α-Bridged BODIPY oligomers with switchable near-IR photoproperties by external-stimuli-induced foldamer formation and disruption.
We designed and synthesized a series of new α-bridged linear BODIPY oligomers, which exhibited strong absorption and high fluorescence efficiency in the near infrared region. The oligomers can be reversibly converted to the first NIR emissive BODIPY foldamers upon selective complexation with Cs(+).
