通过超分子模板法合成了一种具有荧光的T型苯并咪唑类化合物，并将其与双环大环化合物进行了互锁。与裸荧光团相比，suit[1]ane需要近两倍的浓度来初始化溶液中聚集引起的猝灭效应。此外，还实现了高8倍的固态荧光量子产率（21.7%）。通过利用机械键合和分子堆积，通过形成suitane的这种荧光发射增强开辟了新的复合荧光材料的道路。
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.
