Advanced Science, EarlyView.We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).

THE ANTAGONISM OF ACETYLCHOLINE AND OF QUATERNARY AMMONIUM SALTS [PDF]
Quarterly Journal of Experimental Physiology, 1937 1. The study of a number of antagonists in a variety of tissues shows that all drugs which antagonise acetylcholine also antagonise Me4N.2. The concentration of antagonist needed in any tissue to produce an equal intensity of antagonism is similar with acetylcholine and with Me4N.3.
