An ESIPT based fluorescent sensor 1 was developed, which could selectively detect and differentiate trivalent metal ions Cr3+, Al3+ and Fe3+ in aqueous medium. The cell imaging experiments confirmed that 1 can be used for monitoring intracellular Cr3+ and Al3+ levels in living cells.

2-Hydroxyphenylpyridine and 2-hydroxyphenylbenzoxazole derivatives were synthesized and their photochemical properties were investigated. The results indicated that photocleavage reaction was contr...
Developing efficient methods for real-time detection of Zn2+ level in biological systems is highly relevant to improve our understanding of the role of Zn2+ in the progression of Parkinson's disease (PD).

Near-infrared (NIR) emitting probes with very largeStokes' shifts play a crucial role in bioimaging applications, as the optical signals in this region exhibit high signal to background ratio and allow deeper tissue penetration. Herein we illustrate NIR-emitting probe 2 with very largeStokes' shifts (Δλ ≈ 260–272 nm) by integrating the excited-state intramolecular proton transfer (ESIPT) unit 2-

lifetime characteristics of newly developed NIR-emitting dyes. In this study, four NIR-emitting ESIPT dyes with different cyanine terminal groups were investigated to evaluate their fluorescence lifetime characteristics in a polar aprotic solvent such as CH2Cl2. By using the time-correlated single-photon counting (TCSPC) method, these ESIPT-based dyes revealed a two-component exponential decay (τ1 and τ2)
