Electron‐Rich Heptacyclic S,N Heteroacene Enabling C‐Shaped A‐D‐A‐type Electron Acceptors With Photoelectric Response beyond 1000 Nm for Highly Sensitive Near‐Infrared Photodetectors

Electron‐Rich Heptacyclic S,N Heteroacene Enabling C‐Shaped A‐D‐A‐type Electron Acceptors With Photoelectric Response beyond 1000 Nm for Highly Sensitive Near‐Infrared Photodetectors

Abstract A highly electron‐rich S,N heteroacene building block is developed and condensed with FIC and Cl‐IC acceptors to furnish CT‐F and CT‐Cl, which exhibit near‐infrared (NIR) absorption beyond 1000 nm. The C‐shaped CT‐F and CT‐Cl self‐assemble into a highly ordered 3D intermolecular packing net...
