Abstract
The reaction of α-amino-ω-methoxypoly(ethylene glycol) [M = 5000] or star α-amino-poly(ethylene glycol) [M = 20 000] with hemiesters of prednisolone dicarboxylic acids (succinic, glutaric, adipic, phthalic acid) has been used to prepare the corresponding conjugates. The rate of esterase catalyz...

Assembly of a metal-organic framework by sextuple intercatenation of discrete adamantane-like cages.
Abstract
We describe an infinite three-dimensional metal-organic framework composed of catenated polyhedral cages, in which the framework is achieved by mechanical interlocking of all of the vertices of the cages. The three-dimensional polycatenated framework shows twofold self-interpenetration in its crysta...

Abstract
Irreversible redox-induced relaxation processes occurring in a synthetic thread for rotaxane-based molecular devices are investigated; the results show that such a system in solution allows chemists to efficiently realize a nanosecond timescale/electrochemically-driven "conformational shaping" throu...

Abstract
Photoinduced multiple electron-transfer processes of a newly synthesized rotaxane with one acceptor and two donors are studied with the time-resolved fluorescence and absorption methods. In this rotaxane, zinc porphyrin (ZnP) with a crown-ether necklace is employed as a photosensitized electron dono...

Abstract
The number of synthetic methods enabling the preparation of ammonium-based rotaxanes has increased very rapidly in the past ten years. The challenge in the synthesis of rotaxanes results from the rather weak interactions between the ammonium-containing rod and the crown ether macrocycle in the pseud...

Abstract
We describe a strategy for assembling different macrocycles onto a nonsymmetrical rotaxane thread in a precise sequence. If the macrocycles are small and rigid enough so that they cannot pass each other then the sequence is maintained mechanically, affording stereoisomerism in a manner reminiscent o...

Abstract
In rotaxane 1, two co-conformations are populated in CDCl(3) at temperatures between 250 and 330 K. The thermodynamic parameters show strong enthalpy-entropy compensation, and a non-negligible heat capacity difference between the two forms.

Abstract
We probe dynamics with reorientation of single dye molecules spin-coated onto polymer films. Rotation jumps in transition dipole orientation are observed for approximately 30% of all single molecules. It is found for the first time that there are mainly three typical jumping patterns of orientation:...

Abstract
We report on some direct evidence that demonstrates the importance of the release of intranuclear DNA on transfection activity. The data show that transfection activity can be substantially enhanced by integrating a multifunctional envelope-type nano device (MEND) and a biocleavable polyrotaxane (DM...

Abstract
Realization of controlled binary switching in individual molecules is of fundamental importance for nanoscale electronics where the use of molecular components promises the flexibility of engineering performance through controlled organic synthesis. The active component of the [2]rotaxane molecule c...

Abstract
Biodegradable polyrotaxanes (PRXs) were synthesized from bis-amino-terminated poly(L-lactide) (PLLA) and alpha-cyclodextrin (alpha-CD), combined with capping by bulky end groups at the amino-termini of PLLA through enzymatically cleavable peptide linkages. The crystalline structure of the PRXs in th...

Abstract
Multivalent carbohydrate ligands have been prepared by assembling alpha-cyclodextrin-based pseudo-rotaxanes through "click chemistry". The inclusion complex formed by a lactosyl-alpha-CD conjugate and a decane axle carrying a lactosyl stopper at one extremity and an azido group at the other end was...

Abstract
A prototype, based on light-active fluorescent rotor grafted to beta-cyclodextrin, shows a good solvent viscosity-sensitive behavior due to the environment-dependent nonradiative decay. With the reversible photoisomerization of the cyanostilbene unit, the viscosity sensitivity of the molecular rotor...

Abstract
In this study, three cationic polyrotaxanes composed of multiple oligoethylenimine-grafted alpha-cyclodextrin rings threaded on a poly(ethylene oxide) chain have been synthesized and characterized, and investigated for gene delivery. All three cationic polyrotaxanes could efficiently compact pDNA in...
