In this work, borondipyrromethene (BODIPY)-based fluorescent and colorimetric probe SBP has been explored as a sensor for selective detection of Au3+. The probe SBP containing two vinyl phenol groups at C3 and C5 position on BODIPY pyrrole rings is prepared to extend its emission wavelength into the red region (656 nm) and also to serve as a new receptor toward Au3+. The probe displayed colorimetric change from blue to pink and fluorometric change from red to orange (up to 40-fold at 590 nm) in aqueous medium, with the detection limit of 0.0094 μM. This colorimetric and fluorometric changes are caused by the oxidation of the double bond in the SBP facilitating by hydroxy group which is confirmed by detected intermediates from mass spectroscopy experiment. In addition, the “turn on” SBP probe is successfully applied for monitoring intracellular Au3+ in living RAW264.7 macrophages through fluorescence imaging.

An efficient and chemoselective route for transforming BF2-BODIPYs to Et2B-BODIPYs (masking) was developed using Et2AlCl. The Et groups can be easily replaced with F atoms using BF3·Et2O in moist CH2Cl2 to regenerate the BF2-BODIPYs (demasking). The masking-demasking strategy is very useful for synthesizing functionalized BODIPYs via nucleophilic and reductive reactions. The masking strategy was used to synthesize a BODIPY dimer by McMurry coupling of a formyl Et2B-BODIPY, while a new BODIPY with an asymmetrically substituted B-center was synthesized using the demasking strategy.

New molecular triads composed of closely spaced ferrocene-boron dipyrrin-fullerene, 1 and triphenylamine-boron dipyrrin-fullerene, 2 are synthesized, and photoinduced electron transfer leading to charge stabilization is demonstrated using a femtosecond transient spectroscopic technique.
