Supramolecular self-assembly of emissive conjugated molecules has gained tremendous attention over the past few decades. In this study, two dumbbell-shaped organogelators with a p-quaterphenylene core were synthesized and their gelation behaviors investigated. The two gelators exhibited aggregation-induced emission, which not only provided an in-situ method to optically study the gelation process but also endowed these self-assemblies with substantial applications in sensing explosives, such as picric acid. Quantitative studies showed that self-assemblies of p-quaterphenylene-based molecules displayed a better sensing performance for picric acid than those of the p-terphenylene counterpart and tetraphenylethene.
