Key words
self-assembly - encapsulation - supramolecular chemistry
Significance
In water, the rod-shaped amphiphile 3 self-assembles into porous capsular structures of up to several micrometers in diameter. The pores of these capsules close reversibly upon heating by dehydration and collapse of the ethylene oxide moieties.
Comment
Although there are several examples of synthetic capsules created by self-assembly, porous systems with a gated opening mechanism are relatively rare. The presented structure could be an interesting candidate for delivering vehicles and nanoreactors.
