Although Staudinger realized makromoleküles had enormous potential, he likely did not anticipate the consequences of their universal adoption. With 6.3 billion metric tons plastic waste now contaminating our land, water, and air, we are facing an environmental public health crisis. Synthetic polymer chemists can help create a more sustainable future, but on right path to do so? Herein, comprehensive literature survey reveals that there has been increased focus "sustainable polymers" in...
Aqueous redox flow batteries (RFBs) are attractive candidates for low-cost, grid-scale storage of energy from renewable sources. Quinoxaline derivatives represent a promising but underexplored class charge-storing materials on account poor chemical stability in prior studies (with capacity fade rates >20%/day). Here, we establish that 2,3-dimethylquinoxaline-6-carboxylic acid (DMeQUIC) is vulnerable to tautomerization its reduced form under alkaline conditions. We obtain kinetic rate...
Aqueous organic redox flow batteries (RFBs) are promising for grid-scale energy storage, but the development of stable, low-cost electrolytes remains challenging. Herein, azobenzenes were investigated as negative because their low molecular weight and commercial availability. The electrochemical properties cycling performance methyl red, an azobenzene dye, evaluated under alkaline conditions. Analyzing decomposition products revealed degradation through hydrazo bond cleavage. To attenuate...
WS(S2)(S2CNEt2)2 has been successfully employed in the aerosol-assisted chemical vapor deposition of WS2 at temperatures above 350 °C. This precursor was found to decompose primarily through loss H2S, CS2, and SCNEt. The deposits were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, Raman diffraction. exhibited plate-like structures growing vertically from substrate.
Cyanide coordination clusters have received attention for their electronic and magnetic properties. Here, we synthesized a new octametallic cyanide box encapsulating Cs+. The cationic complex Cs⊂[FeIII4(Tp)4NiII4(NMe2Tp)4(μ-CN)12]+ was crystallized as BF4− salt its structure reveals that the cesium ion interacts with twelve edges. These interactions are likely responsible remarkable stability of supramolecular assembly, which maintains integrity in solution, shown by NMR spectroscopy, mass...
Nonaqueous redox flow batteries (NARFBs) often suffer from reduced battery lifetime and decreased coulombic effi-ciency due to crossover of the redox-active species through membrane. One method mitigate this undesired is judiciously choose a membrane based on several criteria: swelling structural integrity, size charge(s) active species, ionic conductivity. Most research date has focused reducing by synthesizing modified molecules and/or new membranes. However, no standard protocol exists...

Catalyst-transfer polymerization (CTP) is a chain-growth method used to synthesize conjugated polymers. Although CTP works well for most donor-type monomers, the stalls with thieno[3,2-b]thiophene when using Ni catalysts. Previous reports have rationalized this result by suggesting that catalyst trapped in Ni0π-complex highly electron-rich arene. In study, evidence provided trap more likely NiII complex arises from oxidative insertion of Ni0 into C-S bonds thieno[3,2-b]thiophene. This...

Aqueous redox-flow batteries (RFBs) containing organic redox electrolytes are a promising technology for grid-scale renewable energy storage. Most currently under consideration these RFBs contain charge-storing molecules that drawn from narrow collection of molecular scaffolds, and undergo rapid decomposition, which results in high rates capacity fade. To inform efforts at developing more stable aqueous RFB electrolytes, it is critical the kinetics charge carrier decomposition its...
