Multicomponent PFCAs Capture, Detection, Differentiation, and Aqueous-Phase Removal with Adaptive Luminescent Organic Cages

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, nonbiodegradable pollutants that accumulate in water, posing threats to human health and aqueous ecosystems. There is currently a need for technologies capable of both multicomponent detection and removal of PFA...

Allosterically Controlled Capture of Mutually Repulsive Guests With Positive Cooperativity and Ultrahigh Affinity

ABSTRACT A hexacationic cage incorporating three urea units can encapsulate two mutually repulsive anions in close proximity through a combination of hydrogen bonding and electrostatic interactions. This leads to exceptionally high binding affinities, with a K 1 × K 2 value of ap...
