“…Fluorescent molecules have long been used to visualize (nano)particles, to stain cells or distinct cell parts, or parts of living organisms . In the context of polymer science, fluorescent labels have been used to visualize the interaction of bioactive polymers with cells, or to image micro‐ and nanostructures using fluorescent or confocal microscopy . As with other functional groups, there are three basic strategies to include fluorescent probes into a polymer during synthesis: the fluorophore can either be part of the initiator, of a (co)monomer, or of the terminating agents of the target polymer.…”

The synthesis and characterization of a series of green‐, blue‐, and red‐fluorescent exo‐oxanorbornene acid and imide monomers carrying nitrobenzofurazan, coumarin, and rhodamin B, respectively, as fluorophores are presented. These monomers carry oxanorbornene as polymerizable unit, and are readily copolymerized with bioactive functional oxanorbornene monomers by ring‐opening metathesis polymerization, as demonstrated by gel permeation chromatography and NMR spectroscopy. Due to the ease of synthesis of these monomers, and their cost‐effectiveness compared many to other fluorescent probes, they are useful for biomaterial applications.

“…Using light as a control stimulus is an ideal approach due to the tunable and highly reproducible energy (wavelength) and resolution of light sources. To date, several methods have been demonstrated whereby photoluminescent images can be patterned using light . Common approaches to achieve photopatterned luminescence include the use of a photoacid to cleave a fluorescence quenching functional group.…”

New methods that yield covert fluorescent images are of significant interest for applications in anti-counterfeit technology. Printing methods that offer access to spatially controlled fluorescence intensity are needed in order to accurately reproduce unique and complex images. Herein, the use of photoreactive inks containing 9,9′-bis(anthracene)sulfoxide (AnSO) to create complex images with spatially controlled fluorescence intensity is presented. Under UV irradiation, the SO-bridge between anthracene units in AnSO is extruded to yield the highly luminescent molecule 9,9′-bianthryl (BA) in quantitative yields. The irreversible formation of BA is leveraged to create multidimensional fluorescent security features that can be patterned using light and easily interpreted using the CCD camera of a mobile phone.

Indigo, one of the most ancient and abundant dyes in human history, has recently emerged as a potential functional motif due to its intriguing photochemical properties. This review aims to provide insights into both the preparation of these molecules and their utilization in molecular systems. First, the synthesis of the indigo core as well as available methods to derivatize indigo are described to outline synthetic strategies to build the desired molecular structures. Then, the photochemical behavior of indigos is discussed, with particular focus on E-Z photoisomerization and photoinduced electron transfer. Connections between the molecular structures and their photochemical properties are highlighted and serve as guiding principles for designing indigos to be applied as photoresponsive tools.
