Photo-cross-linkable light-emitting polymers for holographic patterning

Abstract

Blue light-emitting poly(1-phenyl-1-alkyne)s containing photo-cross-linkable vinyl pendants were synthesized and photophysically characterized. Photoluminescence quantum yields are virtually unchanged for pristine and photo-cross-linked films, showing excellent stability and light-emitting property of the insoluble polymer film after photo-cross-linking process. By using laser interference lithography technique, active submicron two-dimensional photonic crystal structures have been fabricated by exposure to UV light. The obtained high quality nanostructures demonstrate that these polymers are applicable in active photonic devices such as distributed feedback laser. Furthermore, the achievable resolution of these polymers is ∼50nm, implying that these polymers may find potential applications in active nanodevices.

Hyperbranched Polytriazoles: Click Polymerization, Regioisomeric Structure, Light Emission, and Fluorescent Patterning

“…Since the films of the hb -PTAs are emissive, we tried to utilize them to create fluorescent images. Luminescent polymers with good film-forming ability and high photolysis efficiency are promising candidate materials to be used in the photoresist processes for the generation of fluorescent patterns, which have potential applications in liquid crystal displays, light-emitting diodes, medicinal diagnostic biochips, etc. , The hb -PTAs are soluble and film-forming. They contain many azido, ethynyl, and triazolyl functional groups, which may be photolyzed, thus making the polymers photosusceptible.…”
