Exciton-polaritons are half-light, half-matter bosonic quasiparticles formed by strong exciton-photon coupling in semiconductor microcavities。 These hybrid particles possess the strong nonlinear interactions of excitons and keep most of the characteristics of the underlying photons。 As bosons, above a threshold density they can undergo Bose-Einstein condensation to a polariton condensate phase and exhibit a rich variety of exotic macroscopic quantum phenomena in solids。 Recently, organic semiconductors have been considered as a promising material platform for these studies due to their room-temperature stability, good processability, and abundant photophysics and photochemistry。 Herein, recent advances of exciton-polaritons and their Bose-Einstein condensates in organic semiconductor microcavities are summarized。 First, the basic physics is introduced, and then their emerging applications are highlighted。 The remaining questions are also discussed and a personal viewpoint about the potential directions for future research is given。
