• BODIPY-Triphenylamine
• Pyridium salt
• Aggregation-induced red emission
• BSA probes

Two novel red BODIPY-Triphenylamine with conjugated pyridines and one quaternary pyridium salt were synthesized. The long wavelength peaks of P(O)PA-BODIPY and P(P)PA-BODIPY which were located at 643 nm, 631 nm were predominant and the quantum yield of them was 0.16, 0.05, respectively, so both of them showed red fluorescence in THE P(P)SPA-BODIPY had a red emission peak at 624 nm and the quantum yield was 0.10. All the three compounds exhibited good aggregation-induced emission property. Furthermore, the fluorescence intensity of these dyes was strengthened continuously with increasing concentration of bovine serum albumin (BSA) which showed that these dyes could be used as BSA probes. Meanwhile, the detection limit of P(O)PA-BODIPY, P(P)PA-BODIPY and P(P)SPA-BODIPY for BSA was calculated to be 1.44 x 10(-7) M,1.52 x 10(-7) M, 5.37 x 10(-8) M,respectively. P(O)PA-BODIPY was applied to cell imaging and showed a good uptake by SK-BR-3 cells which suggested its promising application for biosensors.
