The target size of the MCNB was determined using density functional theory (DFT) calculations. We found that MCNBs have a higher strain energy than CNBs of the same size (for details, see Supplementary Fig. 1), and that the strain of the MCNBs is mainly induced during the final bond-formation step. Figure 2a,b … See more Our synthetic route to the MCNBs is shown in Figs. 3 and 4.

The making of aromatic molecular Möbius belts - ScienceDirect
WebAtomically precise synthesis of topological molecular carbons such as Möbius carbon nanobelts (MCNBs) represents a big challenge in synthetic organic chemistry as it requires careful control of both twist and strain. So far, only one singly twisted MCNB has been reported and the MCNBs with more than two twists remain unknown. Herein, we report … WebMay 29, 2024 · It suggested that it might be possible to create a nanobelt with a twist, a Möbius carbon nanobelt. in order to make the itsy-bitsy twisty carbon, some of the same researchers stitched together individual smaller molecules using a series of 14 chemical reactions, chemist Yasutomo Segawa of the Institute for Molecular Science in Okazaki, … http://synth.chem.nagoya-u.ac.jp/wordpress/publication/mobiusbelt-2?lang=en scooby\\u0027s arlington heights
