Calixarenes, chemical chameleons

Electrical properties of ITO/benzylated cyclodextrins (β-CDs (Bz))/Al diode structures

“…Organic materials have recently attracted a great interest as semi conducting materials [1][2][3] and have been successfully applied to electroluminescent devices [3,4], field-effect transistors [5,6], solar cells [7,8] and chemical sensors [9,10], in particular, molecular host-guest recognition systems such as calixarenes and cyclodextrins [10][11][12][13][14][15][16]. The latter have good physical and chemical stability, compatibility with large field applications and lead to low-cost devices.…”

Determination of association constant of host–guest supramolecular complex (molecular recognition of carbamazepine, antiseizure drug, with calix(4)arene)

“…p-t-Butyl calix(4)arene exist in cone conformation because of the hydrogen bonds that are present between the four hydroxyl groups at the so-called lower rim. The para positions of the phenol rings form the upper rim [22]. Fig.…”

“…Alternatively placing a bulky substituent on the upper rim also locks a conformation. The calixarene based on p-tert-butyl phenol is also a cone [22]. Calixarene cavities are capable of molecular recognition [23].…”

Extended Calix[4]arene-Based Receptors for Molecular Recognition and Sensing

“…Calix[n]arenes have been explored in depth as building blocks or molecular scaffolds for artificial receptors and supramolecular chemistry over the years because of their unique three-dimensional and tunable structures, together with the ease of functionalization [61-62]. The chemistry and applications of calix[n]arenes have been extensively discussed in several books [51-52, 55] and review articles [63-69].…”
