Tailoring two-dimensional surfaces with pillararenes based host–guest chemistry

MXenes Functionalized with Macrocyclic Hosts: From Molecular Design to Applications

“…[54,55] In our previous research, a library of 2D smart interfacial materials was developed by immobilizing the macrocyclic hosts with stimuli-responsive features. [56] Moreover, 3D biomimetic nanochannels were further explored based on pillararenes using the host-guest system, which exhibited the gating behaviors to the external stimulus. [57] As a result of the cooperative effect and directionality of the noncovalent interactions, macrocyclic hosts-based MXene are beneficial to take merging advantages and achieve applications in the field of membrane separations, biosensors, and smart devices.…”

Engineering solid nanochannels with macrocyclic host–guest chemistry for stimuli responses and molecular separations

“…We formerly developed a library of smart interfacial materials by immobilizing the macrocyclic hosts with stimuli-responsive features. 15,16 To date, it should be noted that several groups have reported integrating host–guest systems for the creation of biomimetic gates. 17–20 As a result of the cooperative effect and directionality of the noncovalent interactions, host–guest chemistry-based nanochannels are beneficial for merging advantages and achieve applications in the field of membrane separation and smart devices.…”

Fullerene-containing pillar[n]arene hybrid composites

“…As a significant rising star in macrocycle chemistry, 1–8 the short rigid cylindrical structure of pillar[ n ]arenes (Scheme 1) 9,10 resembles the molecular architecture of carbon nanotubes, 11–13 and provides the possibility of introducing unique planar chirality 14–16 by functionalizing larger alkyl and aromatic groups. 17–19 In fact, pillar[ n ]arene could perform as an efficient structural basis for the synthesis of one-dimensional (1D) linear tubular structures, 20–24 and serve as an interesting additive for improving the physiochemical properties of another significant two-dimensional (2D) carbon material, graphene, 25–27 for example, to diversify applications in biomedicine and electrochemical sensor devices. 28–30 In particular, the zero-dimensional (0D) carbon structure, fullerene (Scheme 1), has a marvelous performance in various fields, such as materials, pharmaceuticals and biological science.…”
