Structure characterization, optical\/electrochemical measurements, and density functional theory calculation demonstrate that the glycol side chain length does not have obvious effects on the backbone structure and charge delocalization, but exhibits crucial contribution to the film structural order, oxidation current, and ion doping capacity. The CPDT\u2010BT copolymer with optimized glycol side chain length (P3gCPDT\u2010BT) shows the best OECT performances with the normalized peak transconductance of 134.2 \u00b1 3.2 S cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    , charge carrier mobility and volumetric capacitance,\n                    <jats:italic>\u00b5<\/jats:italic>\n                    C* of 479.3 \u00b1 11.6 F V\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00a0cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    s\n                    <jats:sup>\u22121<\/jats:sup>\n                    .
