  • Duplicate or mirror? Laser light determines chirality of molecules

    Seven of the ten most frequent medications contain chiral agents. These are molecules that occur in right- or left-handed forms. During chemical synthesis both forms usually occur in equal parts and have to be separated afterward, because chirality determines the agent’s effect in the body. Physicis more

  • Lefty or righty molecules lend a hand to material structures

    As below, so above. That seems to be an operating principle for molecules that start with a basic chirality - or "handed-ness" -- and pass it on as they combine into larger structures. An international team that included Rice University materials scientist Edwin Thomas pried a new, fundamental detai more

  • Harnessing the power of light to tackle asymmetrical molecules

    No, molecules do not actually have hands. But scientists refer to them in this way when looking at asymmetric molecules that are mirror images of one another and therefore are not superimposable. Whether a molecule is a "lefty" or "righty" also influences how they behave -- critical information for 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
