Synthesis of P-Triazole Dithienophospholes and a Cyclodextrin-Based Sensor via Click Chemistry

The synthesis of a series of highly luminescent, functional dithienophospholes via a click reaction is reported. Slight modification of the lateral aromatic substituents leads to a significant difference in their solid-state organization. In addition, a novel water-soluble beta-cyclodextrin hybrid is demonstrated to be an effective sensor for picric acid.
