Fluorescence Micropatterning by the Photo‐Anilide Rearrangement of Polymer Bearing Anilide Groups

Abstract

AbstractA fluorescent micropattern in a thin polymer film is fabricated via a photo‐anilide rearrangement of anilide groups in the polymer. Polymer bearing anilide groups are prepared by polymerization of N‐phenyl methacrylamide (PMA) and methyl methacrylate. The photo‐anilide rearrangement of the prepared polymer and the reaction of the produced amino groups with fluorescamine, are studied by using UV and IR absorption spectroscopy. The fluorescence spectrum of the fluorescamine‐treated irradiated polymer film shows a strong fluorescence in the range of ≈420–620 nm with a fluorescence maximum at 496 nm. The patterns exhibited very distinct fluorescence images in the colors of dark blue, sky blue, green, yellow, and red depending on the observed wavelength ranges.
