- A New Fluorescent Chemodosimeter for Hg2+ with High Selectivity and Sensitivity in Water
Dengchen Yang, Meng Li and Chuanfeng Chen
Version of Record online: 24 OCT 2016 | DOI: 10.1002/cjoc.201600519
A new fluorescent chemodosimeter 1 based on tetrahydrohelicene imide was synthesized, and it showed high selectivity and sensitivity toward Hg2+ in water. The response time was within 0.5 min, and the detection limit of 1 for Hg2+ was 2.0×10−8 mol·L−1. Moreover, the response mechanism that Hg2+ promoted deprotection of dithioacetal groups of 1 to form its water-insoluble aldehyde precursor was also proposed.

Modifying anthracene ring with aldehyde group can transform anthracene with aggregation-caused quenching properties to AIEgen. The single-crystal structures analysis of AnA and AnDA showed that their structure characteristics are responsible for the AIE properties of AnA and AnDA. On one hand, the aldehyde group can cause steric effects to lower intermolecular π-π packing style in aggregated state. On the other hand, intermolecular H-bonding interactions can restrict the intramolecular rotation and suppress internal charge transfer. These results may supply a new simple method for the transformation from ACQphores to AIEgens on the point of the molecular design.
