  • Overcoming False Optical Activity

    Many natural products are complicated organic molecules. Despite this complexity, scientists are usually able to investigate them using spectroscopic techniques. However, a team of researchers has now discovered that care should be taken using Raman spectroscopy to analyze certain chiral molecules ( more

  • Enantiomorph distribution maps for metals and metallic alloys

    The spatially resolved determination of which of the two enantiomorphic structural variants - the left-handed or the right-handed - of a chiral phase is present in a polycrystalline material is the focus of a publication in Science Advances. With the EBSD (electron backscatter diffraction) -based te more

  • Detecting the handedness of a single nanoparticle

    Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems have developed a new spectroscopic-microscope, which can be used to observe a single nanoparticle in real time. This enabled the first detection of a nanoparticle’s handedness while it is fr more

A Brief Guide to Types of Isomerism in Organic Chemistry

In organic chemistry, isomers are molecules with the same molecular formula (i.e. the same number of atoms of each element), but different structural or spatial arrangements of the atoms within the molecule. The reason there are such a colossal number of organic compounds – more than 10 million – is more

  • Water instead of mineral oil

    Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more

  • Molecules in the mirror

    In 1871 the children‘s book “Through the Looking-Glass – And What Alice Found There” by the English author Lewis Carroll, in which Alice enters a world behind the mirror, was published. She explains to her cat: “First there’s the room you can see through the glass – that’s just the same as our drawing room, only the things go the other way. …How would you like to live in Looking-glass House, Kitty? I wonder if they’d give you milk in there? more

Axial chirality

Axial chirality Axial chirality is a special case of chirality in which a molecule does not possess a stereogenic center (the most common form of chirality in organic compounds ) but an axis of chirality - an axis about which a set of substitu ... more
