WebFour visible light triphenylamine-based oxime ester photoinitiators ( TP-1–4) were synthesized and confirmed successfully through 1 H NMR, 13 C NMR, and electron impact mass spectrometry (EI-MS) measurements as well as elementary analyses (EA). WebOxime compounds are used as antidotes for nerve agents. A nerve agent inactivates acetylcholinesterase by phosphorylation. Oxime compounds can reactivate acetylcholinesterase by attaching to phosphorus, forming an oxime-phosphonate, which then splits away from the acetylcholinesterase molecule.
