a series of alcohols (primary, secondary, and tertiary) afforded the corresponding sulfinate alkyl esters in good to excellent yields by the addition of alcohols. It was also possible to form the related sulfinate aryl esters by treating the proposed sulfinylimidazole with selected phenols (phenol, p-tert-butylphenol, and thymol). The aryl esters were formed in excellent conversion based on analysis of the 500 MHz H-1 NMR spectra of the crude reaction mixtures.

A postpolymerization nucleophilic aromatic substitution reaction is used as a strategy to efficiently diversify conjugated polymers. Conjugated polymers and small molecular models bearing tetrafluorophenyl and octafluorobiphenyl units are reacted with thiophenol derivatives, phenol derivatives, and carbazole in the presence of bases. Model reactions provide insights into the reactivity, numbers and patterns of substitution, structural features, and spectroscopic data. Thiophenol derivatives and carbazole achieve complete substitution of fluorine atoms in both the polymer and the model reactions, whereas phenol derivatives result in disubstitution in each arene ring with para-selectivity. The highly twisted and structurally rigid main chain structures are confirmed for a fully substituted arene motif in both the polymers and the models, resulting in the formation of syn- and anti-atropisomer or axial chirality and in the twisted intramolecular charge transfer character. The obtained polymers and models show unique optical and electrochemical properties, including phosphorescence at low temperatures in the case of the sulfur-containing materials.

A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I-2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields. The broad applicability of this methodology was further highlighted by the late-stage functionalization of several phenol-containing natural products and pharmaceuticals.

Mild oxetane opening by soft carbon nucleophiles has been developed for efficient C-C bond formation. In the presence of LiNTf2 or TBSNTf2 as catalyst, silyl ketene acetals were found to be effective nucleophiles to generate a wide range of highly oxygenated molecules, which are key substructure in natural products like polyketides. Furthermore, intramolecular oxetane opening by a styrene-based carbon nucleophile via a Prins-type process was also achieved with Sc(OTf)(3) as catalyst, leading to efficient formation of the useful 2,3-dihydrobenzo[b]oxepine skeleton.

Light Emitting Polymers (LEPs) have gained attention in optoelectronics. However, stability and regulation of emission color remain a challenge. This study aims to overcome the challenge by formulating a Polymer Blend (PB) which consists of a LEP ? poly [2-methoxy,5-(2-ethylhexyloxy)1,4-phynylenevinylene (MEH-PPV) and a non-conjugated polymer ? poly(methyl methacrylate) (PMMA). A simple approach of in situ polymerization of the non-conjugated polymer in the MEH-PPV solution leads to alteration of size of the MEH-PPV polymer chain and modified the emission color from red-orange to bluish-green. The barrier properties of PMMA improve the stability of PB in an ambient environment with unnoticeable luminescence loss. This type of PB shall find application in Organic Light-Emitting Devices.

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one-pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23-90 degrees C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with a wide variety of useful functional groups and were successfully applied as chiral ligands for metal catalysis. Computational studies gave a first rationalization of the low activation energy for the cycloaddition based on counter-intuitive favorable dispersive interactions in the transition state.

The effect of introducing a lateral methyl substituent and the two different alkoxy terminal groups on the mesophase behavior of three-benzene-ring molecular core of azo-ester compounds bearing 2-methylbutoxy unit on the opposite terminal side (C1-C6) were explored. Their structures were confirmed by several spectroscopic techniques (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance spectroscopy). The mesomorphic properties of these compounds were studied by differential scanning calorimetry, polarized optical microscopy, and small- and wide-angle X-ray scattering. Except for the un-substituted terminals (C1 and C4), all other derivatives are liquid crystalline, exhibiting enantiotropic nematic liquid crystal phase. The alteration of the alkoxy chain length from methoxy to butoxy at the phenyl ester terminal group (ring A) for each set of laterally-neat and laterally methyl-substituted mesogens decreases the nematic temperature range. A decrease in the mesophase temperature range is also observed when a lateral methyl substituent is incorporated into phenylazo ring of the mesogenic core (ring C). Optical study demonstrated that their absorption spectra are identical in shape due to the structural similarities of the mesogenic core. The corresponding fluorescence spectra exhibited blue-emission with the laterally methyl substituted compounds having a relatively higher fluorescence intensity compared to that of its laterally un-substituted analogues. Furthermore, the laterally methyl-substituted derivatives were subjected to the planar alignment and their dielectric and electro-optic properties were investigated. The nematic phase of the aligned samples shows antiferroelectric switching behavior with spontaneous polarization, P-s similar to 5 mu C/cm(2). (C) 2021 Elsevier B.V. All rights reserved.
