“…The shapes roughly correspond to nanosheet structures after being fractured and replicated. This kind of nanosheet structure is apparently different from the nanotubes and their SA as reported before [23][24][25][26][27][28][29].…”

“…Later similar SA structures of CD nanotubes have also been reported by some other research groups [26][27][28][29][30][31][32][33]. Jaffer et al and Sowmiya et al found that trans-2-[4-(dimethylamino)styryl]benzothiazole (DMASBT) could induce the formation of CD nanotubes and their rodlike SA [26][27][28], although they suggested that the SA consisted of nanotubes filled with DMASBT only and no empty CD was involved [28].…”

Cyclodextrin-based nanotubes have been widely investigated and their secondary assembly (SA) behavior was found in our previous works. Here we report the self-assembly behavior between lithium bis(trifluoromethylsulfonyl)imide (LiNTf 2 ) and b-cyclodextrin (b-CD). Nanosheet structures with regular shape were obtained in the concentrated LiNTf 2 @b-CD solution. This phenomenon can be explained in terms of the SA mechanism of CD induced by the inorganic guest LiNTf 2 . LiNTf 2 and b-CD firstly forms nanotubes, and the nanotubes further stack with each other to form nanosheets by SA. We confirm that the hydrogen-bonding interaction contributes a lot to the formation of the nanotubes and their SA, and Li ? shows a special effect in the SA by inducing hydrogenbonding network between the adjacent b-CD to regularly pack the nanotubes.

“…4c-f. These secondary self-assemblies of nanotubes of 1:2 inclusion complexes for the formation of nanorod structure were already reported by Wu, Shen, and He (2006) and Sowmiya, Purkayastha, Tiwari, Jaffer, and Saha (2009). According to their inference, it can also be explained that even with low concentration of the guest molecules, the lesser amount of nanotubes could be formed with ␤-CD.…”

“…The fact that nanotubes could assembly further to form rod-like structures was discovered for the first time [29,31] and the concept of secondary assembly was suggested accordingly [31]. Recently, it was reported that trans-2-[4-(dimethylamino)styryl]benzothiazole (DMASBT) could induce the formation of -CD nanotubes and their secondary assembly [32,33], which further confirmed the viewpoint of us [29,31]. However, only a small amount of molecules has been discovered to induce CDs to form secondary assembly.…”

The study of cyclodextrin nanotubes is a significant topic among the self-assembly behaviors of cyclodextrins. We report herein the interaction of 2,5-bis(5′-tert-butyl-2-benzoxazoyl)thiophene (BBOT) with -, -, -cyclodextrins (CDs). It has been discovered that the reaction patterns of BBOT with CDs are remarkably different. -CD forms a simple inclusion complex with BBOT in a stoichiometry of 1:2 (guest:host). -CD forms a 1:1 inclusion complex with BBOT at its low concentration. At higher concentration of BBOT, the nanotube and secondary assembly of -CD are formed. As for -CD, the nanotube and secondary assembly are formed within the whole concentration range of BBOT studied. The structure of -CD nanotubes is different from that of -CD nanotubes to a certain extent.
