“…To understand the spontaneous scrolling behavior of nanoscroll, DLS [47] was employed to quantitatively detect the conformation change of the GO nanosheets. If GMCN was formed in the liquid stage, the average hydrodynamic radius distribution would significantly change [48]. As shown in Fig.…”

Graphene nanoscrolls with one-dimensional topological structure obtained by Archimedean-type spirals of graphene, inherit the intrinsic properties of the pristine graphene. They have some unique advantages, including open edges/ends, adjustable internal volume, and diameter. Notably, the accommodation of functionalized components in their open interlayer is potentially a fantastic strategy to promote the epoch-making progress in nanotechnology areas, including energy storage, environmental remediation, biotechnology, and smart devices. However, it could destroy the driving forces for the self-rolling of graphene nanosheets and thus it is still a challenge to prepare functionalized graphene nanoscrolls.Here, based on density functional theory prediction, we reported a feasible method to fabricate graphene oxide nanoscrolls with carbon nanotubes as the template. The method was driven by cation-π interactions, which were caused by metal cations that also acted as the adsorption center. Most importantly, the distinct mechanism and an acidity-dependent rule for the formation of graphene nanoscrolls were identified. Benefiting from the introduced metal cations and the macro three-dimensional hierarchical structure, the produced nanoscroll aerogel exhibited significantly improved adsorption performance toward different organic solvents with the adsorption capacities from 129.9 to 265.7 g g −1 . This work demonstrates a simple and efficient strategy to fabricate functionalized component-accommodated graphene nanoscroll, which could find important applications in various fields.

“…Yao and coworkers synthesized [3]rotaxanes using axles containing two separated triazole stations and two multicomponent stoppers (Scheme 5b). 81 By mixing axles A16a-d, P2, malononitrile 10, and dimedone 11 in one pot, two wheels could be initially threaded by the axles through interactions between P2 and the triazole stations, providing pseudo [3]rotaxanes. The subsequent base-catalysed three-component reaction of 10, 11, and the benzaldehyde units on A16a-d capped the pseudo [3]rotaxanes in situ to generate [3]rotaxanes R13a-d in 15-20% yields.…”

“…In the past few years, many elegant works on the construction of pseudo[1]rotaxanes and [1]rotaxanes have been developed on the basis of various mono-functionalized pillar [5]arenes [47][48][49][50][51][52][53]. In this respect, we also constructed a couple of pseudo[1]rotaxanes and [1]rotaxanes by using mono-functionalized pillar [5]arene derivatives [54][55][56][57][58][59][60][61][62][63][64]. Recently, we successfully constructed a series of light-responsive [3]rotaxanes by employing azobenzenecontaining chain molecule as axel and functionalized pillar [5]arene as wheel [65].…”

A series of azobenzene-bridged dipillar [5]arenes were conveniently synthesized by coupling reaction of aminoalkyl-functionalized pillar [5]arenes with azobenzene-4,4'-dioxyacetic acid or azobenzene-4,4'-dioxybutanoic acid in dry chloroform under the combinatorial catalysis of HOBt/EDCl. 1 H NMR, 2D NOESY spectra and single crystal structure clearly indicated that the unique bis-[1]rotaxanes could be formed by threading two diaminoalkylene units into the two cavities of pillar [5] arenes depending on the length of the diaminoalkylene chains. Under light irradiation at 365 nm, the trans-azobenzene unit transferred to cis-configuration, while the basic bis-[1]rotaxane structure was kept unchanged.
