However, there is a shortage of high\u2010performance single\u2010component ambipolar OMIECs, along with the issue of performance mismatch between p\u2010type and n\u2010type. Here, we copolymerized diketopyrrolopyrrole with selenophene serving as the\n                    <jats:italic>\u03c0<\/jats:italic>\n                    \u2010bridge to synthesize a new ambipolar polymer, P(gTDPPSe).

Vertical OECTs of P(gTDPPSe) were fabricated, which demonstrate balanced and remarkable performance in both p\u2010type and n\u2010type modes, achieving peak transconductance of 192.9 and 117.6 mS, respectively.

Building upon this, the P(gTDPPSe)\u2010based inverter achieved a maximum gain as high as 163 V\/V.
