Recent developments for the investigation of chiral properties and applications of pillar[5]arenes in analytical chemistry

Catechol-Containing Schiff Bases on Thiacalixarene: Synthesis, Copper (II) Recognition, and Formation of Organic-Inorganic Copper-Based Materials

“…Synthetic macrocyclic compounds, such as calixarenes, thiacalixarenes, resorcinarenes, pillararenes, and others, have excellent complexing properties and are often selective for a certain substrate [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. The introduction of fragments of Schiff bases into the structure of (thia)calixarenes makes it possible to increase both the efficiency and selectivity with respect to metal cations.…”

The coming of age of water channels for separation membranes: from biological to biomimetic to synthetic

“…Because of their high p-electron density induced by the electron-rich hydroquinones in the macrocycle, pillararenes are known to exhibit superb hostguest chemistry such that they can form association complexes (via chemical bonds) with electron-deficient species. [106][107][108] In the pillararene family, pillar [5]arene is the most structurally stable, and higher homologues (i.e., pillar [6][7][8][9][10][11][12][13][14][15]arenes) can be synthesized via the expansion of the pillar [5]arene ring. One of the most facile methods to synthesize pillar [5]arenes is via the condensation reaction between 1,4-dimethoxybenzene and paraformaldehyde in the presence of a suitable Lewis acid as a catalyst (refer to Table 2).…”

Copillar[5]arene Chemistry: Synthesis and Applications

“…We first briefly describe the discovery and the main characteristics of the par-ent pillar [5]arenes, for which several review articles have already been published. [25][26][27][28] After defining the particular features of copillararenes, we review and compare the different synthetic strategies allowing their construction. Finally, some key applications and future perspectives are described.…”
