Sensing of metal ions and anions is of great importance because of their widespread
distribution in environmental systems and biological processes. Colorimetric and fluorescent …

Calix [4] pyrroles are readily synthesized in one step from pyrroles and ketones. For several
decades, these macrocycles have been exploited as powerful anion receptors or ligands for …

A number of aza-and/or oxo-bridged calix [2] arene [2] triazines have been synthesized
through an unusually high yielding and efficient fragment coupling approach starting from …

Macrocyclic molecules contain rings made up of seven or more atoms. They are interesting
because they provide building blocks for synthesizing precise two or three dimensional …

Angew. Chem. Int. Ed. 2004, 43, 838–838 more recent development in this field is the …

Heterocalixaromatics, the heteroatom bridged calix (hetero) arenes, have been emerging as
new generation macrocyclic host molecules in supramolecular chemistry recently. Being …

Chiral pyrrolic macrocycles continue to attract interest. However, their molecular design
remains challenging. Here, we report a calixpyrrole‐based chiral macrocyclic system, calix …

Methylazacalix [n] pyridines (n= 4, 8) and methylazacalix [m] arene [n] pyridines (m= n= 2, 4)
have been synthesized by a convenient fragment coupling approach starting from 2, 6 …

The synthesis and anion binding properties of a new class of calixpyrrole analogue,
containing two carbazole subunits in lieu of two of the four acetone bridging elements …

Oxidation reactions of several furan derivatives as effective methods for the preparation of
key synthetic intermediates are reviewed. Depending on the oxidizing reagent the furan ring …
