New metal-coordination-inhibited charge transfer emission for terfluorenes: highly sensitive and selective detection for Hg2+ with ratiometric "turn-on" fluorescence response.
Two terfluorenes TFOH and TFN exhibit high sensitivity and selectivity for the detection of Hg(2+) with ratiometric fluorescence response. The sensory mechanism is attributed to a new metal-coordination-inhibited spiroconjugation-like charge transfer emission.
