The benzene dimer is the prototypical system for the study of pi stacking, and is experimentally bound by 8–12 kJ/mol (2–3 kcal/mol) in the gas phase with a separation of 4.96 Å between the centers of mass for the T-shaped dimer. The small binding energy makes the benzene dimer difficult to study … See more In chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading … See more The ability to fine-tune pi stacking interactions would be useful in numerous synthetic efforts. One example would be to increase the binding … See more A powerful demonstration of stacking is found in the buckycatcher. This molecular tweezer is based on two concave buckybowls with a perfect fit for one convex See more • Noncovalent interaction • Dispersion (chemistry) • Cation–pi interaction • Intercalation (biochemistry) See more The preferred geometries of the benzene dimer have been modeled at a high level of theory with MP2-R12/A computations and very large counterpoise-corrected aug-cc-PVTZ basis sets. … See more The conventional understanding of pi stacking involves quadrupole interactions between delocalized electrons in p-orbitals. In other words, aromaticity should be required for this interaction to occur. However, several groups have provided contrary evidence, … See more π systems are important building blocks in supramolecular assembly because of their versatile noncovalent interactions with various functional … See more WebAug 26, 2024 · Attach the end of one band to the bottom of the pallet, run it up the stack, over the top and down the other side.
