o -BzcDPE and p -BzcDPE have been synthesized and used as probes for strong acid detection. The probes contain aggregation-induced emission luminogens (AIEgens) that are incorporated with a benzimidazole-carbazole backbone. Both probes show turn-on green fluorescence with a good contrast in the pres...
