摘要: An easily synthesized (7-nitrobenz-2-oxa-1,3-diazole) NBD piperazine conjugate, NPC, has been successfully employed for the fluorogenic sensing of hazardous substance, formaldehyde (FA), based on inhibition photoinduced electron transfer (PET) as a consequence formimine creation, which was proven by ESI-MS analysis. The probe found to be highly selective with low response time 2 min. robust sensor NPC used demonstrate its practical applicability in detecting vapor phase FA through emissions from plywood samples. cell permeability also exploited possibility intracellular estimation using this probe.
