Since the discovery of the unprecedented conductivity of doped polyacetylene by Professors Hideri Shirakawa, Alan McDiarmid and Alan Heeger in 1977 , there have been huge efforts to synthesize lightweight, conductive, flexible, chemically and thermally resistant polymers. Conductive polymers (CPs), especially those having small electronic band gaps, are promising materials for the production of flexible and lightweight optoelectronic devices, which are widely used in many high-tech devices including wearable smartwatches .
