Mapping intermolecular bonding in C60

Mapping intermolecular bonding in C60

The formation of intermolecular bonds in C₆₀ has been investigated in detail at pressures below 2.2 GPa and up to 750 K. Fullerene samples were heated in a temperature gradient to obtain data on the formation of dimers and low-dimensional polymers along isobars. Intermolecular bonding was analyzed ex situ by Raman scattering, using both intramolecular modes and intermolecular stretching modes. ...

Computational study of three dimensional potential energy surfaces in intermolecular hydrogen bonding of cis-urocanic acid

Geometry and bonding in small „C60...nNim clusters

Small Nim(C60)n clusters with n1m<4 are studied using the tight-binding molecular-dynamics method generalized to treat heteronuclear systems. Our results confirm recent experimental deduction of the bonding behavior of Ni towards C60 . The direction of the charge transfer is found to depend on the geometry of the Nim(C60)n cluster. Furthermore, the present results reveal a striking dissimilarit...

Mixed Interfullerene Bonding Motifs in C60 based polymers

An unexpected discovery in fullerene chemistry has been the ease with which C60 units can covalently bond together to give rise to polymerized fullerene networks with a variety of structural architectures. Such fullerene-bridged arrays display varying dimensionality and interesting electronic (metallic behavior) and magnetic (ferromagnetism above room temperature) properties. The predominant C-...

Combined electrostatics and hydrogen bonding determine intermolecular interactions between polyphosphoinositides.

Membrane lipids are active contributors to cell function as key mediators in signaling pathways controlling cell functions including inflammation, apoptosis, migration, and proliferation. Recent work on multimolecular lipid structures suggests a critical role for lipid organization in regulating the function of both lipids and proteins. Of particular interest in this context are the polyphospho...
