Electron-accepting carborane viologen and iron based-supramolecular polymers for electrochromism and enhanced photocatalytic hydrogen evolution

Highly electron-accepting viologen derivatives, o-carborane viologens (CbV2+), and their iron based-supramolecular polymers (FeSPs) with tunable optoelectronic properties have been reported. Carborane viologens show excellent electron redox properties wit

A Configurationally Tunable Perylene Bisimide Derivative-based Fluorescent Film Sensor for the Reliable Detection of Volatile Basic Nitrogen towards Fish Freshness Evaluation

Rapid and real-time monitoring of food quality plays critical roles in the food industry and for the general public health. Herein, we specially synthesized a new perylene bisimide (PBI) derivative (PCB-EpE) composed of two PBI units and a rigid o-carborane linker, which was further employed in constructing a conceptual fluorescent film sensor for evaluating fish freshness. Photophysical studies indicate that PCB-EpE displays an open “Z-type” molecular configuration in chloroform and a closed “Δ-type” configuration in methyl cyclohexane. Comparatively, “Z-type” molecular configuration possesses higher fluorescence quantum yield and is more sensitive toward volatile basic nitrogen (VBN). It is noteworthy that the film sensor responds in less than 1 s even in ambient humidity condition. High correlation between the content of total volatile basic nitrogen (TVB-N) in evaluating fish freshness with different storage time and the fluorescence response is achieved. Detection limit of the film sensor toward trimethylamine as an example is lower than 2.6 mg/m3. Comprehensive sensing investigations demonstrate the rapid detection, strong anti-interference capability and excellent reusability of the film sensor toward testing VBN. To our knowledge, this is the first report to accurately predict TVB-N value for the evaluation of fish freshness using a fluorescent film sensor, showing great potential for real-life applications.

Structure-fluorescence relationships in pyrrole appended o-carborane crystalline materials

Based on three rationally designed pyrrole-appended o-carborane derivatives, we present that fluorescence properties of crystalline materials are highly dependent on intermolecular interaction and steric hinderance. Though the three molecules are similar

Viologen is used as a central core structure, 1,2-bis(4-pyridyl)acetylene is synthesized through a Sonagashira coupling reaction, and then alkynyl is attacked by decaborane to synthesize a carborane viologen precursor A; or alkynyl in bis(4-bromophenyl)acetylene is attackedwith decaborane to synthesize bis(4-bromophenyl)carborane, then a carborane viologen precursor B is synthesized through a Still coupling reaction, and finally the carborane viologen derivative is further obtained through the carborane viologen precursor A or the carborane viologen precursor B. Then, viologen is used as a central core structure, the carborane viologen derivative, ruthenium trichloride, cobalt dichloride or ferrous acetate are used as reaction raw materials, acetic acid is used as a solvent for reflux reaction, and finally, a product in reaction liquid is separated and dried tosynthesize the carborane viologen metal supramolecular polymer.

Synthesis and thermal properties of an acetylenic monomer containing boron and silicon

To improve the thermo-oxidative stability of acetylenic aromatic compounds, 1,2-bis(4-trimethylsilylethynylphenyl)-carborane (CBTMS) was designed, synthesized and characterized by FT-IR, 1H-NMR, 13C-NMR and mass spectrometry. The analysis of the DSC results showed that the acetylenic monomer had a melting point at 195.5 °C. The cross-linking process of CBTMS included a Diels-Alder cycloaddition reaction confirmed by FT-IR spectroscopy. Nonisothermal DSC studies showed CBTMS has an activation energy similar to that of the phenylethynyl-terminated compound. The thermoset and ceramic derived from the acetylenic monomer exhibited extremely thermo-oxidatively stable properties studied using thermogravimetric analysis (TGA). The thermoset showed a weight gain in air at elevated temperature and char yield of 98.8% at 1000 °C in air, and the ceramic residue had almost no weight loss up to 1000 °C in air. We demonstrated that trimethylsilylethynyl could be used as a crosslinking group for thermosetting polymers.

Photochemistry of hybrid organic-inorganic triarylborane-o-carboranes

Para- and meta-substituted o-carboranes with a dimesityl(phenyl)borane (dmpb) group, namely, p-1, p-2, m-1, and m-2, were prepared and their electronic natures were evaluated by steady-state photophysical methods. It was found that excited states were gre

O-carborane-based biphenyl and p-terphenyl derivatives

The synthesis and properties of biphenyl- and p-terphenyl-fused o-carboranes are described. Aryl rings in the biphenyl and p-terphenyl skeletons are highly coplanar because of the presence of the o-carborane unit. o-Carborane exhibits an electron-withdrawing character via the inductive effect, resulting in a decrease in both the HOMO and LUMO levels of oligophenyls without causing electronic perturbation.
