A fluorescent T-shaped benzimidazole was successfully incorporated into a bicyclic macrocycle to form a suitane through supramolecular templated-synthesis, resulting in enhanced fluorescence emission. This method provides a potential pathway for the development of new complex fluorescent materials by taking advantage of mechanical bonding and molecular packing.
A fluorescent T-shaped benzimidazole was successfully designed and interlocked in a bicyclic macrocycle to form a suit[1]ane through supramolecular templated-synthesis. Compared with the bare fluorophore, suit[1]ane requires nearly two times the concentration to initialize the aggregation-caused quenching effect in solution. Furthermore, an 8-fold higher solid-state fluorescence quantum yield (21.7%) is also achieved. By taking advantage of mechanical bonding and molecular packing, such fluorescence emission enhancement through formation of a suitane opens the way to new complex fluorescent materials.
