Optical Limiting Properties of 3,5‐Dithienylenevinylene BODIPY Dyes at 532 nm

The optical limiting properties of a series of near infrared absorbing 3,5‐dithienylenevinylene BODIPY (boron‐dipyrromethene) dyes (1–3) that contain donor and acceptor moieties in their π‐conjugation systems were studied by using the z‐scan technique at 532 nm in the nanosecond pulse range.

Summary:The optical limiting properties of a series of near infrared absorbing 3,5‐dithienylenevinylene BODIPY (boron‐dipyrromethene) dyes (1–3) that contain donor and acceptor moieties in their π‐conjugation systems were studied by using the z‐scan technique at 532 nm in the nanosecond pulse range. A strong reverse saturable absorption response was observed when the compounds are embedded into poly(bisphenol carbonate A) polymer thin films, which demonstrates that BODIPY dyes with this type of structure are suitable for use in optical limiting applications. BODIPYs as optical limiters: The optical limiting properties of a series of 3,5‐dithienylenevinylene BODIPY dyes with D‐π‐A type structures were studied by using the z‐scan technique at 532 nm in the nanosecond pulse range. An unusually strong reverse saturable absorption response was observed when the compounds are embedded in poly(bisphenol carbonate A) polymer thin films.
