Fig. 1: Designing a new generation of NIR-II D-A-D dyes by acceptor engineering strategy.
From: Acceptor engineering for NIR-II dyes with high photochemical and biomedical performance
a Previous NIR-II D-A-D dyes used BBT and PTQ as electron acceptors; b D-A-D NIR-II fluorophore structures of this work based on TQT acceptor.
