showing more significant emission enhancement compared to other matrices (e.g., MMA); (ii) copolymerization of an electron donor with moderate electron density (2VN and FluoMA) with limited loading resulted in further enhanced emission compared to styrene; (iii) strong donors with extended π-conjugation degrees (e.g., anthracene and pyrene) were introduced through copolymerization with styrene, and deep-red to NIR emission was observed accompanied with
