Abstract

Open-shell oligomers and polymers have exhibited intriguing electronic and magnetic properties

making them highly desirable for a wide range of applications

including ambipolar organic field-effect transistors (OFETs)

photodetectors

organic thermoelectrics

and spintronics. Although open-shell ground states have been observed in certain small molecules and doped organic semiconductors

the exploration of open-shell ground-state conjugated polymers is still limited

and the strategies for designing these polymers remain obscure. This review aims to briefly introduce the theory and characterization methods of open-shell conjugated polymers

along with an overview of recent progress and applications. The objective is to stimulate further advancements and investigations in this promising area by shedding light on the potential of open-shell conjugated polymers and the challenges that lie ahead.
