Highly Fluorescent Anthracene Polymers for Direct Photo Patterning
Abstract:Highly fluorescent anthracene polymers, linked by a alkylene unit, were examined for fluorescent patterning. The anthracene polymers were soluble in organic solvent such as chloroform, which allowed solution processing to afford fluorescent thin films using the spin coating method. The fluorescence intensity of the polymer solution as well as film was decreased upon exposure to a high energy UV source, due to the photodimerization of anthracene unit. Utilizing such fluorescence decay, a fluorescent polymer pattern was directly developed from the thin film using a photomask. The photo-patterning of the fluorescent anthracene polymer film afforded a convenient method of image formation and patterning of gap electrode.

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.
