TL;DR: A polar homochiral 3D MOF constructed with cobalt(II) and a new ligand N-(1,3-dicarboxy-5-benzyl)-carboxymethylglycine (H4L) accommodates ordered helical water streams in its helical grooves, providing the first example of switchable ferroelectric and optical behavior through two-step reversible single-crystal transformation (SCSC).

TL;DR: Enantiomeric pairs of MOF crystals are reported, where achiral fluorophores adhere to the inner surface of helical channels via biology-like H-bonds and hence inherit the helicity of the host MOFs, eventually amplifying the luminescence dissymmetry factor of thehost l/d-CMOF.

TL;DR: A water-soluble rhodamine-based derivative (L) has been rationally designed for selective recognition of Al(3+) in aqueous medium with good sensitivity and induces a remarkable fluorescence enhancement along with obvious color change detected by the naked eye, due to the ring-opening mechanism of the rhodamines spirolactam.

TL;DR: Density functional theory calculations have been performed to provide the first detailed computational study on the mechanism and enantioselectivity for the [4 + 2] cycloaddition reaction of ketenes with N-benzoyldiazenes catalyzed by N-heterocyclic carbenes (NHCs).

TL;DR: A highly fluorescent chemosensor based on 1,8-naphthyridine with high sensitivity and selectivity toward Ni(2+)/Cu(2+) over other cations both in aqueous solution over a wide pH range (4-10) and in cellular environments was developed.
