With the serendipitous discovery of crown ethers by Pedersen more than half a century ago
and the subsequent introduction of host–guest chemistry and supramolecular chemistry by …

Macrocyclic structures are common synthetic targets in drug discovery,(1, 2) and therefore,
interest in their study is continuously increasing in this field.(3, 4) A classic example is …

Chemically induced switching of luminescence remains one of the more dramatic visual
phenomena to be found in a laboratory. The past sliver of this century provides enough …

Supramolecular optical chemosensors are abiotic molecular devices that bind analytes by
noncovalent interactions, producing a change in light absorption or fluorescence. This …

Many successful stories in enzyme engineering are based on the creation of randomized
diversity in large mutant libraries, containing millions to billions of enzyme variants. Methods …

Fluorescent molecules, with their almost instantaneous response to external influences and
relatively low-cost measurement instrumentation, have been attractive analytical tools and …

An efficient fluorescent receptor (E)-N-[(2-hydroxy-naphthalen-1-yl) methylene] thiophene-2-
carbohydrazide (THN) for Al3+ ions was synthesized and characterized by physicochemical …

In the case of the FG-H series, a minimal variation in the chemical structure of the probe
causes an appreciable change in the titration curve (see Figure 2 for some of the titration …

The synthesis, structure, and physical properties of macrocycles have fascinated chemists
for many years. Their inherent properties make them useful in areas as diverse as ion …

The anion-templated synthesis of different pseudopeptidic macrocycles has been studied in
detail by using a multidisciplinary approach. The reaction between an open-chain …
