a) Chemical structure of PM6. b) Schematic of PM6 film formation process by using the spreading property of polymer solution on water substrate, where only the positive S determined by the ST of host solvent, water, and polymer film allows spreading. c) Schematic of polymer film morphology: amorphous (red background) and ordered (green background) polymer chain stacking influenced by processing parameters. Excitons in the amorphous regions within the Förster distance rF will transfer to an ordered phase, contributing to ordered PL (dashed border), otherwise they will give rise to amorphous PL (bold border). d) PL (left) and absorption (right) spectra of PM6 in o‐xylene with 1 vol % CN (blue). Bands arising from ordered (amorphous) phase are shaded green (red). Thin black lines indicate the contributions of the (00) and (01) vibronic transitions to the ordered bands. e) Photographs of the high throughput platform (left) and resulting polymer films (right). f) Automated characterization, spectral feature extraction and application of the Spano model to obtain structural features. g) GPR to find the objective function that predicts structural features from experimental conditions.
