The top part is the process of synthesizing the polymer precursor PAA-NHS by free radical copolymerization of acrylic acid and acrylic acid-N-succinimide ester. ‘m’ and ‘n’ represent the copolymerization ratio of monomer AA and AA-NHS. The middle part is the chemical formula of four small molecules as luminescent centers. The following section shows the process of generating intrinsic polymer RTP materials by the reaction of small molecules with PAA-NHS through aminolysis coupling. Lightning represents 365 nm UV excitation source.
