Nontraditional luminogens (NTLs) without large π-conjugated aromatic structures have attracted a great deal of attention in recent years. Developing NTLs with red-shifted and enhanced emissions remains challenge. In this work, we developed NTL composed three components, i.e., polymaleic acid (PMA), arginine (Arg), polyacrylamide (PAM), investigated its photoluminescent behavior mechanism. Compared the single components binary PMA/Arg/PAM solid exhibited two emission peaks at 510 562 nm higher quantum yields. Structural characterizations demonstrated that hydrogen bonds formed between nonconventional chromophores PMA Arg lead to more extended through-space conjugation rigidified conformations, which is fundamental reason for yield solid. addition, theoretical calculations proved excited-state proton transfer occurs carboxyl groups amino via photoexcitation, resulting dual This work provides deeper understanding photoluminescence mechanism based on multiple helpful guiding design emissions.

Abstract Nonconventional luminescent polymers have gained significant interest due to their outstanding water solubility, biocompatibility, solution‐processability, and scalability. Unlike traditional aromatic luminogens with extended π‐conjugation, distinctive photophysical properties arise from a mechanism known as clustering‐triggered emission (CTE). CTE involves the clustering of electron‐rich subunits, leading enhanced electron delocalization conformational rigidification, ultimately boosting photoluminescence (PL). Despite substantial advancements, challenges remain in optimizing efficiency PL tunability these polymers. This review delves into mechanism, examining recent advances regulating nonconventional The aim is uncover universal principles underlying mechanisms across diverse systems, providing theoretical foundation for further development potential applications materials fields such bioimaging, sensing, optoelectronics.
