摘要
Nonconjugated organic room-temperature phosphorescence (RTP) materials with a multicolor afterglow have wide application potential in high-level information anticounterfeiting. However, developing a feasible fabrication technique for this material with high mechanical properties and good reprocessability remains a huge challenge. Herein, we present a catalyst- and solvent-free strategy for the synthesis of nonconjugated intrinsic RTP vitrimers via a one-step multicomponent hybrid copolymerization of amine, epoxide, acrylamide, and boric acid. The product achieved ultimate tensile strength of 83 MPa and module of 726 MPa, and it can be easily reprocessed without apparent mechanical or optical degradation. Moreover, multicolor RTP properties are easily achieved by one-pot doping with different dyes via efficient triplet-to-singlet Förster-resonance energy transfer. This facile strategy enables the design of multicolor organic RTP vitrimers from commercially available monomers.
