TL;DR: Prepared MOFs that incorporate macrocyclic ethers into the structural ligands comprising the framework walls within which certain cationic guests can bind quantitatively and site-specifically, akin to the molecular docking of drug molecules within protein receptors are prepared.

TL;DR: Mechanically interlocked molecules (MIMs), in the form of donor–acceptor [2]catenane-containing struts of exceptional length, have been incorporated into a three-dimensional catenated metal–organic framework (MOF) at precise locations and with uniform relative orientations.

TL;DR: These crown ether based struts serve as excellent organic ligands to bind with transition metal ions in the construction of MOFs: the crown ethers BPP34C10DA and NPP36C 10DA in the presence of Zn(NO(3)4.H(2)O)O afforded the MOF-1001 and MOf-1002 frameworks, respectively.

TL;DR: Dynamic (1)H NMR spectroscopic investigations performed on one of these donor-acceptor [2]catenanes reveal that the pirouetting motion of the butadiyne-triethylene glycol chain occurs with a dramatically lower activation enthalpy, yet with a much higher negative activation entropy in water, compared to organic solvents.

TL;DR: The time taken to produce the ubiquitous and promiscuous receptor, which has become known as the little “blue box”, has been halved as a result of using a pH-responsive derivative of 1,5-diaminonaphthalene to displace the template employed during its synthesis.
