Printed SWCNT‐Based p–n Junction Thin‐Film Near‐Infrared Photoresistors Enabled by a Sustainable Furan‐Derived π‐Conjugated Polymer

Advanced Materials Technologies, EarlyView.
A sustainable polymer–carbon nanotube bilayer enables efficient near‐infrared photodetection in a simple lateral planar p–n junction thin‐film architecture. Thermal side‐chain cleavage enhances interfacial coupling, shifts the dominant photoresponse from 800 to 1000 nm, and substantially improves device performance.
