The synthesis and application of o-carborane-based macrocyclic arenes.

Two o-carborane-hybridized macrocyclic arenes have been synthesized via Friedel–Crafts alkylation of carborane diaryl derivatives. The single-crystal X-ray diffraction analysis clearly revealed their cavity structure and intermolecular interaction force. These novel macrocycles exhibited aggregation-induced luminescence and intramolecular charge transfer properties and also significant selectivity towards nitro explosive compounds. This work provided a method for the synthesis of hybridized macrocyclic arenes. [ABSTRACT FROM AUTHOR]
