Abstract
Pyrrolopyrrole aza-BODIPY (PPAB), a dimeric BODIPY analogue containing a pyrrolopyrrole structure at the center, exhibits intense far-red and near-infrared (NIR) absorption and emission. Herein, tetracyanobuta-1,3-diene-appended PPABs (TCBD-PPABs) were synthesized by post-modification based on a [2+2] cycloaddition-retroelectrocyclization (CA-RE) reaction with tetracyanoethylene. Owing to the redshift of the PPAB absorption in the NIR region and the emergence of the intramolecular charge-transfer band in the visible region, TCBD-PPABs exhibit panchromatic absorption in the visible/NIR regions.
