N2 - Optical properties of lead-iodide-based one-dimensional perovskite-type crystals [NH2C(I) = NH2]3PbI5 and [CH3SC( = NH2)NH2]3PbI5 have been investigated theoretically and experimentally. The electronic and excitonic structures are studied based on group theoretical consideration and first-principle band calculation. Strong one-dimensional anisotropy of the optical absorption spectra, large Stokes shifts (∼ 1.0 eV) and huge exchange energies (∼ 70 meV) indicate that the excitons in these crystals are one-dimensional Frenkel excitons.
