Peripherally Modified Tetraphenylethene: Emerging as a Room-Temperature Luminescent Disc-Like Nematic Liquid Crystal.

A blue-light-emitting liquid crystalline (LC) material was designed and prepared. By employing a twisted luminescent core (i.e.

A NBD-based simple but effective fluorescent pH probe for imaging of lysosomes in living cells.

NBDlyso with lysosome-locating morpholine moiety has been developed as a high selective and sensitive fluorescent pH probe. This probe can respond to acidic pH (2.0-7.

A mitochondria-targeted fluorescent probe for ratiometric detection of endogenous sulfur dioxide derivatives in cancer cells.

A new mitochondria-targeted fluorescent probe HCy-D, constructed by dansyl and hemicyanine fluorophores, for SO2 derivatives (HSO3(-)/SO3(2-)) was presented. This probe was designed based on a new FRET platform. HCy-D showed a ratiometric, sensitive and rapid response to HSO3(-)/SO3(2-).

An effective colorimetric and ratiometric fluorescent probe for bisulfite in aqueous solution.

We have developed the first two-photon colorimetric and ratiometric fluorescent probe, BICO, for the detection of bisulfite (HSO3(-)) in aqueous solution. The probe contains coumarin and benzimidazole moieties and can detect HSO3(-) based on the Michael addition reaction with a limit of detection 5.3 × 10(-8) M in phosphate-buffered saline solution.
