A new intramolecular charge transfer based fluorescent turn-on ratiometric probe exhibiting high sensitivity for F− and CO2.
Dynamic adjustment of emission behaviours by controlling the extent of twisted intramolecular charge transfer character in excited state.
Intramolecular charge transfer (ICT) fluorescence has been widely investigated and exploited in sensor molecules. However, steric effects on the ICT fluorescence properties have rarely been reported so far, although research...
