MS-28: Theory and practice of supramolecular synthons in crystal engineering
| ||
| Session Abstract | ||
|
Control of the molecular arrangement in the crystal is an important issue in research fields such as pharmaceuticals and organic electronic materials, since the molecular arrangement in the crystal greatly affects the physical properties of the organic crystal. Control of crystal structure using supramolecular synthons has been actively studied for decades. Recently, it is becoming possible to reveal the details of the intermolecular interactions of supramolecular synthons by high-level quantum chemical calculations. We invite contributions concerning analysis of intermolecular interactions of supramolecular synthons by theoretical and computational methods and applications of supramolecular synthons for crystal engineering.
