A strongly blue-fluorescent disulfonated pyrenedimethacrylamide has been synthesized and its spectroscopic features tested in the presence of diquat (DQ) and paraquat (PQ) herbicides in water. UV–vis absorption revealed the formation of a 1:1 complex between the probe and the “quats”, the strongest binding with DQ occurring in acetonitrile (K=1.84×106M−1). Subsequent incorporation of the new pyrene...
