1H-detected magic-angle spinning (MAS) NMR experiments have revolutionized the studies of biological and inorganic solids by providing unparalleled sensitivity resolution. Despite these gains, homogeneous broadening, originating from incomplete removal homonuclear dipolar interactions under fast MAS, remains highly prevalent limits achievable In direct analogy to super-resolution microscopy methods, we show that resolution beyond currently MAS alone can be obtained experiment-driven...
We report the synthesis of a fluorescent polycyclic aromatic hydrocarbon dye with "symmetry‐broken" core, derived from related hexa‐peri‐benzo¬coronene core fluoranthene subunit. The fluorophore is composed pure carbon skeleton without heteroatoms and exhibits remarkable photo¬luminescence properties photoluminescence quantum yield up to 67% in toluene, exceeding that parent hexa‐peri‐benzocoronene by factor 30. single crystal X‐ray structure reveals distorted structure, which responsible...
In order to quantitatively investigate the kinetic performance and pore size distribution of carbon felt electrodes for application in vanadium redox flow batteries, theory cyclic voltammetry (CV) is derived a random network cylindrical microelectrodes on base convolutive modeling. this context we present an algorithm based use modified Talbot contour inverse Laplace transformation, providing mass transfer functions required calculation CV responses external finite diffusion space....
The photooxidative stability of a series doubly bridged anthracenes was evaluated after their preparation via twofold macrocyclization bis(resorcinyl)anthracene. Lightfastness correlates with the energy levels highest occupied molecular orbital (HOMO), resulting in superior tetraesters compared to tetraethers. lengths and steric demand linker only plays minor role for ester-based compounds, which can be prepared reasonable yields thus tested proof-of-concept organic light-emitting diodes....
