“…β-cyclodextrin (βCD) and α-cyclodextrin (≥98%, αCD) were purchased from Fluka. Adamantyl-terminated poly(propylene imine) (PPI) dendrimer (with 16 adamantyl groups, G3-PPI-(Ad) 16 ), βCD heptathioether, and heptamine β-cyclodextrin ((NH 2 ) 7 βCD) were synthesized according to previously reported procedures. 2,2″([1,1′-Biphenyl]-4.4′-diyldi-2,1-ethenediyl)bis-benzenesulfonic acid disodium salt (Stilbene 3) was purchased from Lambda Physik.…”

A fundamental and systematic study on the fabrication of a supramolecularly assembled nanostructure of an organic ligand-capped CdS nanocrystal (NC) and multiple heptamine β-cyclodextrin ((NH(2))(7)βCD) molecules in aqueous solution has been here reported. The functionalization process of presynthesized hydrophobic CdS NCs by means of (NH(2))(7)βCD has been extensively investigated by using different spectroscopic and structural techniques, as a function of different experimental parameters, such as the composition and the concentration of CD, the concentration of CdS NCs, the nature of the NC surface capping ligand (oleic acid and octylamine), and the organic solvent. The formation of a complex based on the direct coordination of the (NH(2))(7)βCD amine groups at the NC surface has been demonstrated and found responsible for the CdS NC phase transfer process. The amine functional group in (NH(2))(7)βCD and the appropriate combination of pristine capping agent coordinating the NC surface and a suitable solvent have been found decisive for the success of the CdS NC phase transfer process. Furthermore, a layer-by-layer assembly experiment has indicated that the obtained (NH(2))(7)βCD functionalized CdS NCs are still able to perform the host-guest chemistry. Thus, they offer a model of a nanoparticle-based material with molecular receptors, useful for bio applications.

“…Another series of adamentyl-terminated PPI (G1-5) encapsulated with b-cyclodextrin were demonstrated by Meijer et al They studied the pH effect of the host-guest interaction for the formation of a pseudo-rotaxane and used it as a nanoreactor for the preparation of gold and platinum nanoparticles. 43 The stable interaction between protonated diaminobutane and cucurbituril (CB [6]) was also applied into the G1-5 PPI by Kim et al Up to 64 CB [6] were encapsulated on the surface of G5 PPI. 44 They also studied the morphology through atomic force microscopy (AFM) and the dethreading effect of CB [6] upon the addition of base.…”

“…The noncovalent synthesis of polyester dendritic bow-ties based on anhydrides 15 and 38 using the complementary bis-(adamantylurea)-glycinylurea system [170,171] at the focal point of the bow-tie was reported by Gillies and Fréchet (Schemes 29 and 30) [172]. The system allows the possibility of bringing together two orthogonally functionalized dendrons since it is not self-complementary.…”

Polyester dendrimers have been comprehensively reviewed starting from their first synthesis in the early 1990s by Hawker and Fréchet. Polyester dendrimers have attracted and continue to attract extensive interest because they are comparatively easy to make and because, whenever they have been tested, they have been found to be non-toxic. A number of different strategies for their synthesis have been examined and the methods employed for formation of the ester bond during dendrimer assembly have been summarized. The newest approaches, including the use of bifunctional orthogonally reacting dendrons and accelerated synthesis have been surveyed.
