This paper discusses processes for the limiting of optical radiation and the recording of thin amplitude-phase holograms in fullerene-containing conjugated organic structures based on polyimides in the near-IR region, using the radiation of an iodine laser at 1315 nm. It is shown that these structures are promising as nonlinear absorbers in the IR region and can be used for reversible recording of optical information.
