Ground-state triplet polymers have a unique electronic structure and properties that have many possible uses in electronic devices. In this study we demonstrated how a Genetic Algorithm combined with GFN2-xTB, a fast semi-empirical method, can find unique and novel π-conjugated organic co-polymer candidates with a stable triplet ground-state. Those candidates exhibit a small HOMO-LUMO gap, which was previously shown to promote a triplet ground-state electronic structure due to the frontier molecular orbitals getting closer in energy. The spin densities show the biradical nature of those candidates, and the delocalization of the two unpaired electrons over two different singly-occupied molecular orbitals. DFT calculations show a triplet ground-state stabilization for up to 4 eV for the oligomer, and we expect this value to be similar or greater for the full-length polymer.
