Tables and summarize the predicted PL properties of the newly designed NDI-homopolymers (Appendix B) from the MLREM and BRANNLP models. The predicted values of λem from MLREM showed a correlation with the increasing electron density of the monomers (Table ), consistent with the observations from the previous styrenic polymer system . Evidently, the predicted values of λem range from 500 to 680 nm, corresponding to colors ranging from green to red. This implies that the newly designed polycyclic aromatic monomers (PAMs) may be capable of full-color tuning. Particularly, the predicted emission wavelengths for the designed polymers grown from PyMA and VPy are 683 and 670 nm, respectively, showing significant emission redshifts to the deep-red region in comparison to NDI-polystyrene (460 nm). Interestingly, the value reported for molecular co-crystals prepared from NDI and pyrene was only 576 nm, which is located in the orange emission region .
