Description

General description

Squaraine probes feature a distinctive squaric acid derived aromatic ring which leaves the probe vulnerable to nucleophilic attack which destroys its fluorescent ability. This limitation has historically prevented these probes from being studied as much as other probes. However, recent advancements in their synthetic design has helped address these challenges and brought them to the forefront of fluorescent imaging. Squaraines are valued for their extremely intense absorption bands, good photoconductivity, excellent photostability, and high quantum yield.
