Lecture
This lecture covers the supramolecular organization in the solid state, focusing on the shapes of pi-conjugated molecules, crystal structures, and packing arrangements. It discusses the different types of crystal structures, such as herringbone, columnar, and graphitic, observed in various pi-conjugated hydrocarbons. The lecture also explores the crystal structures of specific molecules like benzene, pentacene, and coronene, highlighting their packing arrangements and interactions. Additionally, it delves into the intermolecular electron delocalization and band structure in organic crystals, emphasizing the importance of molecular orbitals interactions and their impact on electronic properties.
