Photoinduced Fluorescence 'Turn-On' Micropatterning with Substituted Triphenylmethane Derivatives

摘要

Methods for the generation of patterned fluorescence images based on the "precursor approach" has gained great attention recently. The "precursor approach" enables rapid and cost-effective generation of patterned images without the need for additional wet developing processes. Conceptually, the 'precursor approach' is based on the use of a polymer containing a dye molecule that has different excited state electronic properties before and after external stimulation.
