摘　　要：Since the discovery of conductive polyacetylene,conjugated polymers have attracted considerable attention in the past decades for their applications in optoelectronic devices,such as organic field-effect transistors(OFETs),light-emitting diodes(OLEDs),and photovoltaics(OPVs).The intrinsic mechanical flexibility of conjugated polymers endows them as promising candidates for flexible and wearable electronics.Through iterative molecular design refinement and processing technique optimization,significant improvements in device performance have been made.The mobility has reached over 10 cm^(2)·V^(−1)·s^(−1),exceeding the benchmark of 1 cm^(2)·V^(−1)·s^(−1)set by their amorphous silicon counterparts.The conductivity of N-type polymer,poly(benzodifurandione)(PBFDO),exhibited a breakthrough over 2000 S·cm−1,making it an ideal conductor with excellent stability and solutionprocessability.The power conversion efficiency(PCE)of conjugated polymer-based solar cells hits 19%,comparable to the commercial polycrystalline silicon solar cells with 14%−19%PCE.Furthermore,conjugated polymers also show extinguished and promising performance in energy storage and biomedical applications.
