We have recently reported that color-tunable TSCT polymers could be obtained via end group engineering of polystyrene synthesized from a single-fluorophore initiator , thanks to the synthetic flexibility of atom transfer radical polymerization (ATRP) . Specifically, structurally distant TSCT from the polymer chain end to the acceptor-type fluorophore was induced by an unexpected chain-end deactivation. Thus, continuous emission wavelength tuning could be achieved by varying the polymer chain length. However, despite the simplicity and tunability of the approach, the range over which emission could be manipulated was limited (maximum emission wavelength, λem = 460-540 nm in solid film). Moreover, the finite end group engineering is not widely applicable to other polymeric systems. We hypothesized that a structurally simple TSCT polymer platform with full-color emission might be achievable if electron-donating groups with tunable degrees of -conjugation could be incorporated into a single-acceptor fluorophore-based polymer system by a general approach.
