TL;DR: Flu-1, a new design strategy for the development of fluorescent turn-on chemodosimeters toward OCl(-) was proposed by the removal of the C=N isomerization, which exhibited the off-on response for OCl(-), sensitively and selectively.

TL;DR: A new ratiometric colorimetric chemodosimeter toward cyanide anion was designed and synthesized by using intramolecular charge transfer (ICT) as a signaling mechanism and displayed apparent color changes from deep red to light yellow, which could be observed by naked eyes.

TL;DR: A new ratiometric fluorescent and colorimetric probe (Coum-1) was designed by tuning the π-conjugated bridge to affect the intramolecular charge transfer efficiency and successfully applied to the fluorescent microscopic imaging for the detection of CN(-) in HeLa cells.

TL;DR: Two new ratiometric fluorescent chemosensors, 3 and 4, are designed and synthesized by using intramolecular charge transfer (ICT) as a signaling mechanism and displayed apparent luminescence color changes upon the addition of Hg(2+) ion.

TL;DR: A new near-IR "turn-on" fluorescent chemosensor with high selectivity for Hg(2+) ions was designed according to the twisted intramolecular charge transfer (TICT) mechanism, and this naphthalenedimide-based sensor with long wavelength absorption and emission can be used to image intracellular HG( 2+) ions in living Hela cells.
