TLDR
The principles, development and applications of crystalline molecular flasks, solid-state crystalline networks with pores within which pseudo-solution-state reactions can take place, are described.Abstract:
Crystalline networks containing empty cavities can host a variety of molecules but also promote reactions between guests. Through robust crystallinity and a pseudo-solution state (dynamic movements) within their pores, these crystalline molecular flasks enable the direct observation of species — including unstable intermediates — during a reaction by in situ X-ray diffraction.read more

Covalent stabilization: a sturdy molecular square from reversible metal-ion-directed self-assembly.
TL;DR: This work shows how a labile structure obtained from reversible transition-metal-directed self-assembly of rods and connectors serves as a template that can be converted into a sturdy structure of identical topology and similar geometry.
