Laser-Induced Thermal Imaging of Polymer Light-Emitting Materials on Poly(3,4-ethylenedioxythiophene): Silane Hole-Transport Layer


  • We appreciate 3M's cooperation with the LITI technology and LITI donor films, and we also thank Dow Chemical Co. for their material supply.


The addition of methacryloxypropyltrimethoxysilane to poly(3,4- ethylenedioxythiophene) has enabled laser-induced thermal imaging (LITI) of polymer light-emitting materials on a hole-transport layer (see Figure for example). The IVL (current–voltage–luminance) performances of the device patterned by the LITI process are comparable to those of typical spin-coated devices.
