Synthesis and color tuning of boron diiminate conjugated polymers with aggregation-induced scintillation properties

We report film-type scintillators based on conjugated polymers with aggregation-induced emission (AIE) properties and the modulation of their scintillation abilities by chemical modification. Alternating copolymers containing a series of boron diiminates with various substituents and comonomers were synthesized via the palladium-catalyzed cross-coupling reaction. The synthesized polymers showed AIE properties. In addition, the corresponding emission colors to photoluminescence were also obtained with X-ray excitation. These data suggest that the AIE-active polymers should be a promising platform for developing a function-tunable plastic scintillator.
