Synthesis and Photophysical Study of Tetraphenyl Substituted BODIPY Based Phenyl-Monoselenide Probe for Selective Detection of Superoxide.

Selenium containing tetraphenyl substituted BODIPY probe was successfully synthesized from respective selenium aldehyde and tetraphenyl pyrrole using Knoevenagel-type condensation. The product was characterized using various spectroscopic techniques ( H,  C, Se, B, and  F) and mass spectrometry. The probe was found to be selective and sensitive towards detection of superoxide over other ROS with a "turn-off" (quenched) fluorescence response.
