Witryna8 lut 2024 · Aromaticity is an established and widely used concept for the prediction of the reactivity of organic molecules. However, in on-surface chemistry – where the interaction with the substrate can significantly alter the electronic and geometric structure of the adsorbates – the role of aromaticity is not understood. This is an important way of detecting aromaticity. By the same mechanism, the signals of protons located near the ring axis are shifted upfield. Aromatic molecules are able to interact with each other in so-called π–π stacking: The π systems form two parallel rings overlap in a "face-to-face" … Zobacz więcej In chemistry, aromaticity is a chemical property of cyclic (ring-shaped), typically planar (flat) molecular structures with pi bonds in resonance (those containing delocalized electrons) that gives increased stability … Zobacz więcej The term "aromatic" The first known use of the word "aromatic" as a chemical term—namely, to apply to compounds that contain the phenyl group—occurs … Zobacz więcej Importance Aromatic compounds play key roles in the biochemistry of all living things.
