A new amphiphilic pillar[5]arene: synthesis and controllable self-assembly in water and application in white-light-emitting systems

Abstract

A new type of amphiphilic pillar[5]arene with excellent surface activity was designed and synthesized successfully. Interestingly, this pillar[5]arene shows controllable self-assembly behaviour in water and can be applied in white-light-emitting systems.

A p-tert-Butyldihomooxacalix[4]arene Based Soft Gel for Sustained Drug Release in Water

“…The designed and prepared macrocyclic hosts [mainly including crown ethers (Liu et al, 2017;Morrison et al, 2017), cyclodextrins Larsen and Beeren, 2019), calixarenes (Wang et al, 2015;Tian et al, 2019), cucurbiturils (Kim et al, 2007;Wu et al, 2018;Xiao B. et al, 2019), and pillar[n]arenes (Xue et al, 2012;Sun et al, 2018;Ogoshi et al, 2019;Xiao T. et al, 2019)] and the investigations of their host-guest properties are the foundation of the development of supramolecular chemistry (Zheng et al, 2012;Yao et al, 2018;Zhang et al, 2019). As the third generation of macrocyclic compounds in supramolecular chemistry, calixarenes process several advantages, such as excellent flexibility, improved conformational mobility, and easy modification (Kim et al, 2012;Nimse and Kim, 2013).…”

“…Macrocyclic host compounds, mainly including crown ethers (Zhu et al, 2012;Liu et al, 2017), cyclodextrins (Lai et al, 2017;Li et al, 2019), calixarenes (Kim et al, 2012;Nimse and Kim, 2013), cucurbiturils (Kim et al, 2007;Barrow et al, 2015), and pillararenes (Xue et al, 2012;Ogoshi et al, 2016;Yao et al, 2017;Chen J. et al, 2019), are the foundation of the development of supramolecular chemistry (Dong et al, 2014;Sun et al, 2018;Gao L. et al, 2019;Xiao et al, 2019). During the past two decades, the syntheses, host-guest properties, and applications of macrocycles have been widely investigated Wu and Yang, 2019).…”

pH-Induced Transition Between Single-Chain Macrocyclic Amphiphile and [c2]Daisy Chain-Based Bola-Type Amphiphile and the Related Self-Assembly Behavior in Water

“…In addition, the regulation of the state of macrocyclic amphiphiles by introducing stimuliresponsive motif to macrocyclic amphiphiles is an efficient way to extend their applications. Therefore, external stimuli-responsive macrocyclic amphiphiles play important roles in many fields, such as injectable materials, sensing, and cell imaging (Chang et al, 2014;Himmelein et al, 2014;Wang et al, 2015;Yang et al, 2016;Himmelein and Ravoo, 2017;Gao et al, 2018;Hu et al, 2018;Sun et al, 2018;Lee et al, 2019;Li et al, 2019).…”

“…of pillararenes make them good candidates for the construction of macrocyclic amphiphiles. Several types of pillararenes-based macrocyclic amphiphiles have been reported up to now: (1) the non-symmetric pillararenes with half hydrophilic groups and half hydrophobic groups from non-symmetric monomers (Yao et al, 2012;Yu et al, 2013); (2) the difunctionalized pillararenebased macrocyclic amphiphiles from copillar [5]arenes (Gao et al, 2013); (3) monofunctionalized pillararene-based macrocyclic amphiphiles by linking hydrophobic tails to symmetric pillararenes (Jie et al, 2014); and (4) the symmetric per-functionalized pillararenes-based amphiphiles (Nierengarten et al, 2013;Chang et al, 2014Chang et al, , 2019aYang et al, 2016;Sun et al, 2018). The obtained macrocyclic amphiphiles from these methods displayed interesting stimuli-responsiveness and applications, indicating the importance of pillararenes-based macrocyclic amphiphiles.…”
