Vibrational Circular Dichroism Spectroscopy of Solid Polymer Films: Effects of Sample Orientation
TLDR
A theoretical approach is given on how to extract the true VCD spectrum out of superimposed spectra of anisotropic thin solid samples, which leads to the expected result, i.e., a zero line for achiral polymers. Expand
Strong solvent-dependent preference of Δ and Λ stereoisomers of a tris(diamine)nickel(II) complex revealed by vibrational circular dichroism spectroscopy.
TLDR
The observation that the solvent can significantly influence and shift an equilibrium between two diastereomeric forms is expected to have important implications on structural analysis and on how reaction mechanisms are rationalized. Expand
Contrasting reactivities of silicon and germanium complexes supported by an N-heterocyclic guanidine ligand.
TLDR
Attempts to isolate the corresponding silylene led to an unexpected ligand activation/rearrangement process involving N-C(aryl) bond cleavage within the N-heterocyclic guanidine ligand; this transformation was also studied by computational methods. Expand
Fast functionalization of multi-walled carbon nanotubes by an atmospheric pressure plasma jet.
TLDR
The afterglow of an atmospheric pressure plasma has been used for the fast oxidative functionalization of multi-walled carbon nanotubes (MWCNTs) and contact angle measurements show that this approach enhances the wettability of MWCNTs and reduces their sedimentation in an aqueous dispersion. Expand
Evidence of dihydrogen bonding of a chiral amine-borane complex in solution by VCD spectroscopy.
TLDR
IR and vibrational circular dichroism spectra of a chiral amine-borane in solution are investigated and unique VCD spectral signatures, which can be attributed to the formation of dihydrogen-bonded dimers in solution, are identified for the first time. Expand
Catalytic aerobic oxidation and tandem enantioselective cycloaddition in cascade multicomponent synthesis.
TLDR
The cascade synthesis efficiently yields structurally complex 5,5,5-tricyclic products with eight stereocenters with good yields and excellent diastereo- and enantiocontrol using one catalyst. Expand
General Enantioselective C-H Activation with Efficiently Tunable Cyclopentadienyl Ligands.
TLDR
The three-step gram-scale synthesis of a structurally diverse and widely applicable chiral Cp ligand collection (JasCp ligands) with highly variable and adjustable structures is described. Expand
Coaxing solid-state phosphorescence from tellurophenes.
The synthesis of the first examples of tellurophenes exhibiting phosphorescence in the solid state and under ambient conditions (room temperature and in air) is reported. Each of theseExpand
Solvent-induced conformational changes in cyclic peptides: a vibrational circular dichroism study.
TLDR
Using vibrational circular dichroism (VCD) spectroscopy, this study confirms previous NMR results which showed that D-2 adopts predominantly a βII turn structure in apolar and polar solvents and indicates a preference for a βI structure over βII in L-2. Expand
Synthesis and luminescent properties of Lewis base-appended borafluorenes.
TLDR
With a judicious choice of functional groups at boron, one can envisage the future generation of a whole library of 4-coordinate borafluorene-based luminogens that complement the efficient light-emitting behavior known for the widely studied borons-dipyrromethene analogues. Expand
