The performance of the CG model was tested by performing simulations of preformed C8S3 nanotubes. The tubular double-wall formation was maintained, suggesting that the CG model is compatible with the nanotube structure. However, our CG model favours brickwork-like formations, whereas computational modelling of the optical properties of the C8S3 nanotubes suggest that herringbone arrangements can describe the experimental optical signature better . Potential reasons for this preference could be some lack of interaction directionality due to coarse-graining or the absence of stronger partial charges that would make up for the high polarisability of the aromatic core. Further refinement of the aromatic core could also improve the self-assembly behaviour of C8S3 molecules.
