This chapter discusses the excitons in organic-based nanostructures. In particular, two-dimensional Frenkel-Wannier-Mott (FWM) excitons in hybrid organic-inorganic nanostructures (quantum wells, quantum wires, quantum dots) are considered. Linear and nonlinear optical response of hybrid FWM excitons is calculated. Based on the fast energy transfer, new concept for light-emitting devices is proposed. Exciton energy transfer from organics to semiconductor nanocrystals and its possible application to carrier multiplication in quantum dots is mentioned. Finally, FWM excitons and polaritons in a hybrid microcavity containing crystalline organic layer and a resonant inorganic QW, are considered. First experiments demonstrating properties of hybrid structures are mentioned.Less
