An organic solid with wide channels based on hydrogen bonding between macrocycles

Donor–Acceptor‐Substituted Phenylacetylene Macrocycles with Threefold Symmetry

“…After the mixture had cooled to room temp., the solvent was removed. Column chromatography (SiO 2 www.eurjoc.org were added. The mixture was poured into an ice-water solution of potassium iodine (10 g, 60.3 mmol) with vigorous stirring.…”

Self‐Assembled Nanoreactors

“…293 Recent advances in organic crystal engineering, particularly the rational design of complex solid architectures through supramolecular preorganization, have renewed interest in topochemical reactions. [294][295][296][297][298][299] Although not many catalysis experiments have been carried out with these organic crystals, it is worth mentioning the possibility in this review. Organic analogues to zeolites and mesoporous sieves were developed by Miller et al 300 They made catalytically active, nanoporous organic materials based on cross-linked lyotropic liquid crystals and demonstrated their use as efficient catalysts in Knoevenagel condensations.…”

Shape‐Persistent Macrocycles: From Molecules to Materials

“…[5] If the polar functional groups point to the outside of the macrocycle (extraannular substituents, Figure 2, middle) this may lead to the formation of a 2D network in the solid state. [6] Shape-persistent macrocycles with polar groups pointing to the inside (intraannular substituents, Figure 2, right) play a special role in supramolecular chemistry.…”
