Condensation of aryl- and aroylhydrazines and thiosemicarbazide with 2-diphenylphosphinoyloxybenzaldehyde results in formation of the corresponding hydrazones and thiosemicarbazone. The products give rise to conformational equilibrium between rotational and Z,E isomers, which is strongly displaced toward the E,E,Z" isomer and is determined by the nature of substituent in the hydrazine fragment.
Developing specific and sensitive method for endogenous peroxynitrite (ONOO-) in living systems is valuable to understand its various pathological events. In this work, a simple and novel fluorescentprobe (HPP) based on aggregation induced emission (AIE) as well as excited state intramolecular proton transfer (ESIPT) processes for endogenous ONOO- detection was constructed containing a diphenylphosphinate
