A novel fluorescent probe (E)-3-ethyl-2-(4-hydroxystyryl)-1,1-di-methyl-1H-benzo-[e]indolium iodide (probe EDB) based on benzo[e]indolium was synthesized, which provided the simultaneous detection of SO32-/HSO3- and HSO4- ion with different emission channels. Based on the principle of ion-induced rotation-displaced H-aggregates, when treated with NaHSO4, a fluorescence enhancement at 580nm was observed...
A new benzothiazole-based fluorescent probe 2-(benzo[d]thiazol-2-yl)-4-(1,3- dithian-2-yl)phenol (BT) with two different reaction sites, a thioacetal group (site 1 for Hg2+), and O and N atoms of the benzothiazole dye (site 2 for Cu2+), was designed and synthesized. The probe BT showed ratiometric fluorescent response to Hg2+ and fluorescence quenching behavior to Cu2+, which induces naked-eye fluorescent...
A near-infrared (NIR) and colorimetric fluorescent probe was developed for palladium species via a palladium catalyzed deallylation reaction. In this probe, 6-hydroxy-2,3-dihydro-xanthene-indolium (CyH) was acted as the signal unit and an allyl carbonate group was acted as the recognition unit. This non-fluorescent probe molecule can release the relevant fluorophore after interaction with palladium...
A simple and reliable fluorescent nitrite (NO2−) probe, 2-(1H-phenanthro[9,10-d] imidazol-2-yl)aniline (PA), was rationally developed based on a novel NO2−-mediated diazozation and subsequent cyclization. The new sensing mechanism of the probe was confirmed by using NMR, IR spectra, control experiments and DFT calculations. The synthesized probe showed low pH dependence, fast and highly selective...
