This work provides the first demonstration of chiral and plasmon-active 2D material, which shows the absorption sensitive to intrinsic circular polarization of light even in plasmon range of wavelengths. Materials sensitive to circularly polarized light at plasmon wavelength in infrared region were obtained by means of combining nonchiral plasmonic nanostructures based on Ti3C2Tx MXene flakes with chiral organic molecules. The appearance of the induced chiral dichroism signal is additionally confirmed by several theoretical calculations. After the experimental and theoretical confirmation of the optical chirality at plasmon wavelengths, the flakes are utilized for the polarization sensitive conversion of light to heat, as well as for polarization dependent triggering of plasmon-assisted chemical transformation.
