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

Single-crystal to single-crystal transformations in discrete solvated metallocycles: the role of the metal ion
Tia Jacobs,Leonard J. Barbour +1 more
TL;DR: In this article, solvated cobalt and zinc-containing metallocycles undergo SCTSCT transformations upon desolvation to yield close-packed forms; this is in stark contrast to the analogous cadmium-based metallcycle, which affords an empty, transiently porous phase upon desolation.

Dynamic Behavior of M6L4 Capsules in Solution and Crystalline States
TL;DR: The perfect host : A discrete Ru6L4 capsule was synthesized as a solution counterpart of networked Co 6L4 capsules, which can host various guests in the crystalline state using dynamic conformational changes.

Unraveling Confined Dynamics of Guests Trapped in Self-Assembled Pd6L4 Nanocages by Ultrafast Mid-IR Polarization-Dependent Spectroscopy
TL;DR: Ultrafast mid-IR polarization-dependent pump-probe spectroscopy is applied to probe the effects of two Pd6L4 self-assembled nanocages on the properties and dynamics of fluxional group-VIII metal carbonyl guest molecules and finds that the interactions between the Pd 6L4 nanocage and guest molecules act to alter the ultrafast dynamics of the guests.

Functional metal-organic quadrangular macrocycle as luminescent sensor for ATP in aqueous media
TL;DR: In this paper, a new metal-organic quadrangular macrocycle Co(III) complex was achieved via selfassembly by comprising anthracene moieties as fluorophores, while the tridentate N2O units containing amide groups as guest binding sites and communicators, for specific responses to adenosine-5′-triphosphate disodium over the other disodium 5′-ribonucleotides and inorganic phosphate anions.

Deciphering the perturbation effect of urea on the supramolecular host-guest interaction of biologically active hydrophobic molecule inside the nanocavity of cyclodextrins
TL;DR: In this article, the authors analyzed the supramolecular interaction and the formation of host-guest complex between the biologically active hydrophobic coumarin derivative and cyclodextrins by using several spectroscopic, calorimetric and microscopic techniques.
