Diazobenzene-containing conjugated polymers as dark quenchers.
The synthesis and photophysical characterization of new conjugated polymers (CPs) with alternating phenylethynylene and diazobenzene (azo-PPE) units were reported, which showed broadened absorption and no measurable fluorescence. Quenching studies showed that azo-PPEs displayed high efficiency over a wide wavelength range.
متن کاملMetal-ligand-containing polymers: terpyridine as the supramolecular unit.
New and interesting properties can be obtained from macromolecular architectures functionalized with supramolecular moieties, particularly metal-ligand complexes. Self-assembly, based on the selective control of noncovalent interactions, guides the creation of hierarchically ordered materials providing access to novel structures and new properties. This field has expanded significantly in the l...
متن کاملThiourea-based fluorescent chemosensors for aqueous metal ion detection and cellular imaging.
We describe three significant advances in the use of thioureas as reporting elements for metal-responsive fluorescent chemosensors. First, on the basis of the crystal structure of a chemosensor analogue, we provide a deeper understanding of the details of the thiourea coordination environment. Second, we describe a new generation of chemosensors with higher affinities for Zn(2+) and Cd(2+) than...
متن کاملCoumarin-Derived Fluorescent Chemosensors
Fluorescent chemosensors are highly valuable in a variety of fields including environmental chemistry, analytical chemistry, and bio-medicinal science. They have provided accurate, on-line, and low-cost detection of toxic heavy metal ions, anions, and enzymes with high selectivity and sensitivity. Coumarins, with the structure of benzopyrone, have many advantages including high fluorescence qua...
متن کاملMetal-tunable nanocages as artificial chemosensors.
Supramolecular assembly of predesigned organic and inorganic building blocks is an excellent tool for constructing welldefined nanosized molecular cavities. The nanocages can encapsulate and stabilize guest substrates, and chemical transformations can be catalyzed within these “microreactor” cagelike structures. Recently, synthetic strategies for constructing functional coordination cages with ...
