In molecular systems, the continuous overlap of atomic orbitals results in Molecular Orbitals (MOs). The interacting orbitals split into:

Because moving a charge requires moving its associated lattice distortion, polaron transport inherently demands higher energy expenditure than the movement of free electrons in rigid inorganic crystals. 3. Mechanisms of Charge Transport physics of organic semiconductors pdf

Organic semiconductors are typically carbon-based materials with a conjugated π-electron system. The electronic structure of these materials is characterized by a filled valence band and an empty conduction band, similar to inorganic semiconductors. However, the electronic states in organic semiconductors are more localized due to the weaker intermolecular interactions, leading to a higher degree of disorder. In molecular systems, the continuous overlap of atomic
