摘要: Methylpentaphenylsilole (MPPS) and tetraphenylethene (TPE) are two archetypal luminogens that show the novel effect of aggregation-induced emission (AIE). In this work, TPE moieties are attached to MPPS core as peripheral groups at 2, 5-and 3, 4-positions to generate new AIE luminogens. The resulting 2, 5-and 3, 4-BTPEMTPS adducts are weakly fluorescent in dilute solutions but become highly emissive as solid aggregates, verifying their AIE activities. Although weak in the absolute term, the emissions of the 2, 5-and 3, 4 …
