Time-evolved, far-red, circularly polarised luminescent polymer aggregates endowed with sacrificial helical Si–Si bond polymers

Non-charged helical polysilanes (PSi) were spontaneously endowed with CPL on the order of gem = ±0.02 at 700 nm when non-helical red- and far-red π-conjugated polymeric (PF8DBT) aggregates were employed after ageing at 20–25 °C for 24 h, followed by PSi-selective photoscissoring at 313 nm for 60 s.

Tetraphenylfuran: aggregation-induced emission or aggregation-caused quenching?

Tetraphenylfuran, structurally similar to AIE-active siloles, exhibits the traditional aggregation-caused quenching, which is co-caused by the restriction of intramolecular rotation and the conjugation effect.
