Two [2]rotaxanes have been assembled in water from modular subunits through CuI-catalyzed azide–alkyne “click” chemistry. For this purpose, 2,6-disubstituted naphthalene axles with solubilizing oligo(ethylene glycol) (OEG) chains (n = 1–5) and propargyl terminal groups were synthesized and examined for their propensity to form inclusion complexes with a dicationic Diederich-type cyclophane host. The dependence of pseudorotaxane formation on the linkers between the naphthalene core and OEG chains, and in the case of ester linkers on different spacer lengths, was analyzed by titration experiments. In addition, the inclusion complexes of two [2]rotaxanes were trapped by using a water-soluble azide-functionalized stopper. Repetitive chromatography finally enabled the isolation of both mechanically interlocked [2]rotaxanes.
Post-assembly functionalization of organoplatinum(II) metallacycles via copper-free click chemistry

We describe the use of a strain-promoted copper-free click reaction in the post-self-assembly functionalization of organoplatinum(II) metallacycles. The coordination-driven self-assembly of a 120° cyclooctyne-tethered dipyridyl donor with 60° and 120° di-Pt(II) acceptors forms molecular rhomboids and hexagons bearing cyclooctynes. These species undergo post-self-assembly [3+2] Huisgen cycloaddition with a variety of azides to give functionalized ensembles under mild conditions.
Synthesis and optical properties of 6-substituted-β-cyclodextrin derivatives
Guo, Ruiyun,Bagui, Mahuya,Wei, Yongge,Peng, Zhonghua
experimental part, p. 604 - 612 (2010/06/15)
β-Cyclodextrin derivatives with varying lengths of π-conjugated arms have been synthesized. Their structures have been confirmed by 1H NMR, elemental analysis, mass spectrometry and X-ray crystal structure determination. Their self-inclusion properties ar
