Abstract Conjugated polymers (CPs) have emerged as an interesting class of materials in modern electronics and photonics, characterized by their unique delocalized π-electron systems that confer high flexibility, tunable electronic properties, solution processability. These organic present a compelling alternative to traditional inorganic semiconductors, offering the potential for new generation optoelectronic devices. This review explores evolving role CPs, exploring molecular design strategies innovative approaches enhance properties. We highlight notable progress toward developing faster, more efficient, environmentally friendly devices analyzing recent advancements CP-based devices, including photovoltaics, field-effect transistors, nonvolatile memories. The integration CPs flexible sustainable technologies underscores revolutionize future photonic systems. As ongoing research pushes frontiers engineering device architecture, are poised play essential shaping next-generation prioritize performance, sustainability, adaptability.
