Supramolecular Chemistry
Study of features of complex chemical species and organization through non covalent interactions. Van der Waals forces, pi pi interactions, hydrogen bonds, hydrophobic interactions.
Intermolecular forces
Determine physiochemical properties such as melting point and solubility.
Van der Waals Interactions
van der Waals interactions are the sum of attractive (dispersive) and repulsive forces.
Hydrophobic Interactions
Result from hydrocarbons repelling when in water.
Hydrogen Bonds
represented as XH…YZ, is an electrostatic interaction
between an electropositive hydrogen atom and two electronegative
atoms X and Y.
Carboxylic Acids
Self Assemble through H bonds.
Supramolecular Synthons
a structural unit in
the supermolecule which can formed by intermolecular interactions
When the same chemical
substance exhibits different crystal structures
