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.

Formylation of 2-(2-hydroxyphenyl)benzoxazole gave 5-benzoxazolyl-substituted 4-hydroxyisophthalic aldehyde, which served as a precursor to the synthesis of novel photochromic spiro[indoline-benzopyrans] containing a benzoxazole group at position 8 of the benzopyran moiety. The obtained compounds possess photochromic properties in solution.

Pyrophosphate (PPi) is a biologically important target. A binuclear system 3•2Zn is found to selectively recognize PPi, leading to a ratiometric fluorescentsensor at pH 7.4 in water. The binding event triggered a large fluorescence response (∼100 nm bathochromic shift) by turning on the excited state intramolecular proton transfer (ESIPT). Detection of PPi released from a PCR experiment indicated
