Abstract The field of organic electronics has profited from the discovery new conjugated semiconducting polymers that have molecular backbones which exhibit resilience to conformational fluctuations, accompanied by charge carrier mobilities routinely cross 1 cm 2 /Vs benchmark. One such polymer is indacenodithiophene-co-benzothiadiazole. Previously understood be lacking in microstructural order, we show here direct evidence nanosized domains high order its thin films. We also demonstrate device-based high-performance electrical and thermoelectric properties are not intrinsic but undergo rapid stabilization following a burst ambient air exposure. polymer’s nanomechanical equilibrate on longer timescales owing an orthogonal mechanism; gradual sweating-out residual low weight solvent molecules surface. snapshot quasistatic temporal evolution electrical, this prototypical semiconductor investigate subtleties play competing timescales. Our study documents untold often overlooked story device’s dynamic toward stability.
