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.

Crystalline Cyclophane-Protein Cage Frameworks.

TL;DR: This work synthesized a library of organic cyclophanes and studied their electrostatic self-assembly with biological metal-binding protein cages (ferritins) into ordered structures, showing that cationic pillar[5]arenes and ferritin cages form biohybrid cocrystals with an open protein network structure.

Coordination polymers of organic polymers synthesized via photopolymerization of single crystals: two-dimensional hydrogen bonding layers with amazing shock absorbing nature

TL;DR: Crystalline coordination polymers of organic polymers (CPOPs) were synthesized via photopolymerization of Ag(I) coordination polymer of dienes which have a self-templating nature due to the formation of N-H···O hydrogen bonded layers.

Neutral versus polycationic coordination cages: a comparison regarding neutral guest inclusion

TL;DR: A neutral self-assembled container synthesized from a concave π-extended tetrathiafulvalene ligand and the cis-Pd(dctfb)2(cod) complex exhibits a good binding ability for fused polyaromatic substrates.

Snapshots of a solid-state transformation: coexistence of three phases trapped in one crystal

TL;DR: In this article, the authors investigated the process of guest extrusion from the nonporous molecular material [Fe(bpp)(H2L)](ClO4)2·1.5C3H6O (bpp = 2,6-bis(pyrazol-3-yl)pyridine), which occurs through ordered diffusion of acetone in a crystal-to-crystal manner, leading to dramatic structural changes.

Ligand-Based Phase Control in Porous Zirconium CoordinationCages

TL;DR: Zirconium-based coordination cages have received considerable recent attention as a result of their structural tunability and amenability to post-synthetic modification as discussed by the authors, although these structures h...
