Encapsulated dichloroethane-mediated interlocked supramolecular polymeric assembly of A1/A2-dihydroxy-octyloxy pillar[5]arene 1,2-dichloroethane monosolvate
Crystals of 1-(1,4-dihydroxy)-2,3,4,5-(1,4-dioctyloxy)-pillar[5]arene, C99H158O10·C2H4Cl2, were grown from a 1,2-dicholoroethane/n-hexane solvent system. In the crystal, the encapsulated 1,2-dichloroethane solvent is stabilized by C—H...π interactions and mediates the formation of an interlocked supramolecular polymer via C—H...Cl interactions

Constitutional Isomers of Pentahydroxy-Functionalized Pillar[5]arenes: Synthesis, Characterization, and Crystal Structures
We herein report the preparation
of constitutional isomers of pentahydroxy-functionalized
pillar[5]Âarenes via the deprotection of their benzylated derivatives
by catalytic hydrogenation. The structures of the obtained isomers
were then established using single crystal X-ray diffraction. We also
found that the yield distribution of the different constitutional
isomers was dependent on the nature of the substitution, as revealed
by HPLC analysis of the crude mixture. Finally, further characterization
of the separated constitutional isomers indicated that they possess
different melting points, NMR spectra, crystal structures, and stacking
patterns in the solid state
