Fragmentation of molecule-induced γ-cyclodextrin nanotubular suprastructures due to drug dosage

Secondary assembly mechanism of cyclodextrin based on LiNTf2@β-CD system

“…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].…”

Recently, they discovered rodlike SA in a hemicyanine dye, 4-[4-(dimethylamino)-styryl]-1-docosylpyridinium bromide (DASPC22) and b-CD system [29].…”

Fluorescent probe studies of micropolarity, premicellar and micellar aggregation of non-ionic Brij surfactants

“…With decreasing polarity of the medium, the TICT fluorescence quantum yield increases with the blue shift of fluorescence due to the concomitant increase in the energy gap between S TICT 3 and S TICT o states as well as triplet state. In our previous work, the dipolar nature of DMASBT at its excited TICT state has been found to be very useful for the characterization of micelles [13] and cyclodextrins [25][26][27].…”

Formation of nanotubes and secondary assemblies of cyclodextrins induced by BBOT

“…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.…”
