Encouraged by these results, we synthesized additional copolymers of styrene and other PAMs. As expected, all polymers showed significant emission variation with the increase of the PAM feed fraction. As depicted in Figure , NDI-coAntMAc exhibited a transition from blue to orange emission, as the original fluorescence peak at 460 nm disappeared and a new peak at 590 nm appeared. Eventually, a yellow emission peak at 560 nm and a green emission peak at 530 nm were observed for NDI-co1VNaph and NDI-coVBp, respectively, at highest PAM feed fraction (Figures and). The CIE 1931 chromaticity diagrams confirmed the continuous color tuning process, which can be clearly observed with the naked eye in the photographs of the polymer powders depicted in Figures . Depending on the degree of π-conjugation in the polycyclic aromatic groups, other copolymers showed a similar trend in solid-state emission variation (Figure ). Notably, near-white emission could also be easily obtained by manipulating the PAM feed fraction (e.g., ~1%) in the NDI-coPyMA, NDI-coAntMA, and NDI-coAntMAc copolymers (Figures and).
