Perylene- and phthalocyanine-pigment molecules were systematically modified and consequences were studied for their solid state properties. Thin films (1- 100 nm) of these compounds were prepared by physical vapor deposition on Si- based interdigitated microelectrode arrays or transparent insulating substrates such as (amorphous) glass or (single crystalline) alkali halides. Intermolecular interactions were probed by optical measurements in absorption and emission as well as by measurements of the electrical conductivity and the field effect (OFET). The morphology of films was studied by transmission electron microscopy (TEM) and atomic force microscopy (AFM).

Different interactions among the molecules and with the substrate surfaces allowed to prepare either crystalline or amorphous films. Crystalline films were characterized by strong chromophore coupling leading to characteristic splitting, well- defined shifts of optical absorption bands and emission mainly from excimeric species whereas the chromophore coupling in the amorphous films was suppressed sufficiently to provide a significantly increased photoemission yield from uncoupled monomeric states.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
