Calix[n]arenes and its derivatives as organocatalysts

Photosensitized activation of diazonium derivatives for C–B bond formation

“…In addition, tetrasubstituted calix [4]arenes represent a very important class of macrocyclic compounds, and developing strategies to polyfunctionalize these macrocycle is therefore essential. 4,26 The possibility to trigger light-activated processes using these compounds could in the future lead to a new class of synthetic approaches toward these macrocyclic derivatives.…”

Potential of nonporous adaptive crystals for hydrocarbon separation

“…[221][222][223] Moreover, CA-based NACs are considered as materials with ''almost infinite possibilities'', which are widely used in various fields, especially in the field of hydrocarbon separation. 224,225 In recent years, many simulants of CAs, such as calix [3]acridan and calix [4]pyrrole, have arisen as optimal candidates for constructing NACs to separate hydrocarbons. 226 As important fine chemicals, the separation of 2-methylpyridine (2-MP), 3-methylpyridine (3-MP) and 4-methylpyridine (4-MP) is particularly important in the field of chemical pharmaceuticals.…”

Methylene-bridged naphthotubes: new macrocyclic arenes with great potential for supramolecular chemistry

“…E-mail: zhoujiong@mail.neu.edu.cn possibilities". [35][36][37] They are called CAs as a result of their calixlike structures. 38 CAs are a class of widely adaptable macrocyclic hosts due to their size-tunable cavities, and are acknowledged to be the third generation of macrocyclic hosts after crown ethers and cyclodextrins.…”

“…Calixarenes (CAs) refer to macrocyclic arenes composed of phenol units linked to methylene groups at meta -positions, and are regarded as macrocycles with “almost infinite possibilities”. 35–37 They are called CAs as a result of their calix-like structures. 38 CAs are a class of widely adaptable macrocyclic hosts due to their size-tunable cavities, and are acknowledged to be the third generation of macrocyclic hosts after crown ethers and cyclodextrins.…”
