A ratiometric fluorescent probe for sensing Cu2+ based on new imidazo[1,5-a]pyridine fluorescent dye

A mitochondria-targeting ratiometric fluorescent probe for the detection of hypochlorite based on the FRET strategy

“…30 The data indicated that emission spectrum of imidazo [1,5-a]pyridine and absorption spectrum of rhodamine largely overlapped, thus giving efficient FRET process. Inspired by this, we chose imidazo [1,5-a]pyridine as FRET donor and rhodamine as FRET acceptor to produce a À OCl ratiometric probe (IRP).…”

“…30 Compound 1 (1.0 mmol) was dissolved in dry dichloromethane (20 mL) and triethylamine (3.3 mmol). The solution was cooled to 0 C with stirring under nitrogen atmosphere.…”

A FRET based ratiometric fluorescent probe for detection of sulfite in food

“…7 Therefore, ratiometric uorescent probes which are independent of the environmental effects are more desirable. [8][9][10][11] Also, they have large Stokes shis which can prevent serious self-quenching and uorescence detection errors. So far, only a few well-behaved ratiometric probes for sulte have been reported.…”

Synthesis of Dimeric Imidazo[1, 5‐a]pyridines and Their Photophysical Properties

“…Very recently, Cao and co‐workers reported the development of a ratiometric fluorescent probe for sensing Cu 2+ using the imidazo[1, 5‐ a ]pyridines as a new fluorescent dye. They performed the fluorescent imaging of Cu 2+ in living cells based on Cu 2+ ‐induced fluorescence resonance energy transfer (FRET) off‐on …”
